COMMS PORT

Use this block to configure the drive's P3 port.

Refer to Appendix A: “Serial Communications” - System Port P3 for further information.

The P3 port is a non-isolated serial communications port built in to the drive's Control Board.

It is used off-line (while the drive is stopped) for transferring and saving drive configuration

files using a personal computer (PC) running a serial communications program, or on-line

(while the drive is running) when using the Parker SSD Drives 5703 Setpoint Repeater Unit.

You can also use the P3 port to transfer configuration files by connecting to a PC running the

Windows ^TM compatible software package "DSELite". Refer to the DSELite manual

HA471486.

CONFIGURE DRIVE

This block contains many of the parameters required for configuring the drive.

NOTE The CONFIGURE DRIVE menu on the MMI contains a different set of

parameters, for set-up using the keypad.

CONFIGURE ENABLE: The operation of the Block Diagram is suspended and all Keypad LEDs

will flash whilst CONFIGURE ENABLE = TRUE.

NOTE The CONFIGURE ENABLE parameter is also available in the following MMI

menus for ease of use: CALIBRATION, CONFIGURE I/O

100 to 875 VOLTS

Sets the 100% value for Armature Volts VA. Set this value to match the motor in use. (Refer to ARMATURE V CAL in the CALIBRATION

function block).

ARMATURE CURRENT

523

Sets the 100% value for Armature Current IA. Set this value to match the motor in use.

FIELD CURRENT

524

Product code dependent AMPS

Sets the 100% value for Field Current IF. Set this value to match the motor in use. Note: this should be set to a minimum value if in Field Voltage

control - see FLD. CTRL MODE in the FIELD CONTROL function block.

AUTOMATIC SAVE

1220

FALSE/TRUE

When TRUE, changes made to parameters using the operator station are automatically saved to the drive’s non-volatile memory.

DUMP CHANGED

1169

FALSE /TRUE

This parameter is used in conjunction with DUMP MMI (TX) and DUMP BLOCKS. When TRUE, only those parameters that have been modified

from their default value are included in the dump.

UDP USE OP PORT

628

FALSE/TRUE

When TRUE the UDP transfer will be re-directed to the operator station port.

EMULATE 590P

162

0x0000 to 0xFFFF

When non-zero the drive emulates some behaviour of earlier firmware versions of the 590P, (firmware versions 5.x and 7.x). This behaviour affects

the time constants of the PID block, a number of parameters in the Field Control block, speed loop, and the linking of parameters in the function

block diagram (refer to "Emulating Earlier Software Versions". page D-11).

DEBOUNCE DIGIN

1172

FALSE/TRUE

When TRUE the drive adds a 3ms debounce filter to the digital inputs. This affects terminals C3 to C8, B8 and B9. The hardware connection between

terminal B9, (COAST STOP) and the control of the external contactor is not affected.

Programming D-35

CURRENT LOOP

Use this to setup the drive's conventional current/torque loop.

It takes the current demand, imposes limits through four clamps, and then uses a PI loop

to control the output.

The four separate clamps - current profile, inverse time overload, bipolar clamps and main

current clamp - the clamps are in series and lowest clamp takes effect. The resultant clamp

value can be seen in the diagnostics ACTUAL POS I LIM and ACTUAL NEG I LIM.

The internal inputs to this block are:

• the current demand from the speed loop or terminal A3 (selected via I DMD.

ISOLATE)

• the current limit clamps from CURRENT PROFILE and INVERSE TIME (note that

the bipolar clamps and main current clamp are resident in the CURRENT LOOP

block)

• current feedback from CALIBRATION.

The default configuration uses DIGIN 1 and DIGIN 3 for switching modes (BIPOLAR

CLAMPS and I DMD. ISOLATE respectively), ANIN 5 for setting the symmetrical

positive and negative current clamps.

I DMD. ISOLATE

119

DISABLED / ENABLED

Speed loop bypass; the current demand is taken from ANIN 2 (A3).

