F3-19 Torque reference UP/DOWN time
Setting 0.000~10.000s. This time is the time over which the torque rises from zero to 250% of
range motor rated torque.

The torque control function can control the motor torque directly. It can be used for open-loop tension
control, load balancing control, etc. Upon receiving the stop command in torque control mode, the
inverter will switch to the speed control mode and stop.
Torque control is only applicable to vector control, and PG vector control is recommended for torque
control at low speeds or in generating state.
 F3-13=0 means that the digital input 45 can switch from speed control to torque control. Refer to page 74.
F3-16 selects the source for limiting the speed for torque control.
F3-19 is used to reduce the sudden change of the torque command. If the motor vibrates in torque
control mode, increasing F3-19 can be considered.
In torque control mode, the REV indicator on the keypad shows the direction of the operating frequency.

F3-24 Flux-weakening regulator integral time
Setting
0.010~3.000s(only valid for vector control)
range
F3-21 ensures that the motor has a full pre-excitation and enough starting torque. The pre-excitation time
is normally 0.1~2.0s, and the larger the motor capacity, the longer the time.
F3-22: its value is better to be below the flux-weakening point. Either overhigh or overlow setting would
