nSetting Precautions
• When the torque limit function is operating, control and compensation of the motor speed is disabled
because torque control is given priority.
• When using the torque limit to raise and lower loads, do not carelessly lower the torque limit value, as this
may result in the motor falling or slipping.
• Torque limits using an analog input are the upper limit value (during 10 V or 20 mA input) of 100% of the
motor rated torque. To make the torque limit value during 10 V or 20 mA input 150% of the rated torque,
set the input terminal gain to 150.0 (%). Adjust the gain for multi-function analog input terminal A2 using
H3-10.
• The torque limit accuracy is ±5% at the output frequency of 10 Hz or above. When output frequency is less
than 10 Hz, accuracy is lowered.

K Preventing Motor Stalling During Operation
Stall prevention during operation prevents the motor from stalling by automatically lowering the Inverter's
output frequency when a transient overload occurs while the motor is operating at a constant speed.
Stall prevention during operation is enabled only during V/f control. If the Inverter output current continues to
exceed the setting in parameter L3-06 for 100 ms or longer, the motor speed is reduced. Set whether to enable
or disable deceleration time using parameter L3-05. Set the deceleration time using C1-02 (Acceleration time
1) or C1-04 (Acceleration Time 2).
If the Inverter output current reaches the set value in L3-06 - 2% (Inverter Rated Output Current), the motor
will accelerate again at the frequency set or the acceleration time set.

*The initial value when C6-01 is set to 1 is given. If C6-01 is set to 0, the initial value will be 150%.