With I DMD. ISOLATE disabled, the current loop uses the current demand from the speed loop. With I DMD. ISOLATE enabled, ANALOG I/P 2,

terminal A3, supplies the current demand. With default scaling, 10V dc on terminal A3 is 100% current demand. An additional current input,

ADDITIONAL DEM, can be added to the current demand. The simplified diagram below, with reference to the default Block Diagram, shows how

the I DMD ISOLATE parameter selects the controlling loop.

ISOL DMD SOURCE

1275

ANIN 2 (A3) / FIELD I DEMAND

Selects the source of the isolated current demand.

¾ Setting ANIN 2 (A3) makes use of the A3 analogue input terminal as the current demand.

¾ Setting FIELD I DEMAND makes use of the current demand (%) at the field current controller, as the percentage armature current demand.

The use of this parameter is typically combined with parameters BEMF SOURCE, BEMF INPUT and 3-PHASE FIELD to apply the drive to field

weakening control of a motor field.

Programming D-39

Functional Description

Note 1: I DMD. ISOLATE removes speed loop

demand and selects analog I/P 2 as

current regulator demand.

I DMD. ISOLATE is overridden by

program stop and stop to return drive to

speed regulation.

Note 2: REGEN ENABLE = 2Q (NON-REGEN)

prevents negative current demand. Non-

regenerative drives use non-regen mode

irrespective of the REGEN ENABLE

parameter setting.

CURRENT PROFILE

Use this to clamp the current limit for applications where motors have a reduced ability to

commutate armature current at low field currents.

Normally this is required when using Field Weakening, although some motors exhibit commutation

limitations at higher speeds even with rated field current.

The input to the block is SPEED FEEDBACK from the SPEED

LOOP function block. The output of the block changes the current

limit clamp in the current loop.

• When SPEED FEEDBACK exceeds SPD BRK 1 (LOW), the

current profile begins scaling the current limit as set by IMAX

BRK 1 (SPD1).

• As the SPEED FEEDBACK increases toward SPD BRK2

(HIGH), the current limit is reduced linearly toward IMAX BRK2

(SPD2).

• When the speed exceeds SPD BRK2 (HIGH), the current limit

remains at the IMAX BRK2 (SPD2) setting.

CURRENT PROFILE

Parameter

Tag

Range

SPD BRK 1 (LOW)

32

0.0 to 100.0 % (h)

This is the motor speed at which current limit profiling begins.

SPD BRK 2 (HIGH)

31

0.0 to 100.0 % (h)

This is the upper speed limit at which current limit profiling ends.

IMAX BRK 1 (SPD1)

93

0.0 to 200.0 % (h)

This sets the current limit value at or below speed break-point 1, provided the other current limit clamps (inverse time overload, bipolar clamps and

main current clamps) are greater than this setting.

IMAX BRK 2 (SPD2)

33

0.0 to 200.0 % (h)

This sets the current limit value at or above speed break-point 2, provided the other current limit clamps setting (inverse time overload, bipolar

clamps and main current clamps) are greater than this.

DIAMETER CALC.

This block performs three functions.

DIAMETER CALC:

Used to calculate roll diameters in winder applications.

TAPER CALC:

Used to profile the tension demand with diameter.

TENS+COMP CALC: Used to provide additional torque to compensate for static and dynamic

friction, as well as load inertia.

These three functions are combined into one function block as they are functionally closely

coupled.

DIAMETER CALC calculates the diameter of a reel as a function of the reel speed and the line

speed. The resulting diameter is a percentage of the maximum full roll diameter. A lead section,

adjacent line section, or surface driven speed sensing device is required to supply the line speed

signal. The winder or unwind drive's motor speed feedback provides the reel speed input.

