Customer needs to prepare.
- This diagram shows cases for motors with standard Japanese domestic specifications. Please consult with us for motors with overseas
specifications.
- For brake types, see Table 1-1 on P5.
- Use with a quick braking circuit. For information on electromagnetic contactors for quick braking circuits, see Table 6-4 on P37.
Rectifiers are external to the main unit. Rectifiers are made for indoor use. Install in an area where they will not come into contact with
water, etc.
- Brake unit is for 200V class. For 400V class power sources, prepare a 400V/200V transformer.
- Always use the inverter’s power source side for the brake power source.
- Match the opening and closing of the brake circuit’s electromagnetic contactor to the timing of the inverter control.
For AF motor for inverter with axial flow fan (fully enclosed separate ventilate type), note the following points.
- Connect electric power to an axial fan as well.
- In the case of 400 V class indoor equipment, the power source voltage for the axial fan is 200 V.
- In the case of special specifications, the actual product may sometimes differ from the above drawing, so check the manufacturing
specifications.
- Connect the fan so that it rotates in the direction indicated on the nameplate.
(When the fan is operating normally, it should blow cooling air from the non-load side to the load side.)
- When leaving the motor stopped for a long period, leave the axial fan motor stopped as well.
- A thermostat has been installed, so connect the wiring to it.
