Using parameters, four different torque limits can be set for each operating status: power running and
regenerative braking. Refer to Section 7.2.1 for the setting for switching from the terminal board.
Power running torque limit 1 –  Regenerative braking torque limit 1 – 
Power running torque limit 2 –  Regenerative braking torque limit 2 – 
Power running torque limit 3 –  Regenerative braking torque limit 3 – 
Power running torque limit 4 –  Regenerative braking torque limit 4 – 
Note: If the value set with  (stall prevention level) is smaller than the torque limit, then the value set with
 acts as the torque limit.

The torque limits can be changed arbitrarily by means of external signals.
