IMPORTANT
When re-assembling the unit, apply a `zinc-loaded’ jointing compound between the fuses and busbars, between the
busbars and phase assemblies and between the interconnection plates and the heatsink (BICC BX1 - Parker SSD Part No.
EA466241)
Observe all tightening torque levels, refer to Appendix E: “Technical Specifications” - Termination Tightening Torque (Frame H).
Phase Assembly Removal Procedure
1. Referring to Figure 8-1 (590+) or Figure 8-2 (591+), remove the M12 screw (A). Undo the four screws (B, C, D, E) which allows the CT plate and
fuse assembly to be removed.
2. Unplug the thyristor gate leads and the heatsink overtemperature leads from the relevant phase assembly trigger board. Remove the same leads
from the adjacent phase assembly or assemblies (this is necessary to gain complete access to the interconnecting plates.) If you are removing the
phase assembly from a 591+ (2Q) product, also disconnect the thyristor suppression lead from the trigger boards.
8-16 Routine Maintenance and Repair
3. Remove the trigger board by releasing the four M6 Sems nuts fixing the PCB to the assembly. If you are working on a 590+ (4Q), remove the
dummy trigger board, or if working on a 591+ (2Q) remove the thyristor suppression board. Remove the air duct from the top of the phase
assembly to gain access to the DC interconnection plates.
Do not remove the trigger board support spacers.
4. Remove the DC interconnection plates between the phase assembly and its adjacent assemblies, either output terminals or phase assemblies.
5. If changing an upper phase assembly on a 590+ or 591+ remove the top baffle. This is achieved by pushing out the two end flaps of the plenum
chamber and unclipping the top baffle from the top cover baffle stops and the top of the phase assemblies. Remove the vertical baffles between
phase assemblies.
6. If changing a lower phase assembly on a 590+, remove the lower air duct.
7. Remove the complete phase assembly by removing the four M6 Sems nuts at the top and bottom of the phase assembly.
NOTE
On the 591+ 2Q, the left hand screw retains the phase coding connection which should be pushed to one side before lifting the phase assembly.
Phase Assembly Fitting Procedure
1. Position the repaired or spare phase assembly on to the back panel spacer. (Remember to re-connect the coding lead to the bottom of the phase
assembly when working on a 591+ 2Q).
Check for correct orientation of the assembly. Fix in position with 4 x M6 Sems nuts and tighten to the correct torque level.
Refit the interconnecting plate stacks between the phase assemblies. A stack of three plates are used on a 1200 Amp unit, four on a 1700 Amp unit,
five on a 2200 Amp unit and six on a 2700 Amp unit. On a 4Q unit the plates interconnect both the upper and lower thyristors and adjacent phase
assemblies. On the 2Q unit the plates interconnect adjacent phase assemblies. Tighten to the correct torque level.
NOTE
a) When fitting a spare phase assembly there may be some misalignment to the new phase where the interconnection plates do not fit easily.
In this case, loosen the trigger support spacers which will allow adjustment of the support bars. Fit the interconnecting plates and re-tighten
all units, including spacers.
b) When re-assembling the interconnection plates it is important that a good electrical contact is made between the plates and the
aluminium heatsink. Apply a layer of `zinc-loaded’ jointing compound between the interconnection plates and the heatsink.
2. Refit the air duct on the phase assembly ensuring that the duct fits inside the side ducting of the phase assembly.
3. Refit the trigger board (thyristor suppression board or dummy board as appropriate) and secure with the M6 Sems nuts.
4. Reconnect the gate leads, thermostat and suppression lead as necessary. The gate leads cannot be fitted incorrectly as they are polarised by the
plugs.
5. Re-fit the top baffle (either plenum cover or lower 4Q air duct) and vertical baffles.
6. Replace the fuse.
7. Re-close the swing-frame.
8. Replace the trigger board connectors.

