5.2.5.3. Wiring Example for YS Series Motor Equipped with Brake
l The brake built-in the YS series Motor is an electromagnetic brake that is released when the coil is
exited (negative action type). The brake is non-backlash type when it engages.
l The brake may be used for safety in case of unexpected power shutdown, or to provide extra-
holding torque when the Motor is on hold.
l Use an optional brake power supply because the brake is to be operated by the overexertion,
switching full-wave or half-wave rectification. (full-wave rectification for overexertion, while
half-wave rectification for holding).
Reference number of optional power supply: M-FZ063-1

Caution : • The brake output of the ESA type Driver Unit cannot be used to switch the
brake directly ON or OFF. For this purpose, be sure to use the brake switch
contacts externally.
• For brake on/off, use contacts with a capacity of more than 10 times of the
inductive load current at 180 VDC
• Do not short-circuit No.4 and No.5 terminals with power on.
• Be sure to use No.6 and No.7 terminals to turn on/off the brake.
• Never open/close No.6 and No.7 terminals in AC power side.
