6.1 Replace and repair
Repair:
The repair of the servo drive has to be done by the manufacturer.
Replace:
If a component of the servo drive system has to be replaced, notice
following checklist (no special mounting tools are required):
Switch off the main switch of the switchgear cabinet and remove the fuses
supplying the servo drive system
Wait at least 7 minutes after disconnecting the servo drive system from the
mains supply voltage before touching live sections of the equipment (e.g.
contacts) or undoing connections. Capacitors can still have dangerous volt-
ages present up to 7 minutes after switching off the supply voltages. To be
sure, measure the voltage in the DC-link circuit and wait until it has fallen
below 40 V.
During operation, the heat sink of components of the servo drive system
can become hot and may reach temperatures above 80 °C (176 °F). Check
(measure) the heat sink temperature and wait until it has cooled below
40 °C (104 °F) before touching it.
Remove the connectors. Make sure, that the identification is clear, not to
swap the connectors at installation of the replacement.
