4.1 Exchange and Repair
Repair:
of the servo amplifier must be performed by the manufacturer.
Exchange:
If a servo amplifier must be exchanged, the following points must
be observed (no special tools required):
Turn off the control cabinet supply and remove the servo amplifier fuses.
After disconnecting the servo amplifier from the main voltage supply, a wait-
time of 5 minutes is required before current-conducting components in the
amplifier (i.e. contacts) can be touched or connectors removed. Capacitors
can contain dangerous voltages for up to 5 minutes after the supply voltage
is removed. It is recommended to wait until the voltage in the intermediate
circuit is below 40 V.
During operation, the heat sink of the servo amplifier can reach tempera-
tures of over 80° C (176° F). The heat sink temperature should be checked
before handling and it may be necessary to wait until it is below 40° C (104°
F).
