BRAKE PACK is a electronic braking circuit to stop single and three phase motor instantaneously. Applicable to inching, etc, since it can give a dynamical braking function at short cycle.

■ Cautions of connection

1. Connections differ with types and output power of the motors.

• Connect like diagram A for motor of output power 25W or less.

• Connect like diagram B for motor of output power 40W to 60W.

• If the motor's output is as follows; induction motor for 90W and reversible motor for

2. Be careful since there is high voltage on some terminals.

I, Connections differ with types and output power of the motors.

• Connect like diagram A for motor of output power 25W or less.

• Connect like diagram B for motor of output power 40W to 60W.

• B connection and external braking resistor with external resistance of 50Q 20W Is required for motors over 60W, 2 Be careful since there is high voltage on some terminals.

■ Cautions of connection

1. Connection of brake pack is different according to the output and usage of motors. • Connect like diagram A for motor of output power 40W or less,

■ In case motor of output torque more than 60W, need diagram B + braking external resistance 30Q 20W. Even though motor of output torque is less than 40W, If bracking is done in short cycles(more than 1 breaking per 5sec), Please use diagram B and connect external resistor for braking.

2. Be careful since there is high voltage on some terminals.

Caution

When switch SW2, SW3 and SW4 are flipped to "RUN", the motor begins 10 rotate. When these switches are flipped to "STOP", the motor stops instantaneously. Braking current runs through the motor winding for approximately 0.4 seconds and the power is cut automatically.

These diagrams an refer clock wise(CW) rotation as viewed from the front shaft end ol the motor. To rotate the motor in a counter ciockwise(CCW). exchange U and V phase. Don't Change the direction of rotation for 0.4seconds after operating brake function.

Use power relay with wide contact point. If relay with narrow contact point is used on SW2 and SW3. circuit elements may be damaged by spark. (Contact point capacity AC 250V. over 7A) Use CR circuit for absorbing surge voltage to keep out spark. » Rk5~200j? 1/4W over B Ci:0.l~0.2aF over 500WV

I Three-phase brake pack has noise filter inside. However, it can not remove noise perfectly. Please connect with Ro and Co. (See the Schematic Diagram)

Ro, Co spec is as follow.

* Ro: 21S. 5W and more Co: o.47uf. 500VAC and more

Even when three-phase brake pack is used in short operating cycles such as inching operation, the motor can be stopped instantaneously. However, consider maximum load condition because for three-phase motor, temperature may be changed according to the given load. When motor repeats starting and stopping in short cycle of more than one instantaneous stop per 5 seconds, the rise of motor temperature will increase rapidly. The temperature of the motor case should be maintained 90'C and less regardless of operating cycles.
