Note These parameters cannot be changed during operation.
•
The overtorque detection function detects an excessive mechanical load from an increase in the out-
put current (or output torque).
•
The settings in the torque detection selection parameters (L6-01 and L6-04) determine whether over-
torque conditions will be detected and what kind of processing will be performed if a overtorque condi-
tion is detected.
L6-01/L6-04 Settings
Setting
Function
0
No overtorque detection
1
Detect only during speed agreement. Continue operation even after detection. (Minor fault)
2
Detect overtorque at any time. Continue operation even after detection. (Minor fault)
3
Detect only during speed agreement. Stop output after detection. (Fault)
4
Detect overtorque at any time. Stop output after detection. (Fault)
•
When overtorque detection is enabled, be sure to set the overtorque detection level (L6-02 or L6-05)
and the overtorque detection time (L6-02 or L6-05). An overtorque condition is detected when the cur-
rent exceeds the overtorque detection level for longer than the overtorque detection time.
•
The overtorque detection level settings depend on the control mode:
Open-loop or flux vector control:
Set as a percentage of the motor’s rated torque.
Normal V/f or V/f with PG control:
Set as a percentage of the Inverter’s rated output current.
•
Any of the following functions can be set in a multi-function output (H2-01, H2-02, or H2-03) to indicate
the fact that an overtorque condition has been detected.
Setting B:
Overtorque detection 1 (N.O.)
Setting 17:
Overtorque detection 1 (N.C.)
Setting 18:
Overtorque detection 2 (N.O.)
Setting 19:
Overtorque detection 2 (N.C.)
