CAUTION
Note the following when the servo motor equipped with electromagnetic brake is used.
1) Set "
this will make the zero speed signal (ZSP) unavailable.
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) Switch off the servo-on signal after the servo motor has stopped.

3.9.2 Setting

1) Set "
2) Using parameter No.33 (electromagnetic brake sequence output), set a delay time (Tb) at servo-off from
electromagnetic brake operation to base circuit shut-off as in the timing chart shown in section 3.9.3.
Configure the electromagnetic brake operation circuit so that it is activated not only
by the servo amplifier signals but also by an external emergency stop (EMG).
Contacts must be open when
servo-off, when an trouble (ALM)
and when an electromagnetic brake
interlock (MBR).
The electromagnetic brake is provided for holding purpose and must not be used
for ordinary braking.
Before performing the operation, be sure to confirm that the electromagnetic brake
operates properly.
POINT
Refer to chapter 14 for specifications such as the power supply capacity and
operation delay time of the electromagnetic brake.
Refer to section 3.8 for wiring diagrams.
