Introduction
This manual explains descriptions about the electromagnetic brake
for the "2-phase stepping motor PKP Series with electromagnetic
brake." Refer to the operating manual of the PKP Series for the
motor itself.

Safety precautions
The precautions described below are intended to prevent danger or
injury to the user and other personnel through safe, correct use of
the product. Use the product only after carefully reading and fully
understanding these instructions.
Handling the product without observing the instructions that
accompany a "Warning" symbol may result in serious injury or
death.
yDo not use the electromagnetic brake to reduce speed or as a safety
brake.
Do not use the electromagnetic brake as a means to decelerate
and stop the motor. The brake hub of the electromagnetic brake
will wear signicantly and the braking force will drop. Since the
power off activated type electromagnetic brake is equipped, it
helps maintain the position of the load when the power is cut off,
but this brake cannot securely hold the load in place. Accordingly,
do not use the electromagnetic brake as a safety brake. To use the
electromagnetic brake to hold the load in place, do so after the
motor has stopped.

OPERATING MANUAL Thank you for purchasing an Oriental Motor product.
This Operating Manual describes product handling procedures and
safety precautions.
•Please read it thoroughly to ensure safe operation.
•Always keep the manual where it is readily available.
2-Phase Stepping Motor
PKP Series Electromagnetic brake
Connection and operation
1. Connect the surge suppressor (supplied) in parallel between
the +24 VDC terminal of the DC power supply and the GND
terminal.
The surge suppressor does not have polarity.
2. Connect the lead wires of the "cable for electromagnetic brake" to
the DC power supply.
Connect the red lead wire to +24 VDC terminal, and the black
lead wire to GND terminal.
3. Apply a voltage to the electromagnetic brake to release it.

Note
•Do not apply the voltage beyond its specications.
Doing so may increase the temperature rise in the
electromagnetic brake, resulting in damage to the
motor. Conversely, insufcient voltage may prevent the
brake from releasing.
•Be sure to connect the surge suppressor to protect the
contact of the switch or to prevent electrical noise.
•The lead wires of the "cable for electromagnetic
brake" have polarities, so connect them in the correct
polarities. If the lead wires are connected with their
polarities reversed, the electromagnetic brake will not
operate properly.