The ratio of the minimum core diameter to the maximum roll diameter determines the operating

range of the diameter calculator. Set MIN DIAMETER to that ratio using the expression:

Minimum Core Outside Diameter ÷ Maximum Full Roll Diameter x 100%

The magnitude of LINE SPEED is compared with MIN SPEED to determine when the diameter

calculator will operate:

• When LINE SPEED is above MIN SPEED the calculator is on

• When LINE SPEED is below MIN SPEED, DIAMETER is held at the last calculated

diameter

When EXTERNAL RESET is ENABLED, RESET VALUE is used as the diameter output.

NOTE In turret winder applications, LINE SPEED will usually be above MIN SPEED.

During roll changes, EXTERNAL RESET must be held ENABLED for the new

spindle until the web has been transferred and the diameter is calculated

properly. RESET VALUE must be set to the appropriate new core value for a rewind, or new roll diameter for an unwind.

RAMP RATE adjusts the filtering of the diameter output. Its setting is the time it takes for a 100% change in DIAMETER. For example, at the default

setting of 5.0 seconds, a 50% step change in diameter would take 2.5 seconds for the output diameter output to display the change.

-105.00 to 105.00 %

This will usually be configured to be the analog tacho input and scaled appropriately during calibration.

REEL SPEED

437

-105.00 to 105.00 %

This will usually be configured to be the drive's own speed feedback, i.e. encoder or armature volts feedback.

MIN DIAMETER

425

0.00 to 100.00 %

Set to the minimum core diameter (normally the empty core diameter) as a percentage of the maximum roll diameter.

MIN SPEED

426

0.00 to 100.00 %

This is the minimum LINE SPEED level below which the diameter calculation is frozen.

RESET VALUE

462

0.00 to 100.00 %

Normally for winders this will be set to the MIN DIAMETER value. It is the diameter preset used when changing rolls. This value will be preloaded

into the ramp (filter) output when EXTERNAL RESET is enabled.

EXTERNAL RESET

463

DISABLED / ENABLED

Sets and holds the diameter to the RESET VALUE when ENABLED.

RAMP RATE

453

0.1 to 600.0 s

This is used to smooth the output of the diameter calculator.

TAPER

438

-100.00 to 100.00 %

This defines the amount of tapering in the tension demand with diameter variation. When TAPER is positive, the tension demand is hyperbolically

decreased as diameter increases.

TENSION SPT.

439

0.00 to 100.00 %

This is the required tension setpoint.

TENSION TRIM

440

-100.00 to 100.00 %

This is the additional tension demand in the form of a trim.

STATIC COMP

487

Variable inertia compensation set-up parameter.

ROLL WIDTH/MASS

481

0.00 to 100.00 %

Scales the inertia fixed and variable compensations based on roll width. 100% = maximum roll width.

LINE SPEED SPT

498

-105.00 to 105.00 %

Used to calculate the line speed acceleration rate value for the fixed and variable inertia compensations.

FILTER T.C.

482

0 to 20000

The line speed acceleration rate value is calculated from the line speed input. The calculated rate value may have a large ripple content that can

disturb the motor torque. The rate signal is therefore filtered, and this filter has a time constant set by this parameter.

RATE CAL

483

-100.00 to 100.00

Scales the inertia compensation acceleration/deceleration rate value to 100% of the maximum line ramp rate. This parameter should be set to the

maximum time required to ramp from zero to full speed in seconds. If RATE CAL = 0.00, then this parameter is set externally through

NORMALISED dv/dt, otherwise, RATE CAL sets the inertia compensation acceleration/deceleration rate.

Note - Inertia compensation does not work well for line ramp rates above 100 seconds and therefore this parameter is limited to 100.00.

NORMALISED dv/dt

484

-300.00 to 300.00 %

Useful for large line ramp rates (>100 Secs). Tag an external signal to NORMALISED dv/dt to set the inertia compensation acceleration/deceleration

rate externally from the drive. Useful for ramp rates exceeding 100 seconds. The external signal must be normalised to 100% = the maximum line

ramp rate. Active only when RATE CAL = 0.00.

TENSION SCALER
