• Excitation voltage is DC24V±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 Technol-
ogy 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˚o r smaller at ex-factory point.
• Permissible angular acceleration : 30000rad/s
10000rad/s 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.)
