		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
