10 Maintenance, Decomissioning, and Disposal
10.1 Warnings
W A R N I N G
HIGH VOLTAGE
Potentially lethal voltage is present on the connectors that may lead to death or serious injury.
Before working on the power or signal connectors (disconnecting or connecting the cable), or performing any maintenance
work, disconnect the Power Supply Module (PSM 510) from the mains and wait for the discharge time to elapse.
W A R N I N G
DISCHARGE TIME
The servo system contains DC-link capacitors that remain charged for some time after the mains supply is switched off at the
Power Supply Module (PSM 510). Failure to wait the specified time after power has been removed before performing service or
repair work could result in death or serious injury.
To avoid electrical shock, fully disconnect the Power Supply Module (PSM 510) from the mains and wait for the capacitors to
fully discharge before carrying out any maintenance or repair work on the servo system or its components.
Minimum waiting time (minutes)

10.2 Maintenance Tasks
The ISD 510/DSD 510 servo drives are largely maintenance free. Only the shaft seal on the ISD 510 (if used) is subject to wear. The
maintenance tasks must be performed by qualified personnel. No other tasks are required.

Maintenance interval Instruction
Servo drive
Carry out a visual inspection.
Every 6 months
Check for any abnormalities on the surface of
the servo drive.
Shaft seal on the ISD
510
Check the condition and
check for leakage.
Every 6 months
(1)
If damaged, replace the shaft seal.
Flange connection on
the ISD 510
Measure the resistance.
Every 12 months.
Measure the resistance of the flange connec-
tion on the ISD 510.
Hybrid cable
Check for damage and wear.
Every 6 months
If damaged or worn: Replace the hybrid ca-
ble.
Mechanical holding
brake (optional)
Check the brake.
Every 6 months
Ensure that the brake can achieve the hold-
ing torque.
Functional safety
Perform a system power cycle
and check the STO function.
Every 12 months
Activate STO and check the status with the
PLC.
System modules
Check the fan.
Every 12 months
Check that the fan can turn and remove any
dust or dirt.
Carry out a visual inspection
Every 6 months
Check for any abnormalities on the surface of
the module.
