Contents of this chapter
This chapter lists the parameters that you have to set for the ATEX-certified motor thermal
protection functions (options +L513+Q971 and +L514+Q971).
WARNING! In case of missing or inaccurate information, do not operate the motor
before you have made sure the parameter settings are correct.
Drive / inverter unit
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 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.
