Maintenance and Repair
9-2 Operating Manual: PMCtendo AC
Maintenance intervals
If suitably installed, the servo motors are largely maintenance free. As operating
conditions can vary greatly, maintenance intervals must be adapted to suit the local
conditions (e.g. pollution degree, switch on frequency, load).
Maintenance interval
Regularly
Every 500 operating hours,
or
min. once per year
Every 2500 operating hours,
or
min. once per year
After 20000 operating hours
(under rated conditions)
What to consider?
Cleaning intervals should depend on
the local pollution degree
• Let the motor cool down
• Do not use solvents
• Select a cleaning method that’s
appropriate for the servo motor’s
protection type, otherwise the
ingress of liquid could damage the
motor.
