Dismounting
WARNING
Do not work at running or unsecured installations.
Before starting to dismount, secure the machine against accidental move‐
ments and unauthorized operation.
Before dismounting them, secure the motor and the supply lines unit against
falling or movements, before unfastening the mechanical connections.
WARNING
Before beginning to work, let the motors cool down. The thermal time con‐
stant specified in the Technical Data is a measure for the time required for
cooling down. Cooling down can require up to 140 minutes!
Do not work at hot surfaces.
Wear safety gloves.
1. Observe the instructions contained in the machine documentation.
2. Observe the Safety Instructions and carry out all steps according to the
above instructions for "deactivation".
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.
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. Wait 30 minutes to allow the DC bus capacitors to discharge
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)
Via the interface X2 at KSM/KMS, you can "release" the integrated holding
brake.
