13 S_TLC Limiting torque
When the torque reaches the torque limit value during torque generation, S_TLC will turn on. This will be
turned off at servo-off.
The Status DO cannot be used in the torque mode.
14 S_ABSV Absolute position undetermined
1: Absolute position is erased
15 S_BWNG Battery warning
