Firmware Update

UPDATING THE INVERTER FIRMWARE

Prepare SD card

Copy the new firmware to an SD card, ensure the file is named firmware.30x for the AC30V or firmware.30p for the AC30P and AC30D.

New firmware is available at www.parker.com/ssd/pdq or can be copied from the Parker Drive Quicktool “Drive Maintenance” task.

Perform the upgrade

CAUTION: DO NOT REMOVE POWER FROM THE INVERTER DURING THE FIRMWARE UPDATE.

Insert the SD in the inverter’s SD slot. Replace the GKP if necessary. The ”Update Firmware” will now be visible in the wizard menu. This is
accessed from the top menu by pressing the

key, (Soft Key 1).

To start the update, change the value from FALSE to TRUE. The inverter will restart once the process is complete.

Associated Equipment

Connect the associated equipment to a DC Fed AC30 in the following order:

A – Semiconductor fuses, rated to protect the dc supply unit and dc bus installation at maximum power.

B – Optional EMC filter.

C – AC line choke, see Note 1.

D – DC supply unit, for example 890CS, AC30 supply unit 380-x. (Refer to separate product manuals).

E – Semiconductor fuses, rated to protect the individual dc fed AC30 and its dc wiring.

NOTES:

1. The required AC line choke inductance value is determined by the total dc bus capacitance (dc bus) as:

Lac(µH) per phase = (1.05 x 10

)/C

dcbus

(µF)

The dc supply unit may also have minimum inductance requirements (see table over page) to satisfy (e.g., 3% for 890CS) or may
include an internal line choke (e.g., AC30 input unit 380-x).

2. The dc supply unit may be required to precharge the dc bus at power up. If so, the precharge circuitry should be rated (in terms of

peak power and impulse energy) to charge the total dc bus capacitance, and should be rated to carry 45W to the internal power
supply of each drive, without dropping more than 40V.

AC Motor Chokes

The maximum rate of rise of Volts (dv/dt) present on the motor terminals of the inverter, can be as high as 10,000V/

s. This can be

reduced by adding a motor choke in series with the motor.

Installations with long cable runs may suffer from nuisance overcurrent trips, refer to Appendix C Compliance - Cabling Requirements for
maximum cable lengths. An output choke may be fitted in the inverter output to limit parasitic capacitive current to earth. Screened cable
has a higher parasitic capacitance to earth and may cause problems in shorter runs. Contact Parker for recommended choke values.

Dynamic Braking Resistors

We can supply suitable braking resistors, found on the following pages. Alternatively, you can use the calculation on page 5-7 to help you
select alternative resistors.

We recommend using a thermal overload switch to protect the braking circuit. Refer to page 5-6.

♦

The inverter must be fitted with external braking resistors if braking is required

♦

The power stack must be fitted with external braking resistors, or used with an AFE or regenerative DC supply unit, if
braking is required.

WIRING DETAILS

WARNING

Do not apply external voltage sources (mains
supply or otherwise) to either of the braking
terminals: DB+, DB. This can lead to damage to the
inverter and installation, and risk to personnel.

Dynamic Braking Resistors

These resistor sets are designed for stopping the system at rated power. They are rated for 10 seconds in a 100 seconds duty cycle.

See Appendix F for Minimum Brake Resistor value for each individual inverter size.

RESISTOR SELECTION

These small, metal-clad resistors should be mounted on a
heatsink (back panel) and covered to prevent injury from
burning.

There are four resistor values available.

Obtain information on the peak power rating and the average power rating of the resistors from the resistor manufacturer. If this
information is not available, a large safety margin must be incorporated to ensure that the resistors are not overloaded.

By connecting these resistors in series and in parallel the required braking capacity can be selected for the application.

The minimum resistance of the combination and maximum dc link voltage must be as specified in Appendix F:

Circuit Breakers

We do not recommend the use of circuit breakers (e.g. RCD, ELCB, GFCI), but where their use is mandatory, they should:

•

Operate correctly with dc and ac protective earth currents (i.e. type B RCDs as in Amendment 2 of IEC755).

•

Have adjustable trip amplitude and time characteristics to prevent nuisance tripping on switch-on.

