Notes:
1. There is no manual release mechanism. If handling is required such as during the machine core alignment
work, prepare a separate 24 VDC power supply, and electrically release the brakes.
2. These are the values added to the servomotor without brakes.
3. This is the value for 20°C at the initial attraction gap.
4. The brake gap will widen through brake lining wear caused by braking. However, the gap cannot be adjusted.
Thus, the brake life is reached when adjustments are required.
5. The internal power output (VDD) 24 VDC for digital output cannot be used. Always prepare a separate power
supply.
6. A leakage flux will be generated at the shaft end of the servomotor with magnetic brakes.
7. When operating in low speed regions, the sound of loose brake lining may be heard. However, this is not a
problem in terms of function.
