Maintenance Operations

The motor only rotates in one direction.

The motor is rotating in the wrong direction.

The motor is burning out.

Problem

Probable cause

Correction

Reverse rotation prohi-
bition is selected.

If P13 (reverse rotation prohibit 
selection) is set to FWD (prohibit 
reverse operation), the Inverter 
will not accept reverse-rotation 
commands.

To use both forward and reverse rotation, set 
P13 to “F.R.”

Problem

Probable cause

Correction

The output wiring of the 
motor is faulty.

The U/T1, V/T2, and W/T3 termi-
nals of the Inverter are not prop-
erly connected to the U, V and W 
terminals of the motor.

When the U/T1, V/T2, and W/T3 terminals of 
the Inverter are properly connected to the U, V 
and W terminals of the motor, the motor will 
operate in a forward direction when a forward 
rotation command is executed. The forward 
direction depends on the manufacturer and the 
motor type. Therefore, be sure to check the 
specifications.Switching two wires among the 
U/T1, V/T2, and W/T3 will reverse the direction 
of rotation.

Problem

Probable cause

Correction

The load is too big.

If the load of the motor is too big 
and the motor is used with the 
effective torque exceeding the 
rated torque of the motor, the 
motor will burn out. 

Reduce the load amount by either reducing the 
load or lengthening the acceleration/decelera-
tion time. Also consider increasing the motor 
capacity.

Note: For example, the rated torque of the 
motor and capacity may be limited to eight 
hours of use if the inscription on the motor 
states that the motor is rated for eight hours. If 
the 8-hour rated torque is used for normal 
operation, it may cause the motor to burn out.

The ambient tempera-
ture is too high

The rating of the motor is deter-
mined within a particular ambient 
operating temperature range. The 
motor will burn out if it runs con-
tinuously at the rated torque in an 
environment in which the maxi-
mum ambient operating tempera-
ture is exceeded.

Lower the ambient temperature of the motor to 
within the acceptable ambient operating tem-
perature range.

The withstand voltage 
between the phases of 
the motor is insufficient.

When the motor is connected to 
the output of the Inverter, a surge 
will be generated between the 
switching of the Inverter and the 
coil of the motor. Normally, the 
maximum surge voltage is 
approximately three times the 
input power supply voltage of the 
Inverter (i.e., approximately 600 V 
for 200-V Inverters).

Therefore, the dielectric strength of the motor 
to be used must be higher than the maximum 
surge voltage.
