Mechanical Weakening
(oL5) Detection Operation
This function can detect an over/undertorque in a certain
speed range as a result of machine fatigue. It is triggered by
a certain operation time and uses the oL1 detection settings
(L6-01 to L6-02)
0: Mechanical Weakening Detection disabled.
1: Continue running (alarm only). Detected when the speed
(signed) is greater than L6-09.
2: Continue running (alarm only). Detected when the speed
(not signed) is greater than L6-09.
3: Interrupt drive output (fault). Detected when the speed
(signed) is greater than L6-09.
4: Interrupt drive output (fault). Detected when the speed (not
signed) is greater than L6-09.
5: Continue running (alarm only). Detected when the speed
(signed) is less than L6-09.
6: Continue running (alarm only). Detected when the speed
(not signed) is less than L6-09.
7: Interrupt drive output (fault). Detected when the speed
(signed) is less than L6-09.
8: Interrupt drive output (fault). Detected when the speed (not
signed) is less than L6-09.

Mechanical Weakening
Detection Speed Level
Sets the speed that triggers mechanical weakening detection.
When L6-08 is set for an unsigned value, the absolute value
is used even if the setting is negative.

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.

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.

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

Overheat Pre-Alarm
Operation Selection
Sets the drive operation when an overheat alarm oH is
detected.
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.
4: Reduced Speed Operation. Drive continues to run with
reduced frequency reference as specified in L8-19.
Settings 0 through 2 trigger a fault relay if the heatsink
becomes too hot.
