4.5 Switch on/switch off behaviour
4 Function Description
4.5.2 Fault condition
Fault condition 4- ][Funktion_Ein_Aus_Fehler
The behaviour of the servo amplifier always depends on the current set-
ting of various parameters (e.g. ACTFAULT, VBUSMIN, VEL0, STOP-
MODE, see commissioning software's online help).
The diagram illustrates the start-up procedure and the sequence of the
servo amplifier's internal control system in the event of a failure of one
or more phases of the mains voltage, when the standard parameters are
set.
 F16/F19 = Error messages for mains-BTB/input phase
 F05 = Error message for undervoltage)