When the ac supply is switched on, a pulse of current flows to earth to charge the internal/external ac supply EMC filter’s internal
capacitors which are connected between phase and earth. This has been minimised in Parker inverter filters, but may still trip out any
circuit breaker in the earth system. In addition, high frequency and dc components of earth leakage currents will flow under normal
operating conditions. Under certain fault conditions larger dc protective earth currents may flow. The protective function of some circuit
breakers cannot be guaranteed under such operating conditions.

WARNING

Circuit breakers used with VSDs and other similar equipment are not suitable for personnel protection.

Use another means to provide personal safety. Refer to EN50178 / VDE0160 / EN60204-1

General Information

THIS EQUIPMENT IF USED INCORRECTLY IS POTENTIALLY DANGEROUS. THEREFORE UNDER NO CIRCUMSTANCES

SHOULD IT BE USED BEFORE THESE INSTRUCTIONS HAVE BEEN READ AND UNDERSTOOD BY THE END USER WHO

SHOULD BE APPROPRIATELY QUALIFIED TO OPERATE THE EQUIPMENT.

This section provides general information about Safe Torque Off (STO).
Two safety functions can be implemented with the inverter: STO and Safe Stop 1 (SS1). In order to meet all aspects of STO and SS1, an external safety

control unit should be used.
To implement Safe Stop 1 (SS1), the external safety control unit causes the drive to decelerate to rest. Once at rest, it invokes STO in the inverter.

Please refer to EN61800-5-2:2007 para 4.2.2.3 for the formal definitions.
It is the user’s responsibility to:

1) Risk assess the machine.
2) Design, implement and assess an appropriate solution for each application to meet all relevant safety requirements.

Note: STO is an electronic inhibit intended for use during normal operation of the machine. It is not intended for use during machine maintenance,

repair, replacement or other similar activities. For these activities recognised electrical power isolation devices and lock-off procedures should be used.
The inverter STO function is a factory-fitted and factory-tested feature. See the section “Safety Warnings and Limitations” on page 6-18.

Safe Torque Off

STO FUNCTIONAL DESCRIPTION

STO is a means of preventing an inverter from delivering rotational force to its connected electric motor. Please refer to EN61800-5-2:2007 para 4.2.2.2

for the formal definition.
To ensure a high degree of safety, two independent STO control channels are implemented in hardware. The STO circuit in the inverter is designed

such that a fault in one control channel will not affect the other channel’s ability to prevent the drive from starting, i.e. the STO function of the inverter is

tolerant to any single fault. It may not be tolerant to an accumulation of faults. This is in keeping with its declared safety ratings.
STO always overrides any attempt to start the drive. If one or both STO control inputs is requesting the STO function, the drive will not start, even if for

example, the drive’s software malfunctions and tries to cause the motor to turn.
The STO function is implemented in hardware; it overrides all software activities. The only software involvement is to report STO status to the user via a

Graphical Keypad (GKP), serial communications link or user terminal as defined by the drive configuration.

WARNING

THE DECLARED SIL/PL CAPABILITY OF THIS STO PRODUCT CAN BE ACHIEVED ONLY WHEN THE TWO STO USER INPUTS ARE

DRIVEN INDEPENDENTLY. THEY MUST NOT BOTH BE DRIVEN FROM A COMMON SOURCE; OTHERWISE THE SINGLE FAULT

DETECTION WILL BE COMPLETELY INOPERATIVE.

USE OF THE PRODUCT IN THIS “COMMON SOURCE” CONDITION INVALIDATES THE STO PRODUCT SPECIFICATION AND IS

ENTIRELY AT THE USER’S OWN RISK.

Alignment to European Standards

EN ISO13849-1:2008

(Safety of machinery – Safety-related parts of control systems)

STO aligns internally to the following aspects of this standard:



Architecture according to Category 3:

Solid lines represent the STO control paths.
Dashed lines represent reasonably practicable fault detection.
Key:

I1, I2 = user terminal

L1, L2 = logic

O1, O2 = methods of enabling or disabling output power devices

mxy

interconnecting means

= monitoring

= cross monitoring



Category 3 general requirements are:

A single failure, and any consequential failures, will not lead to loss of the STO safety function.
Failure of more than one component can lead to the loss of the STO safety function.
