Parameters
Modifying the torque characteristics in the constant output area (Pr. 803)
● Because of the motor characteristics, torque is reduced at base frequency or higher. To generate
a certain amount of torque at base frequency or higher, use Pr. 803 "Constant output range torque
characteristic selection" = "1 or 11".
● Under torque control, the torque generated in the low-speed range is constant regardless of
Pr. 803 setting.
Pr. 803 setting
0 (initial value), 10
1, 11

Reverse selection of the torque command (Pr. 1114)
Whether the torque command polarity is reversed or not when the reverse rotation command (STR)
is turned ON can be selected using Pr. 1114 "Torque command reverse selection".
