Overtorque Detection Function - Omron SYSDRIVE 3G3MV User Manual

Advanced Operation

6-7 Overtorque Detection Function

When an excessive load is applied to the equipment, the Inverter detects
the overtorque condition through an increase in the output current.

Value
0 Inverter does not monitor overtorque.
1 Inverter monitors overtorque only when speed is matched. It continues
operation (issues warning) even after overtorque is detected.
2 Inverter monitors overtorque only when speed is matched. It discontinues
operation (through protective function) when overtorque is detected.
3 Inverter always monitors overtorque during operation. It continues operation
(issues warning) even after overtorque is detected.
4 Inverter always monitors overtorque during operation. It discontinues
operation (through protective function) when overtorque is detected.
·Set n097 (overtorque detection function selection 2), n098 (overtorque detection level)
and n099 (overtorque detection time) to enable the overtorque detection function. The
Inverter will detect overtorque when the current is the same as or higher than the
detection level is output for the preset detection time.
·Set a multi-function output (n057 to n059) to either of the following so that external
overtorque detection output will be ON.
Set Value: 6 for overtorque detection (NO)
Set Value: 7 for overtorque detection (NC)

Note Overtorque detection will be canceled if the output current decreases from the detection level by approx-
imately 5% of the Inverter rated current.
