Note 1. There is no manual release mechanism. When it is necessary to hand-turn the servo motor shaft for machine centering, etc.,
use a separate 24VDC power supply to release the brake electrically.
2. The value for initial ON gap at 20
(68
).
3. The brake gap will increase as the brake lining wears, but the gap is not adjustable. The brake life indicated is the number of
braking cycles after which adjustment will be required.
4. 24VDC of the internal power output for interface (VDD) cannot be used. Always use a separate power supply.
5. The above values are typical initial values and not guaranteed values.
6. 73B is not available for the HC-KF.
7. 524B to 7024B are not available for the HC-SF.
(1) Sound generation
Though the brake lining may rattle during operation, it poses no functional problem.
If braking sound occurs, it may be improved by setting the machine resonance suppression filter or
adaptive vibration suppression control in the servo amplifier parameters. For details, refer to the
servo amplifier instruction manual.
