Notes on Commissioning
In the case of Rexroth motors without encoder data memory, the motor-
specific parameter values made available, such as
• motor parameters
• parameters of the measuring system
• parameters of the motor holding brake
• temperature sensor parameters
can either be input manually by means of a list (e.g. via the control
terminal) or loaded via the "DriveTop" commissioning tool from a data
base.

With values between 50% and 100% it is possible to obtain a compromise
between the mentioned effects!
It is therefore necessary to make sure you obtain the desired results for
processing or
premagnetization factor has been reduced!
Note: The selection lists for motor/controller combinations with
Rexroth asynchronous motors (2AD, ADF, 1MB, MAD, MAF),
published by Rexroth, refer to a premagnetization of 100%.
With lower values you have to expect deviation from these
data!
