4.5 Switch on/switch off behaviour
4 Function Description
4.5 Switch on/switch off behaviour 4500 Switch on/switch off behaviour 4- ][Funktion_Ein_Aus_Allg
This section describes the behaviour of the servo amplifier when switch-
ing on and off. It explains the measures that are required to achieve
compliance with the standards when a stop or E-STOP is performed
during operation.

software's online help
Behaviour during a power failure
The servo amplifier detects the failure of one or more input phases.
The behaviour of the servo amplifier is set using the commissioning soft-
ware: In the “Basic Setup” window, under “Response to Loss of Input
Phase”, select (PMODE):
` A warning appears if the higher level control system is intended to
bring the drive to a standstill:
A message indicates that an input phase is missing (message “n05”)
and the motor current is limited to 4 A. The servo amplifier is not
switched off. The higher level control system can now either end the
current cycle specifically or bring the drive to a standstill. The error
message “NETZ-BTB, F16”, for example, is sent to a digital output on
the servo amplifier and is evaluated by the control system.
` An error message appears if the servo amplifier is intended to bring
the drive to a standstill:
A missing input phase is registered as an error (error message “F-
19”). The servo amplifier is switched off; the BTB relay contact for op-
erational readiness opens. If the factory default setting is unchanged
INFORMATION
The servo amplifier's 24 VDC supply must be maintained even
after a stop or emergency stop.
The parameters ACTFAULT (reaction to fault) and STOPMODE
(reaction to ENABLE signal) define how the drive behaves when
it is switched off.
