Three-phase motors
Connect the motor according to the
figure. When connected according to the
connection diagram, the motor will
operate in the clockwise direction (CW) as
viewed from the motor’s output shaft.
To change the direction of rotation,change
any two connections between R, S and T.

Connecting Protective Earth Terminal
Ground the motor using the motors with a Protective Earth Terminal .
Applicable crimp terminal:
Insulated round crimp terminal
Terminal screw size: M4
Tightening torque:
1.0 to 1.3 N·m (8.8 to 11.5 lb-in)
Applicable minimum lead wire size:
AWG18 (0.75 mm
2
) or more
Unit [mm (in.)]
Ø4.1 (0.16) min.
4.8 (0.19) max.
9.5 (0.37) max.
Note
Do not use screws other than the Protective Earth Terminal screws
attached on the product.
Time rating
Note
The continuous-operation time when operating the motors with the
speed controllers depends on the load, set speed and operating
cycle.

Induction motors
Induction motors have a continuous rating.

Reversible motors
Reversible motors have a 30 minutes rating. “30 min” is indicated on the
nameplate.
Locked rotor burnout protection
This motor is equipped with one of the two features listed below to prevent the
motor from burning out as a result of abnormal heating which may be caused by
misapplication.
Thermal protection
“TP” is stamped on the motor nameplate. The motor has an “auto reset”
type thermal protector built into its motor coil. When the motor reaches a
predetermined temperature, the internal thermal protector is activated and the
motor is stopped.
Always turn the power off before performing inspections.
Thermal protector activation range:
Power is turned off at 130±5 °C (266±9 °F)
Power is turned back on at 85±20 °C (185±36 °F)
Impedance protection
“ZP” is stamped on the motor nameplate. The motor has higher coil impedance.
When the motor goes into locked rotor condition due to a malfunction, coil
impedance rises, suppressing input power to the motor and protecting the motor
coil from burnout.
Troubleshooting
When the motor cannot be operated correctly, refer to the contents provided in
this section and take appropriate action. Refer also to the OPERATING MANUAL
for the speed controller. If the problem persists, contact your nearest office.
