Armature (DC circuit) overvoltage
Check: - Setting of param. [
for the system configuration?
- Setting of field current and actual
value as well as the complete
field supply (FIELD EXCITER);
- Was the motor accelerated by
the load?
- Speed scaling;
- Armature voltage feedback;
- Connections between SDCS-
CON-x and SDCS-PIN boards;
- Coding of voltage evaluation on
SDCS-PIN-xx board.
Mains supply undervoltage (AC)
parameter
[P 509]
Check: - Does the supply voltage exist?
- Did the mains contactor close?
- Setting of voltage feedback
coding (voltage scaling) correct?
- Connections between SDCS-
CON-x and SDCS-PIN-xx boards;
- Coding of voltage evaluation on
SDCS-PIN-xx board.
Mains supply overvoltage (AC)
Mains voltage > 130% of nominal value for
longer than 10s.
Fault tracing see Fault Code
Synchronization fault
Check: - Mains supply, fuses etc.;
- Mains voltage and stability.
FIELD EXCITER 1 (field supply 1) overcurrent
Check: - Parameters of
- Connections of field exciter as
well as insulation level of cable
and of field winding.
FIELD EXCITER 1 communication error
Check: - Flat cable connections X14: or
cable X16: between SDCS-
CON-x board and field exciter;
- Auxil. voltage for ext. field exciter.
