Electromagnetic brake

The electromagnetic brake is provided for holding the motor shaft. Do not use it for ordinary braking.

POINT

For the power supply capacity, operation delay time and other specifications of the electromagnetic brake, refer to the Servo Motor Instruction Manual.

Note the following when the servo motor equipped with electromagnetic brake is used for applications requiring a brake to hold the motor shaft (vertical lift applications):

1)In the device setting of the Servo Configuration software, make the electromagnetic brake interlock (MBR) available.

2)Do not share the 24VDC interface power supply between the interface and electromagnetic brake. Always use the power supply designed exclusively for the electromagnetic brake.

3)The brake will operate when the power (24VDC) switches off.

4)While the reset (RES) is on, the base circuit is shut off. When using the servo motor with a vertical shaft, use the electromagnetic brake interlock (MBR).

5)Turn off the servo-on (SON) after the servo motor has stopped.

(2)Setting

1)In the device setting of the Servo Configuration Software, make the electromagnetic brake interlock (MBR) available.

2)Using parameter No. 33 (electromagnetic brake sequence output), set a time delay (Tb) at servo-off from electromagnetic brake operation to base circuit shut-off as in the timing chart shown in (3) in this section.
