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.

Note: If the value set with H (stall prevention level) is smaller than the torque limit, then the value set with
H acts as the torque limit.
