L7: Torque Limit
Use L7 parameters to configure the torque limit function.
L7-01 Forward Torque Limit Sets the torque limit value as a percentage of
the motor rated torque. Four individual
quadrants can be set.

Torque Limit Control
Method Selection
during Accel/Decel
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: Hardware Protection
Use L8 parameters to configure hardware protection functions.
L8-01
Internal Dynamic
Braking Resistor
Protection Selection
(ERF type)
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

L8-02 Overheat Alarm Level
When the heatsink temperature exceeds the
value set in this parameter, an Overheat Alarm
(OH) will occur.
