Problem
The motor does not rotate
or

exceeds 90°C (194°F) )
The motor makes a strange noise
Things to check
q
Is the correct voltage being supplied to the Motor?
w
Are lead wires properly and firmly connected?
e
Is the load too large?
r
If lead wires have been extended by using a terminal strip or terminal block, are the lead
wires properly and firmly connected at all points?
t
For a single-phase motor, is the provided capacitor connected as shown in the wiring
diagram of page 4?
y
Is voltage applied to the brake lead wires?
q
Are lead wires properly and firmly connected?
w
If lead wires have been extended by using a terminal strip or terminal block, are the lead
wires properly and firmly connected at all points?
e
For a single-phase motor, is the provided capacitor connected as shown in the wiring
diagram of page 4 ?
q
Is the connection as shown in the wiring diagram? Check the wiring diagram of page 4
again.
w
The gearhead output shaft
ﾕ
s rotation direction differs depending on the gearhead
ﾕ
s
deceleration ratio. Refer to the gearhead operation manual.
e
For a single-phase motor, is the provided capacitor connected as shown in the wiring
diagram of page 4 ?
r
Are you looking at the motor from the wrong side?
Rotation is defined as viewed from the output shaftside.
q
Is the correct voltage being supplied to the motor?
w
Does the ambient temperature exceed the permissible range ( +50°C(122°F) )?
e
For a single-phase motor, is the provided capacitor connected as shown in the wiring
diagram of page 4 ?
q
Are the motor and gearhead correctly fastened? Refer to the gearhead operation manual.
w
Is the coupled gearhead the same pinion type as the motor shaft?
