Display Fault Description
Occurs when the intermediate circuit voltage rises
above the permissible value.
Occurs when the output voltage exceeds the permissible
value.
Occurs when the servo motor exceeds the permissible
operating temperature.
Is triggered by the internal motor current surveillance.
Function of an electronic protective motor relay.
Occurs when the digital input I3 is activated at
CP.15 = 0.
Is indicated in case of missing supply voltage to the
resolver.
Occurs when no defined power cicuit is recognized
Occurs when the intermediate circuit voltage drops
below the permissible value.
Hybrid error
Processor error
Overload
