L5-04 Fault Reset Interval Time
Sets the amount of time to wait between performing fault restarts. Enabled when
L5-05 is set to 1.

L5-05 Fault Reset Operation Selection
Selects the method of incrementing the restart counter.
0: Continuously attempt to restart and increment counter after successful restart
(like Varispeed VS616-F7/G7)
1: Attempt to restart with the interval time set in L5-04. Every trial increments
the counter. (like Varispeed VS606-V7)

L6: Overtorque Detection
Use L6 parameters to configure overtorque detection.
L6-01 Torque Detection Selection 1
Selects the overtorque/undertorque operation. overtorque and undertorque are
determined by the settings in parameters L6-02 and L6-03. The multi-function
output settings (H2-oo = B and 17) are also active if programmed.
0: Disabled
1: OL3 at Speed Agree - Alarm (overtorque detection only active during Speed
Agree and operation continues after detection).
2: OL3 at RUN - Alarm (overtorque detection is always active and operation
continues after detection).
3: OL3 at Speed Agree - Fault (overtorque detection only active during Speed
Agree and drive output will shut down on an OL3 fault).
4: OL3 at RUN - Fault (overtorque detection is always active and drive output
will shut down on an OL3 fault).
5: UL3 at Speed Agree - Alarm (undertorque detection is only active during Speed
Agree and operation continues after detection).
6: UL3 at RUN - Alarm (undertorque detection is always active and operation
continues after detection).
7: UL3 at Speed Agree - Fault (undertorque detection only active during Speed
Agree and drive output will shut down on an OL3 fault).
8: UL3 at RUN - Fault (undertorque detection is always active and drive output
will shut down on an OL3 fault).

L6-02 Torque Detection Level 1
Sets the overtorque/undertorque detection level. 100% is equal to the motor rated
current in V/f control and the motor rated torque in Open Loop Vector control.

L6-04 Torque Detection Selection 2
Sets the response to an overtorque/undertorque condition. overtorque and

L6-08
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 L6-03)
0: Mechanical Weakening Detection disabled.
1: Continue running if the speed (signed) is greater than L6-09 (alarm only).
2: Continue running if the speed (not signed) is greater than L6-09 (alarm only).
3: Interrupt drive output when the motor speed (signed) is greater than L6-09
(protection operation).
4: Interrupt drive output when the motor speed (not signed) is greater than L6-09
(protection operation).
5: Continue running if the speed (signed) is less than L6-09 (alarm only).
6: Continue running if the speed (not signed) is less than L6-09 (alarm only).
7: Interrupt drive output when the motor speed (signed) is less than L6-09
(protection operation).
8: Interrupt drive output when the motor speed (not signed) is less than L6-09
(protection operation).

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.
