6.7.1 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.
Devices which are equipped with a selected “Brake” function use a special sequence for
switching off the output stage (ð p.21).
The -AS- option can be used to switch off the drive via a positive-action (approved by the Trade
Liability Association) safety relay, so that personnel safety is ensured at the drive shaft (ð p.91).
