than those given below. 

 

Abnormal Phenomenon 

Major Cause(s) 

Remedy 

Electric motor does not start even 
after turning switch to the “START” 
position. 

• Improper wiring and 

power supply error 

• Inverter panel circuit 

breakers are set to 
“OFF” position. 

• A break in stator 

winding 

• Check wiring according to 

“Engine & Electric Motor 
Spec. Operation”. 

• Set all circuit breakers to 

“ON” position. 

Inspection, repair, 

replacement 

Inspection, repair,

The motor comes to a stop during 
use. 

• Inverter unit error 
• Failure in the Inverter 

unit 

• Failure in the power 

unit 

• Check the power supply 

source (voltage and phase 
interruption). 

Inspection, repair, 

replacement 

Inspection, repair, 

replacement 

The power output of the motor 
reaches zero or undergoes gradual 
decrease. 

• Phase interruption in 

the power source of 
power supply 
equipment 

• Slack in motor wiring 

• Check the power source of 

power supply equipment 
(voltage and phase 
interruption). 

• Inspect connection with the 

motor Terminal block. 

Inspection, repair, 

replacement 

The cabtire cable rises in 
temperature. 

• Considerable voltage 

drop 

• Ensure that the power 

supply voltage of power 
supply equipment is at a 
specified value. 

• Replace the cabtire cable 

with one adhering to 
specifications. 

An abnormal noise and vibration are 
present in the power unit during 
operation. 

• A break in motor 

winding 

• Loose fixing bolts on 

the motor and pump. 

• Loose coupling fixing 

bolts 

• Impurities on the 

coupling 

• Clogging in the 

hydraulic oil tank 
strainer and element 

• Inspect the motor Terminal 

block.
