Switching frequency limitation

The certificate of the Ex motor typically requires that you set a minimum limit for the switching
frequency of the drive.
For ABB Ex motors, use parameter 95.15 to set the required minimum switching frequency.
For more information, see the drive firmware manual.
For Ex motors supplied by other motor manufacturers, contact the motor manufacturer for
the correct value and your local ABB representative for instructions on how to make the
parameter setting in the drive.

Reset method and status indications

To configure a manual reset for the temperature protection function in the drive, you can
set either the STO indication (parameter 31.22 STO indication run/stop) or the motor
temperature indication so that it generates a fault.

31.22 STO indication run/stop

Set this parameter to value Fault/Fault or Fault/Warning.
• Fault/Fault: This generates a fault in the drive/inverter unit when STO is activated.
• Fault/Warning: This generates a fault in the drive/inverter unit when the drive is running
and warning when the drive is stopped.
