". The value at torque control mode switching request is
valid for "

".
The command torque during torque control mode is limited with "
Pr.17 Torque limit
setting value
". If the torque exceeds torque limit setting value is set, a warning
"Torque limit value over" (warning code: 520) will occur, the operation is controlled
with torque limit setting value.
Confirm the command torque to servo amplifier with "
Md.123
