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.
￭ Other recommended settings
ABB recommends that you also set these parameters to improve the
safety of the application:
• minimum and maximum speeds (parameter group 30)
• maximum current, power and torque (group 30)
• acceleration and deceleration times
•
stall protection (parameters 31.24…31.28)
•
motor load curve (parameters 35.50…35.55)
•
motor cable protection (parameters 35.60…35.62)
For more information, see the drive firmware manual.
FSO module
If you use an FSO module (option +Q972 or +Q973) in the safety
system configuration, set the parameters according to the system
requirements. Example values are shown in this section.
You need the Drive composer pro PC tool to set the FSO module
parameters. You also need a password to be able to download the
configuration to the FSO module from Drive composer pro. For the
default password of the FSO module, see the applicable FSO module
user’s manual. For more information on the Drive composer pro PC
tool, see Drive composer start-up and maintenance PC tool user's
manual (3AUA0000094606 [English]).
Follow the configuration steps described in the applicable FSO module
user’s manual, chapter Configuration.
