<Precautions> 1. When SW2 and SW3 are switched from RUN to STOP, electric braking is applied for approx. 5 sec, or until the motor stops. (Do not operate SW4 and SW5 until the motor stops completely.) SW2 and SW3 must be operated simultaneously. Otherwise, abnormal operation occurs (full speed rotation for a short time), causing the motor temperature rises excessively. 2. Do not change the rotating direction (SW4, SW5) 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-20. 5. Insert R1 and C1 to protect relay contact. 6. R2 restricts discharge current in case of capacitor short circuit during braking.

6. Revolution speed 0 signal should not exceed 0.1 VDC. 7. The input speed pattern (curve) may not be exactly reflected on the motor speed, due to inertial effect of the load, especially during stop sequence. 8. The percentage ripple of analog voltage signal should be 2% or less. 9. For other wirings, refer to the corresponding circuit/wiring diagrams. 10. When using the braking feature, motor wiring (pins 1, 7 and 8) should be in accordance with pages C-8 and C-9. To activate braking, switch SW2 and SW7 at the same time. If SW2 is in RUN position while SW7 is in STOP, abnormal operation occurs (full speed rotation for a short time); or if SW7 is in RUN position while SW2 is in STOP, motor temperature rises excessively.
13 Operation through contactless signal
Small signal relays SW3, SW6 and SW7 can be replaced with transistor.
15 Parallel operation through analog signal
<Precautions> The input impedance of the controller is approx. 100 k. The output impedance of the analog signal source should be determined based on the total input impedance of the speed controllers.

14 Parallel operation through external speed changer
<Precautions> 1. The resistance Rs of the external speed changer VR should be as follows: Rs = 20/N (k) where, N is the number of motors. 2. For synchronous operation or ratio operation, desired revolving speeds must be set from the maximum speed control. Soft-start and soft-down controls and operation changeover switch must be set to the same position. 3. Wirings from the external speed changer VR should be connected to the same pins (No.5 and 6) on the controller. 4. Malfunction may occur as the number of devices operated in parallel increases. To secure correct operation, connect a noise filter to each unit. 5. For other electrical connections, refer to corresponding circuit/wiring diagrams.

16 Soft-operation

Soft-start, soft-down

<Precautions> 1. Power switch SW1 should be turned on approx. 0.5 sec before the operation start signal from SW6. 2. When repeating run/stop cycles, turn on/off only SW6 while keeping SW1 turned ON. In this way, the motor can be controlled by using a small signal. To stop operation for a long time, also turn off SW1. 3. Soft-start/soft-down period is the time required for the equipment to start up from stop state to full speed when the external speed changer is set at maximum value. 4. Soft-start/soft-down control, when at the full clockwise position, disables the soft-down function. As the stop signal is input, power supply to the motor is turned off immediately. However, the revolving speed gradually decreases in proportion to the inertia of the load and motor starts free-running stop sequence. 5. Soft-start/soft-down control can set maximum time length of approx. 5 seconds (Typ. at FCCW). The setting may be exceeded if the inertia of the load is too large. 6. For other electrical connections, refer to corresponding circuit/wiring diagrams.

6. Revolution speed 0 signal should not exceed 0.1 VDC. 7. The input speed pattern (curve) may not be exactly reflected on the motor speed, due to inertial effect of the load, especially during stop sequence. 8. The percentage ripple of analog voltage signal should be 2% or less. 9. For other wirings, refer to the corresponding circuit/wiring diagrams. 10. When using the braking feature, motor wiring (pins 1, 7 and 8) should be in accordance with pages C-8 and C-9. To activate braking, switch SW2 and SW7 at the same time. If SW2 is in RUN position while SW7 is in STOP, abnormal operation occurs (full speed rotation for a short time); or if SW7 is in RUN position while SW2 is in STOP, motor temperature rises excessively.