UDP Support
The Upload Download Protocol (UDP) can be used to transfer text files between the drive and a host computer using the
P3 port. Files that can be transferred using UDP are configuration files, language files and text “dumps” of all the
parameters shown on the MMI.
Configuration files and language files are formatted as Intel Hex files. The files contain a copy of the drive’s configuration
and may be transferred either from the drive to the host computer, or from the host computer to the drive. Transferring a
configuration file to the drive will over-write all the drive’s settings.
Language files contain information required to display parameters on the Display/Keypad in a language other than
English. These may only be transferred from the host computer to the drive. Contact Parker for further information.
MMI dumps are human readable text files showing all the parameters in the drive in the order they are shown on the MMI.
The files can only be transferred from a drive to the host computer.
System Port (P3) Set-up
When transferring data using UDP the communications settings used are:
Baud rate selected via the P3 BAUD RATE parameter, (Tag No 198).
1 Stop bit, (fixed)
No Parity, (fixed)
8 data bits, (fixed)
No flow control, (fixed)
UDP Transfer Procedure
UDP XFER (RX)
This is the transfer of either a language or a configuration file from the host computer to the Drive. The drive automatically detects whether the file is a
language file or a configuration file. Transferring a configuration file to the drive will over-write all the drive’s settings.
1. Connect the Drive to the host using the appropriate lead.
2. Using a standard communications package prepare the host to transfer an ASCII file. Remember to set-up the host's serial port first.
3. Start the transfer on the Drive by selecting UDP XFER (RX) on the MMI and pressing the UP (↑) key, as instructed.
4. When the Drive says RECEIVING, begin the file transmission.
5. The Drive automatically terminates the UDP transfer when it detects the end of the Intel Hex end-of-file record.
Serial Communications A-3
UDP XFER (TX)
This is the transfer of the drive’s settings as an Intel Hex file.
1. Connect the Drive to the host using the appropriate lead.
2. Using a standard communications package prepare the host to receive an ASCII file. Remember to set up the host's serial port first.
3. On the host computer, direct data received on the serial comms port to a file.
4. Start the transfer on the Drive by selecting UDP XFER (TX) on the MMI and pressing the UP (↑) key, as instructed. The drive says
SENDING.
5. When the transfer is finished, terminate the capture of serial data on the host computer.
MMI Dump Procedure
The MMI dump can be used to transfer all of the drive’s parameters or just those that have been changed from the default values. The format of the
data is human readable and may be used as documentation of the drive’s configuration.
DUMP CHANGED
This parameter is used in conjunction with DUMP MMI (TX). When TRUE, only those parameters that have been modified from their default value
are included in the dump.
DUMP MMI (TX)
This is the transfer of all parameters.
1. Connect the Drive to the host using the appropriate lead.
2. Using a standard communications package prepare the host to receive an ASCII file. Remember to set up the host's serial port first.
3. On the host computer, direct data received on the serial comms port to a file.
4. Start the transfer on the Drive by selecting DUMP MMI (TX) on the MMI and pressing the UP (↑) key, as instructed. The drive says
REQUESTED.
5. When the transfer is finished, terminate the capture of serial data on the host computer.

5703 Support
The 5703 Setpoint Repeater Unit provides the facility to run a line of drives in speed-lock without the use of a 5720 Quadraloc controller; for accurate
speed-holding, encoder feedback is required. Ratioed speed-locking is supported, although the unit is not intended to replace the Quadraloc in
applications requiring high accuracy.
A 16-bit speed signal is passed between drives via the P3 port on each Drive (a port otherwise used only off-line for the upload and download of
EEPROM data). The port operates RS232 compatible signal levels. The 5703/1 converts these signal levels to fibre optic signals for transmission, and
from fibre optics to RS232 for reception. Alternatively an external converter may be used to provide galvanic isolation and to convert the signals to
RS485 for transmission over longer distances than is recommended for RS232.
Hardware Description
The 5703 is housed in a DIN rail mounted box and is
provided with a cable to connect into the P3 port. The
cable is 400mm long to limit transmission errors, the
primary unit-to-unit interconnection is intended to be
achieved by a fibre optic cable.
The 5703 unit itself is simply an electric signal-to-light
converter and does not alter the signal in any way, this is
achieved within the software data of the Drive.
It is fitted with one fibre optic receiver and two fibre optic
transmitters, the fibre optic receiver has a fixed function to
receive data from the preceding unit while the transmitter
sends data to the following unit. The additional transmitter
can be used either to re-transmit the incoming signal or
provide a second transmission of the output signal, this
gives the unit wide functionality. When the link is in the
normal right hand position, assuming the board is
mounted with the fibre optics downward, the second
transmitter repeats the output signal. In the left hand
position it repeats the input signal.
The 5703/1 can be configured to point to any relevant
parameter in the block diagram, the default connections
are such that the scaled input is connected to the
"additional speed demand" and the output to the "speed
demand".

