3-4. Wiring method when inverter is used
When the inverter drives the motor it is necessary to use a separate power supply for the brake. When using
a separate power supply for the brake, first remove the short piece, and then apply the normal power source
to the brake. Do not output power from the inverter.
For motors up to 0.4kW/ 400V class, remove the wire from the mid-tap and insulate it, and apply 200 to 220V
to the DC Module for the brake. In case a power source of 200 to 220V is not available, use a transformer to
step-down the voltage to the necessary 200 to 220V. The capacity of the transformer should be 90VA and
bigger, with no voltage drop.
Use a rated load of AC250V, 7A and larger for the electro-magnetic switch of the 200V class brake. Use a
contact voltage of AC400 --- 440V, with an inductive load of 1A and larger (ex. magnetic contactor for 2.2kW
motor) for the 400V class brake.
The DC Module has a surge absorption protective device. Add necessary protective devices to each contact
site.
If separate DC wiring is required, please contact us.
※
Special Type may require a different wiring. Please refer to the drawing.

Brake
0.2 to 0.4 kW
It is usually sufficient to monitor the operational status of the brake on your own, but please be aware of the
following:
The brake lining becomes worn because of the force of friction between the brake plate and
the lining. It is necessary to change the lining after 2 wear adjustments due to weak braking.
It is necessary to clean up the brake twice a year because it accumulates a lot of dust and
particles due to the continuous wearing of the brake lining.
