Definition / explication of the signal Remark
12 (FIELD2_CURR_MIN_L) 1 = motor 2 field current above min level
11204 -- ---- TC_STATUS:
Status of the torque control sequencing
00 (RDY ON) 1 = ready for closing contractor
01 (MAIN CONT ON) 1 = command to close contractor
02 (RDY RUNNING) 1 = ready for run command
03 (RUNNING) 1 = command to release controllers
04 (TC_RDY_REF) 1 = ready for reference
05 (TC_FIELD_CHANGE) 1 = field reversal is active
06 (CONTINUOUS_CURR) 1 = armature current is discontinuous
11205 -- ---- 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
00 -------- Overcurrent
01 -------- Freewheeling unit was fired
02 -------- field reversal
03 -------- supply system undervoltage
04 -------- 12Puls only: fault 65 and 66 occurred
05 -------- 12Puls only: signal via cable X18
06 -------- supply system overvoltage
07 -------- type code error
08 -------- suppression of controller at regulator change-over
09 -------- processor overload
10 -------- thyristor diagnostic running
11 -------- --------
12 -------- primary (AC) or secondary (48Vdc) power failure
13 -------- synchronization signal missing
14 -------- pulse firing section not in synchronism
15 -------- not released
