Entering motor parameters
Motor parameters
Motor parameters are specified by Rexroth and cannot be
changed by the user. If these parameters are not available, com‐
missioning is not possible! In this case, please contact your
Rexroth Sales and Service Facility.
WARNING
⇒ Do not switch on the motor immediately after entering the motor parame‐
ters
⇒ Enter the parameters for the encoder system
⇒ Check and adjust the encoder polarity
⇒ Configure the commutation settings
The motor parameters should be entered as follows:
●
Use DriveTop to load all motor parameters.
If the DriveTop commissioning software is not available, you have
to
●
enter the individual parameters manually via the controller. A
list of the corresponding motor parameters is available from
your sales partner.

Commissioning, operation and maintenance
Activation of the motor immediately after mo‐
tor parameter input may result in injury and
mechanical damage! The motor is not yet
ready for operation after the motor parame‐
ters have been entered!
