• Excitation voltage is DC24±10%.
• * Values represent the ones with DC-cutoff using a surge absorber for holding brake.
Values in ( ) represent those measured by using a diode (V03C by Renesas Technology Corp.)
• Above values (except static friction torque, releasing voltage and excitation current) represent typical
values.
• Backlash of the built-in holding brake is kept ±1˚ or smaller at ex-factory point.
• Permissible angular acceleration : 30000rad/s
• Service life of the number of acceleration/deceleration with the above permissible angular acceleration is
more than 10 million times.
(Life end is defined as when the brake backlash drastically changes.)
