Unidirectional rotation and electric brake
3
• 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.
<Precautions>
1. When SW2 and SW3 are switched from RUN to STOP, electric braking is applied for approx. 0.5 sec, and
the motor stops instantly.
Difference in switching time between SW2 and SW3 must be 0.1 sec or shorter. If SW2 (SW3) is in RUN
position while SW3 (SW2) is in STOP, abnormal operation occurs (full speed rotation for a short time) and
motor temperature rises excessively.
2. The number of start/stop operations must be 6/min. or less.
3. For motors for cooling fan and motors with thermal protector, also refer to page C-12.
4. The spark killer consisting of R1 and C1 must be used to protect the relay contacts.
5. R2 limits flow of discharging current upon short-circuiting of the capacitor during braking.
Normal/reverse rotation and electric brake
4
<Precautions>
1. When SW2 and SW3 are switched from RUN to STOP, electric braking is applied for approx. 0.5 sec,
and the motor stops instantly. (Do not operate SW4 and SW5 until the motor stops.)
Difference in switching time between SW2 and SW3 must be 0.1 sec or smaller. If SW2 (SW3) is in RUN
position while SW3 (SW2) is in STOP, abnormal operation occurs (full speed rotation for a short time)
and motor temperature rises excessively.
2. Do not change the motor rotating direction (SW4, SW5) while the motor is running.
3. The number of start/stop operations must be 6/min. or less.
4. For motors for cooling fan and motors with thermal protector, also refer to page C-12.
5. The spark killer consisting of R1 and C1 must be used to protect the relay contacts.
