Description
Sets the overtorque/undertorque detection level. 100% is
equal to the motor rated current in V/f Control or PM OLV
and equal to the motor rated torque in Open Loop Vector
Control.
Sets the length of time an overtorque/undertorque
condition must exist before torque detection 2 is
recognized by the drive.
L7: Torque Limit
Use L7 parameters to configure the torque limit function.
Sets the torque limit value as a percentage of the motor
rated torque. Four individual quadrants can be set.

L7-02
Sets the integral time constant for the torque limit.
Selects the method of torque limit control during accel/
decel.
0: Proportional Control (change to integral controls at fixed
speeds). Use this setting when acceleration to the desired
speed has priority over torque limitation.
1: Integral Control. Use this setting if the torque limitation
has priority.
When torque limit is applied to the motor, accel/decel time
may increase and motor speed may not meet the speed
reference.
L8: Drive Protection
Use L8 parameters to configure hardware protection functions.
Selects the Braking resistor when using a 3% duty cycle
heatsink mounted braking resistor. This parameter does not
enable or disable the braking transistor of the drive.
0: Resistor overheat protection disabled
1: Resistor overheat protection enabled
Sets the temperature for the heatsink overheat alarm oH.
If the heatsink temperature exceeds the value set to L8-02,
an output terminal set for the oH alarm (H2-
close.
Determines the action the drive should take when the
heatsink overheat alarm oH is triggered.
0: Ramp to Stop using the active decel time.
1: Coast to Stop.
2: Fast-stop using the time set in C1-09.
3: Alarm Only. Drive continues running, but displays an
alarm.
Settings 0 through 2 trigger a fault relay if the heatsink
becomes too hot.
Selects the detection of input current phase loss, power
supply voltage imbalance, or main circuit electrolytic
capacitor deterioration.
0: Disabled
1: Enabled
