of 1 using the parameter menu.
Identifying motor data
Alarm A07991 is output for as long as the converter has still not identified the motor data.
You must switch on the motor (e.g. from the IOP) to identify the motor data. The frequency
converter switches-off the motor after the motor data identification has been completed.
Motor data identification for dangerous loads
Secure dangerous plant and system parts before starting the motor data identification, e.g.
by fencing off the dangerous location or lowering a suspended load to the floor.
You have completed the converter's basic commissioning.

Enable "Safe Torque Off" safety function

Requirements:
● Commission a CU240E-2 Control Unit.
● In the basic commissioning, you selected a setting for the interfaces in which two
terminals are reserved for a safety function.
The "Basic Safety" wizard guides you through the enabling of the "Safe Torque Off (Basic
Safety)" safety function in a maximum of 18 steps. Depending on the sources for "Safe
Torque Off", you can skip individual steps.
NOTICE
