Name

Motor overload trip

 

(electronic thermal relay function)

 ∗1

Description

The electronic thermal relay function in the inverter detects motor overheat due to overload or reduced cooling 
capability during constant-speed operation and pre-alarm (TH display) is output when the integrated value reaches 
85% of the 

Pr. 9 Electronic thermal O/L relay 

setting and the protection circuit is activated to stop the inverter output 

when the integrated value reaches the specified value. When running a special motor such as a multi-pole motor or 
multiple motors, provide a thermal relay on the inverter output side since such motor(s) cannot be protected by the 
electronic thermal relay function.

Check point

1. Check the motor for use under overload.
2. Check that the setting of 

Pr. 71 Applied motor 

for motor selection is correct.

 (Refer to page 98).

3. Check that stall prevention operation setting is correct.

Corrective action

1. Reduce the load weight.
2. For a constant-torque motor, set the constant-torque motor in 

Pr. 71 Applied motor

.

3. Check that stall prevention operation setting is correct.

 (Refer to page 74).

Name

Fin overheat

Description

If the heatsink overheats, the temperature sensor is actuated and the inverter trips.
The FIN signal can be output when the temperature becomes approximately 85% of the heatsink overheat protection 
operation temperature.
For the terminal used for the FIN signal output, assign the function by setting "26 (positive logic) or 126 (negative 
logic)" in 

Pr. 190 or Pr. 192 (output terminal function selection)

.

 (Refer to page 114).

Check point

1. Check for too high surrounding air temperature.
2. Check for heatsink clogging.

3. Check that the cooling fan is not stopped (Check that 

 is not displayed on the operation panel).

Corrective action

1. Set the surrounding air temperature to within the specifications.
2. Clean the heatsink.
3. Replace the cooling fan.

Input phase loss

Name

Input phase loss

 ∗

Description

This fault is output when function valid setting (=1) is set in 

Pr. 872 Input phase loss protection selection 

and one phase 

of the three phase power input is lost. 

(Refer to page 141).

It may function if phase-to-phase voltage of the three-phase power input becomes largely unbalanced.

Check point

Check for a break in the cable for the three-phase power supply input.
Check that phase-to-phase voltage of the three-phase power input is not largely unbalanced.

Corrective action

Wire the cables properly.
Repair a break portion in the cable.
Check the 

Pr. 872 Input phase loss protection selection 

setting.

Stall prevention

Description

If the output frequency has fallen to 1Hz by stall prevention operation and remains for 3s, a fault (E.OLT) appears and 
trips the inverter. OL appears while stall prevention is being activated.

Check point

Check the motor for use under overload.

 (Refer to page 75).

Corrective action

Reduce the load weight. Check the 

Pr. 22 Stall prevention operation level 

setting.

Brake transistor alarm detection

Description

When a brake transistor alarm has occurred due to the large regenerative energy from the motor etc., the brake 
transistor alarm is detected and the inverter trips.
In this case, the inverter must be powered off immediately.

Check point

Reduce the load inertia.
Check that the frequency of using the brake is proper.
Check that the brake resistor selected is correct.

Corrective action

Replace the inverter.
