Normal/reverse rotation and electric brake
4
<Precautions>
1. When SW3 and SW5 are moved from RUN to STOP, electric braking operates for approx. 0.5 sec causing
the motor to stop immediately. (Do not operate SW6 and SW7 until the motor stops completely.)
SW3 and SW5 must be turned on/off simultaneously. Otherwise, abnormal operation occurs (full speed
rotation for a short time), causing the motor temperature to rise excessively.
2. Never change the direction of rotation (CCW/CW, 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-27.
5. Insert R1 and C1 to protect relay contact.
6. R2 restricts discharge current in case of capacitor short circuit during braking.

Wiring of cooling fan motor (F) or motor with thermal protector (TP)
5
<Precautions>
1. The thermal protector (TP) is an automatic reset type. To prevent hazards caused by restarting, connect
the TP as shown above. Don't connect TP directly to the power supply.
2. Once the TP operates, cooling period is required before the operation can restart.
3. Connect the cooling fan motor (F) across pins 1 and 2 on the power terminal.
4. Motor (M) and tachometer generator (TG) should be connected according to corresponding wiring
diagram shown later.
Wiring to electromagnetic brake
6
<Precautions>
1. Operate SW9 simultaneously with RUN/STOP (BRAKE) switching of other switches, if any.
Placing other switches to RUN position while the brake is active (SW9 at STOP position) causes the
motor to generate heat.
2. For remaining wirings, refer to corresponding wiring diagram.
• Variable speed motor with
electromagnetic brake
should be wired as shown
below.
