Specifications of Built-in Holding Brake

• 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/s2 for MAMA series

10000rad/s2 for MSMD, MQMA, MSMA, MDMA, MHMA, MFMA and

MGMA series

• 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.)
