Changing Overtorque and Undertorque Detection Levels Using an Analog Input
If parameter H3-09 (Analog Input A2 Function Selection) is set to 7 (overtorque/undertorque detection level),
the overtorque/undertorque detection level can be changed using the analog input A2 (refer to Fig 6.53).
Only the overtorque/undertorque detection level 1 can be changed using the analog input. Overtorque/under-
torque detection level 2 cannot be changed by an analog input signal.

 Motor Overload Protection
The motor can be protected from overload using the built-in electronic thermal overload relay function.
Related Parameters
* Factory settings depend on Inverter capacity. (The values shown are for a 200 V Class Inverter with 0.4 kW.)
Multi-Function Outputs (H2-01 to H2-03)
Setting Motor Rated Current (E2-01 and E4-01)
Set the rated current value on the motor nameplate in parameters E2-01 (for motor 1) and E4-01 (for motor 2).
This set value is the base current for the internal thermal overload calculation.
