DIGIVEX Little Drive Servoamplifier

1.3.3.8 Monitoring reasons for stoppage

This monitoring may, through strategic choice, entail either stoppage or reduced performance for
certain faults related to current.
Variables monitored :
Mean drive current.
Output current (short-circuit).
Dissipater temperature.
Motor temperature.
Ambient temperature.
Overspeed.
No resolver.
Maximum and minimum dc bus voltages.
