Holding brake
The brake is to hold the work (movable part coupled to a vertical motor axis) to
prevent it from falling by gravity in case the servo power is lost.
<Caution>
The holding brake is to hold the work, not stop its
m o t i o n . N e v e r u s e t h e b r a k e f o r d e c e l e r a t i n g a n d

Driver
<Notes and Cautions>
1. The brake coil has no polarities.
2. The power supply for the brake should by supplied by the customer. Do not use the control
power (VDC) for driving the brake.
3. Install a surge absorber per the figure above in order to suppress the surge voltage due to
the on/off operation of the relay (RY). If you use a diode for surge absorber, note that the
start of the servo motor after releasing the brake is delayed.
4. Use the recommended surge absorber. See Recommended Parts in page 84.
