4.5.1 Normal mode
The behaviour of the servo amplifier always depends on the current setting of various para-
meters (e.g. ACTFAULT, VBUSMIN, VELO, STOPMODE, see commissioning software's
online help).
The diagram below illustrates the correct functional sequence when switching the servo
amplifier on and off.

Fig.: Switching on and off under normal conditions
Servo amplifiers on which the “Holding brake” function has been enabled have a separate
procedure to switch off the inverted rectifier (see section in this chapter entitled “Motor hold-
ing brake”).
The drive is shut down safely using the safety function STO (STO1-ENABLE/STO2-EN-
ABLE).
