For the speed sensorless vector control, this parameter is used to adjust the
speed stabilizing precision of the motor. When the speed is too low due to
heavy load of motor, this parameter needs to be enlarged or this parameters
needs to be reduced.
For the speed sensor vector control, this parameter can adjust the output
current of the driver carrying the same load.

In the vector control mode, the output of speed loop regulator is torque
current command. This parameter is used to filter the torque command. This
parameter needs no adjustment generally and this filter time can be
increased in case of huge speed fluctuation. In case of oscillation of motor,
this parameter shall be reduced properly.
The time constant of speed loop filter is low, and the output torque of the
driver may vary greatly, but the response is quick.

0: Torque control is inenabled, and the driver performs command speed
control. In case of speed control, the driver output frequency in accordance
with the setup frequency command, and the output torque automatically
matches the load torque, but the output torque is limited by the torque upper
limit (refer to F2-09 and F2-10). When the load torque is higher than the
setup torque upper limit, the output torque of the driver is limited, and the
output frequency will be different from the setup frequency.
1: Torque control is enabled, and the driver performs torque control. In case
of torque control, the driver outputs torque in accordance with the setup
torque command, and the output frequency automatically matches the load
speed, but the output frequency is limited by the frequency upper limit (refer
to F0-12). When the load speed is higher than the setup frequency upper limit,
the output frequency of the driver is limited, and the output torque will be
