1 = motor 2 field current above min level
---- TC_STATUS:
Status of the torque control sequencing
1 = ready for closing contractor
1 = command to close contractor
1 = ready for run command
1 = command to release controllers
1 = ready for reference
1 = field reversal is active
1 = armature current is discontinuous
---- BC:
Status of the current regulator. If the value of BC is
zero, everything is OK. Otherwise different bits of
BC will indicate the reason for blocking the current
regulator
Overcurrent
Freewheeling unit was fired
field reversal
supply system undervoltage
12Puls only: fault 65 and 66 occurred
12Puls only: signal via cable X18
supply system overvoltage
type code error
suppression of controller at regulator change-over
processor overload
thyristor diagnostic running
--------
primary (AC) or secondary (48Vdc) power failure
synchronization signal missing