Commissioning the 5703/1
Input to the Drive
The speed setpoint from the 5703/1 enters the drive via the P3 port and, after scaling, is presented to the application as the
parameter 5703 IN::SCALED INPUT. In the default application, this is added to analogue inputs 1, 2 and 3, (ramped), to
form the setpoint. IN BASIC TACHO-FOLLOWER MODE, ALL THE ANALOG INPUTS MUST BE DISABLED TO
PREVENT LOSS OF ACCURACY, yet it may be necessary in some applications to provide analog inputs for trim signals
or inch setpoints:
1. The ramp input may be disabled by taking terminal C7 (Ramp Hold) permanently high; the ramp is automatically
cleared when the drive is quenched, and its output will never move from (exactly) zero. The ramp input may often be of
use in line master drives; but the ramp should be disabled in slave drives. Note that the P3 setpoint may be passed
through the ramp function; in such a case, the analog input to the ramp (terminal A4) is automatically disconnected.
2. Analog input 1 (terminal A2) is used for inch setpoints. During normal running, the terminal is shorted to 0V and the
deadband function is used so that no signal at all passes to the summing junction. The analog inch setpoints are set a
little above the threshold of the deadband so as to give the required inching speeds, forward or backward. Selection
between analog inching and absolutely zero analog input is thus accomplished automatically.
3. Analog input 2 (terminal A3) may be disabled by writing zero to its scaling block; this will normally be done through
the MMI at commissioning, but may be overridden by the serial link. Alternatively, this input may be used for a local
analog trim.
Output from the Drive
By default, the value transmitted from the drive is the SPEED DEMAND parameter.
A-8 Serial Communications
EI Bisynch ASCII Support
The drive can communicate using the EI Bisynch ASCII protocol without the need for a Technology Option board to be fitted.
NOTE
The P3 port is not physically compatible with a multi-point network.
This communications protocol comes under the heading of Binary Synchronous Communications Data Link Control (BSCDLC). This is all part of an
internationally recognised ANSI standard protocol called BISYNCH (Binary Synchronous) and is known by the abbreviation x3.28. It is widely used
by manufacturers of computers, computer peripherals, and communications equipment.
EI BISYNCH, the specific form of communication used, corresponds with the following full American National Standard definition:
• ANSI Standard: x3.28, Revision: 1976
• Establishment and Termination Control Procedures Sub-category 2.5:
Two-way Alternate, Non-switched Multi-point with Centralised Operation & Fast Select
• Message Transfer Control Procedure Sub-category B1:
Message Associated Blocking with Longitudinal Checking & Single Acknowledgement
This is known by the abbreviation ANSI - x3.28 - 2.5 - B1.
Features
• Configured using Function Block inputs
• Diagnostics using Function Block outputs
• Software-selectable Baud Rate
• Software-selectable Slave Address
• Direct tag access for all parameters

3. Tag Access
Each parameter in the Inverter’s menu system is identified by a unique Tag Number. Information is exchanged across the system by use of a two
character Mnemonic that is derived from the Tag Number.
NOTE
Refer to the Parameter Specification Table in Appendix D for a full list of tag mnemonics - see the MN column. Refer to the Notes column
which gives access information about each parameter.
Parameter Mapping
The algorithm to convert between tag number and 2 character mnemonics is:
if (TagNo < 936) then
m = INT ((TagNo + 360)/36) (INT: the integer part)
n = (TagNo + 360) MOD 36 (MOD: the remainder)
if m > 9 then
char_1 = ‘a’ + (m - 10)
else
char_1 = ‘0’ + m
end_if
if n > 9 then
char_2 = ‘a’ + (n - 10)
else
char_2 = ‘0’ + n
end_if
else
m = INT ((TagNo - 936)/26) (INT: the integer part)
n = (TagNo - 936) MOD 26 (MOD: the remainder)
char_1 = ‘a’ + m
char_2 = ‘A’ + n
end_if
The algorithm generates mnemonics containing only the characters ‘0’ to ‘9’, ‘A’ to ‘Z’ and ‘a’ to ‘z’.
4. PNO Access
For compatibility with the earlier 590 product, parameters may also be accessed using the ASCII PNO listed in the “EI Bisynch Binary Parameter
Specification Tables”, page A-19. For example, PNO 39 can be accessed with the mnemonic “27”.

Serial Communications A-13
EI Binary Support
This mode has many similarities with the ASCII mode, and so what follows is a summary of the differences to the ASCII mode.
Character Format
Each byte is transmitted as 11 bits rather than adapting the 10-bit format used by the ASCII mode. The format is represented by the following:-
1
Start bit (low)
7
Data bits (LSB first)
1
Control bit *
1
Even parity bit
1
Stop bit (high)
* 0 = Control character,
1 = Data character
How is the Information Transferred?
During serial communications, Drive acts as a slave and responds to messages sent from the Supervisor. Messages received from the Supervisor are
categorised into Main Messages and Continuation Messages.
The Binary mode introduces several different Control and Data Characters. Refer to “EI Bisynch Binary Message Protocol”, page A-15.
Response to a `Selection’ Message
The response is very similar to the ASCII mode but differs in that the ASCII (GID)/(UID) address is replaced by the Binary (INO), Instrument
Number. Also, the ASCII parameter mnemonic (C1)(C2) is replaced by the Binary (PNO) character.
