Normal/reverse rotation and electric brake

When SW3 and SW5 are switched from RUN to

STOP, electric braking is applied for approx. 5

sec, or until the motor stops. (Do not operate

SW6 and SW7 until the motor stops completely.)

SW3 and SW5 must be operated

simultaneously. Otherwise, abnormal operation

occurs (full speed rotation for a short time),

causing the motor temperature to rise

excessively.

2. Do not change the rotating direction (SW6,

SW7) while the motor is running.

3. The number of start/stop cycles must be 6/min.

or less.

4. When using cooling fan motor or motor with

thermal protector, also see page C-35.

5. Insert R1 and C1 to protect relay contact.

6. R2 restricts discharge current in case of

capacitor short circuit during braking.

Connect a fixed resistor (R3) in place of external

speed changer (VR).

Even if the R3 is not used (connection across pins

3 and 6 are open), the speed can be adjusted from

the maximum speed control within its adjustable

range (not full range but almost by half).

SW1 : Power switch

SW3 : Braking start switch

SW5 : RUN/STOP switch

SW6,SW7 : Normal/reverse selector switch

• When no external speed changer is required,

the speed can be adjusted from the maximum

speed control.

Unidirectional rotation and electric brake

1. When SW3 and SW5 are switched from RUN to

STOP, electric braking is applied for approx. 5

sec, or until the motor stops.

SW3 and SW5 must be operated simultaneously.

Otherwise, abnormal operation occurs (full speed

rotation for a short time), causing the motor

temperature to rise excessively.

2. The number of start/stop cycles must be 6/min.

or less.

3. When using cooling fan motor or motor with

thermal protector, also see page C-35.

4. Insert R1 and C1 to protect relay contact.

5. R2 restricts discharge current in case of

capacitor short circuit during braking.

Connect a fixed resistor (R3) in place of external

speed changer (VR).

Even if the R3 is not used (connection across pins

3 and 6 are open), the speed can be adjusted from

the maximum speed control within its adjustable

range (not full range but almost by half).

SW1 : Power switch

SW3 : Brake start switch

SW5 : RUN/STOP switch

• Connection according to this wiring diagram

causes the motor to rotate clockwise when

viewed from the motor shaft end. To run the

motor counterclockwise, interchange the

connecting point of black and gray leads.

• When no external speed changer is required,

the speed can be adjusted from the maximum

speed control.
