Brake life (Note3)
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 .
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.
