K Motor Overload Protection
You can protect the motor from overload using the Inverter's built-in electronic thermal overload relay.
nRelated Parameters
* 1. Factory settings depend on Inverter capacity. (The values shown are for a 200 V Class Inverter for 0.4 kW.)
*2.The settings range is 10% to 200% of the Inverter rated output current. (The values shown are for a 200 V Class Inverter for 0.4 kW.)

Motor protection selection
Set to enable or disable the motor overload protec-
tion function using the electronic thermal relay.
0: Disabled
1: General motor protection
2: Inverter special motor protection
3: Vector motor protection
With applications where the power supply is often
turned ON and OFF, there is a risk that the circuit
cannot be protected even if this parameter has
been set to 1, as the thermal value will be reset. If
multiple motors are connected to one Inverter, set
this parameter to 0, and install a thermal relay in

Motor protection time con-
stant
Set the electronic thermal detection time in min-

Normally, there is no need to make this setting.
The factory setting is resistance at 150% for 1 min.
If the motor overload resistance is clear, set the
overload resistance protection time during hot
start to suit the motor.
