Holding Brake Specifications
Excitation voltage should be 24VDC ± 10%
*1) Delay of DC cutoff in case a surge absorber is used.
The values in this table are representative (except the friction torque, releasing voltage and
excitation voltage). The backlash of the brake is factory-set to within ±1 degree.
