NOTICE
Risk of data loss!
When you reset parameters to the factory settings, all stored parameters and data
will be lost. Once the device has been reset to its factory settings, it must be
commissioned again.
● Make a copy of the working settings before you reset the variable speed drive
to its factory settings.
The communication settings and the settings of the motor standard (IEC/NEMA)
are retained after resetting.
Proceed as follows to reset the variable speed drive to its factory settings:
1. Go online with STARTER.

Setting the PID controller
If the PID controller is activated, the set ramp times are bypassed in p1120 and
p1121 (applies only to FW < V4.7 SP3).
● Therefore, define the following settings for smoothing times, ramp times and
controller.
