REXROTH IndraDrive Mi - Replacing KSM or KMS; Service Function Release Holding Brake; Saving Parameters

3. Before dismounting them, secure the motor and the supply lines unit
against falling or movements, before unfastening the mechanical con‐
nections.
4. Dismount the motor from the machine.
5. Store the motor appropriately.
Replacing KSM or KMS
In case servicing becomes necessary, the motor with the electronic system is
replaced by a new motor of the same type. This requires the following steps:
1. De-energize the machine (switch off 24V supply, too!)
2. WARNING! High electrical voltage! Danger to life by electric shock!
Before you start replacing KSM or KMS, wait 30 minutes to allow dis‐
charging.
3. Ensure isolation from supply
4. Dismount the defective KSM/KMS
5. Remove the MMC from the defective KSM/KMS at X7
6. Set the SERCOS address at the new KSM/KMS
7. Plug the removed MMC into the new KSM/KMS, mount the cover and
make sure the sealing ring is undamaged
8. Mount the new KSM/KMS and establish the electrical connections
9. Switch on 24V supply
10. Load the parameter set
11. Reestablish the position data reference (homing procedure)
Service Function "Release Holding Brake"
Via the interface X2, you can "release" the integrated holding brake.
To carry out this function, the 24V supply must have been applied.
Lethal injury caused by errors when control‐
ling motors and working at moving parts!
WARNING
● Do not work at running or unsecured installations.
● Before starting to dismount, secure the machine against accidental
movements and unauthorized operation.
● Before dismounting them, secure the motor and the supply lines unit
against falling or movements, before unfastening the mechanical con‐
nections.
For the purpose of commissioning and servicing, release the holding brake
via connection point X2 by connecting the contacts X2.1 and X2.2.
Saving Parameters
For servicing, the drive parameters must be saved and archived at initial
commissioning (e.g. with the software Rexroth IndraWorks D); this is neces‐
sary, because you won't probably be able to read the parameters of the de‐
fective drive.
Parameters can be administrated in the control unit or saved and loaded via
the RS232 interface (X2) and the software "Rexroth IndraWorks D".
