Behavior in standard operation

The behavior of the servo amplifier always depends on the current setting of a number of different
parameters (e.g., ACTFAULT, VBUSMIN, VELO, STOPMODE, etc.; see online help). The diagram
below illustrates the correct functional sequence for switching the servo amplifier on and off.
DC bus link
Motor speed
Power stage
Enable (internal)
Devices which are equipped with a selected "Brake" function use a special sequence for switching
off the output stage (ð p. 21).
The built-in restart lock -AS- can be used to switch off the drive via a positive-action (approved by
Trade Liability Association) safety relay, so that personnel safety is ensured at the drive shaft
(ð p. 69).
