4.1 Replace and Repair
Repair: Repair of the servo amplifier must be performed by the
manufacturer.
Replace: If a servo amplifier must be replaced, the following checklist must
be observed (no special mounting tools are 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 (e.g. 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 necessary to wait until the DC-link voltage is below 40 V.
During operation, the heat sink of the servo amplifier can reach
temperatures 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).
