L7-06: Torque Limit Integral Time Constant
■
Sets the integral time constant for the torque limit function. Decrease this setting to increase frequency fluctuation due to
torque limit while applying integral control.
No.
L7-06 Torque Limit Integral Time Constant
L7-07: Torque Limit Control Method Selection during Accel/Decel
■
Selects the function of torque limit during acceleration and deceleration.
No.
Torque Limit Control Method Selection during
L7-07
Setting 0: Proportional control (changes to integral control at constant speed).
The torque limit function works with P control during accel and decel, and switches to I control at constant speed. Use
this setting when accelerating or decelerating to the desired speed has priority over the torque limit during speed changes.
Setting 1: Integral control
The torque limit function always uses I control. Use this setting when a highly accurate torque limit is required, even
during speed changes. Using this function may increase the acceleration time, or may prevent the motor speed from
reaching the frequency reference if the torque limit is reached first.
L7-16: Torque Limit Process at Start
■
Assigns a time filter to allow the torque limit to build at start.
No.
L7-16
Setting 0: Disabled
Toque limit is created at start without a delay time. Disable L7-16 to maximize response time when the application
requires sudden acceleration or deceleration at start.
Setting 1: Enabled
A time filter is added to allow the torque limit to build at start.
■ L7-30: Regenerative Torque Limit Mode Selection
Parameter L7-30 sets the mode for the regenerative torque limit.
No.
L7-30 Regenerative Torque Limit Mode Selection
Setting 0: Standard mode (torque limits from all analog and communications inputs effective)
Setting 1: Independent mode (only L7-03, -04 and H3-
