PMC-2 Instruction Manual

Exchanging the motor
• open main switch
• secure against switch-on
• for mechanical exchange of the SB motor, observe manufacturer’s instructions
CAUTION
Risk of accident due to unintended axis movements. For servo axes with
indirect track measuring system by motor encoder, the relation for
measurement is lost if the motor is exchanged!
Therefore the relation to the machine’s coordinate system has to be restored
after the exchange!
• for indirect recording of actual position values by the motor’s own measuring system, the relation
for measurement has to be restored:
- for motors with SINCOS encoders: see separate description
- for motors with resolver: usually no adjustment is necessary
Exchanging cables
• open main switch
• secure against switch-on
• for exchanging cables, observe manufacturer’s instructions
CAUTION
Risk of accident due to possibly fatal voltage.
Disconnect or reconnect power connectors of the cables only if the plant is in
voltage-free state!
Connect power connectors only if both ends are dry and clean!
If no ready commissioned cables from ELAU are used: Check the use of new
cables for compatibility with the connection plan of the machine manufacturer!
