Action
Make sure that the parameter settings related to the safety functions are set as defined in the option-
specific chapter.
Validation test
ABB recommends that you monitor at least these signals with the Drive composer PC tool:
•01.01 Motor speed used (rpm)
•01.02 Motor speed estimated (rpm)
•01.07 Motor current (A)
•01.10 Motor torque (%)
•06.18 Start inhibit status word
•23.01 Speed ref ramp input (rpm)
•23.02 Speed ref ramp output (rpm)
•90.01 Motor speed for control (rpm)
•When using an encoder, also: 90.10 Encoder 1 speed (rpm)
Make sure that it is safe to start, run and stop the motor(s) during the test.
Start the drive and make sure that the motor is running. If possible, use a motor speed close to the
maximum speed of the application.
Push an emergency stop button.
Make sure that the drive stops the motor(s) as follows:
•ACS880-07CLC/07LC/17LC/37LC drives with option +Q951+Q984: The drive activates the STO
function. The motor coasts to a stop.
•ACS880-07LC/17LC/37LC drives with option +Q952+Q984: The drive decelerates the motor to a
stop according to a user-defined ramp. The drive then activates the STO function.
•ACS880 multidrives with option +Q951+Q984: The motors coast to a stop.
•ACS880 multidrives with option +Q952+Q984: The drive decelerates the motors to a stop according
to a user-defined ramp.
Make sure that the drive shows the correct indications.
Make sure that the emergency stop reset button indicator light [S62] comes on.
Make sure that the main contactor/breaker [Qx] opens.
Make sure that the drive generates none of these faults:
•STO hardware failure (5090)
•Safe torque off 1 loss (FA81)
•Safe torque off 2 loss (FA82)
If the drive generates these faults, see the fault tracing instructions in this manual.
Make sure that you cannot close the main contactor/breaker with the operating switch on the cabinet
door, or by other means.
Make sure that you cannot start the drive from any control location. Make sure that the drive does not
start when you switch the start signal off and on, or push the start key of the panel when the panel is
in local control mode.
Switch off the drive start signal.
Turn the emergency stop button until it releases and returns to the up position.
Push the emergency stop reset button [S62] to reset the emergency stop circuit.
Make sure that the emergency stop reset button indicator light [S62] goes off.
Power up the drive (see the hardware and firmware manuals).
Restart the drive and make sure that the drive and the motor operate normally.
