When torque control takes effect,
If T > T , output frequency will increase continuously until it reaI5000s upper
set load
frequency limit.
If T < T output frequency will decrease continuously until it reaI5000s lower
set load,
frequency limit.
Inverter can run at any frequency between upper and lower frequency limit only
T
load.
Torque control can be switI5000d to speed control, vice versa.
Switching by multifunctional terminal: For example, if torque control is enabled
(P0.00=2), torque setting source is FV, the value of multifunction terminal S5 is set to 20
(Disable torque control). When S5 is valid, control mode will switch from torque control to
speed control, vice versa.
When running at torque control mode, press STOP/RST, it will switch to speed control
automatically.
If torque setting is positive, inverter will run forward; otherwise it will run reverse.
Notice:
„ When running at torque control mode, the acceleration time has nothing to do with
P0.08.
„ The 100% of torque setting is corresponding to 100% of P3.07 (Torque limit).
For example, if torque setting source is keypad (PD.06=0), PD.07=80% and
P3.07=90%, then
Function Code
Pd.08
Actual torque setting = 80% (PD.07) * 90% (P3.07) = 72%.

When running at torque control mode, output frequency can be adjusted by changing
upper frequency limit.

Auto current limiting function is used to prevent inverter trip over-current from surge
current. It is especially useful for the applications with big load inertia or step change of
load. This function is always enabled during acceleration or deceleration period.
