TC_STATUS
Signal of MAINTENANCE function.
Status of the torque control sequencing:
(internal signal; not shown on the panel; definition)
B0 (RDY ON
B1 (MAIN CONT ON
B2 (RDY RUNNING
B3 (RUNNING
B4 (TC_RDY_REF
B5 (TC_FIELD_CHANGE
B6 (CONTINUOUS_CURR

BC
Signal of MAINTENANCE function.
Status of the current contoller. If the value of BC is zero, everything is OK. Otherwise
different bits of BC will indicate the reason for blocking the current contoller:

SQUARE_WAVE
Signal of MAINTENANCE function.
Output of square wave generator. Used for tuning of controllers.
11206 S: I2 SC: -
TEST_REF
Signal of MAINTENANCE function.
Test reference input for different drive functions which are activated with DRIVE_MODE
parameter.
11207 S: I2 SC: 1
TEST_RELEASE
Signal of MAINTENANCE function..
Release-command for a controller in manual tuning of current or EMF controller. In
manual tuning first the reference is selected with the signal TEST_REF_SEL and then the
controller is released by setting TEST_RELEASE to a value different than zero.
