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
zero, everything is OK. Otherwise different bits of
BC will indicate the reason for blocking the current
