Simplified Connection (Only single-phase motors)
Note : Wiring cannot be simplified for vertical drive applications or three-phase motors.
Connection can be simplified by using the connecting diagrams shown below when changing the swich RUN/STOP of the motor and the
electromagnetic brake by one swich.Using the connection shown below,however,results in a 50msec. increase in braking time over that of
the basic connection with a corresponding increase in overrun.The reason for this is that an electromagnetic energy of motor electromagnetic
brake, so that the electromagnetic continues to operate for about 50msec. even though the swich SW1 has been turned off.The brake thus
takes longer to engage.

Operation
Note : -Make sure that the motor case temperature does not exceed 90°C(194°F)during motor operation.
Operating the motor above 90°C(194°F)will shorten the life of the coil and the ball bearings.
Motor case temperature can be measured by fastening a thermometer to the motor’s surface, or with thermo-tape.
-Use the provided capacitor for single-phase motors and always keep the capacitor connected after the motor is started.

This Timing Chart is case of the basic connection.

Starting and Stopping
SW1 operates motor and electromagnetic brake action.
Motor will rotate when SW1 is switched simultaneously to ON( short circuit ). When SW1 is swiched simultaneously to OFF( open ), the motor
stops immediately by electromagnetic brake and holds the load.
Note : When operating the electromagnetic brake, this may make a friction noise because this is the braking system by friction, but this is
not a problem.
■
Direction of Rotation
［
Single- phase Motor
］
To rotate the motor in a clockwise(CW) direction, swich SW2 to CW.
To rotate it in a counter-clockwise(CCW) direction, swich SW2 to CCW.
［
Three- phase Motor
］
To change the direction of rotation, change any two connections between U, V and W.

Other ways of operating
・
Hastening the motor’s starting time
If the electromagnetic brake is left release, the motor can be started much faster.
Optimum timing for release of the brake is at least 10msec.before starting up the motor.
・
Releasing Electromagnetic brake
If you wish to release the brake while the motor is stopped, apply voltage between only two orange lead wires.
The electromagnetic brake is released and the motor shaft can be rotated easily by hand.
Note : When driving a vertical load,this method cannot be applied because this may cause the load to fall.
