CAUTION
Configure an electromagnetic brake circuit which is interlocked with an external
emergency stop switch.

Contacts must be opened when CALM (AND malfunction)
or MBR (Electromagnetic brake interlock) turns off.
24 V DC
Contacts must be opened with the
emergency stop switch.
The electromagnetic brake is provided for holding purpose and must not be used
for ordinary braking.
Before operating the servo motor, be sure to confirm that the electromagnetic
brake operates properly.
Do not use the 24 V DC interface power supply for the electromagnetic brake.
Always use the power supply designed exclusively for the electromagnetic brake.
Otherwise, it may cause a malfunction.
When using EM2 (Forced stop 2), use MBR (Electromagnetic brake interlock) for
operating the electromagnetic brake. Operating the electromagnetic brake without
using MBR during deceleration to a stop will saturate servo motor torques at the
maximum value due to brake torques of the electromagnetic brake and can result
in delay of the deceleration to a stop from a set value.
POINT
Refer to "Servo Motor Instruction Manual (Vol. 3)" for specifications such as the
power supply capacity and operation delay time of the electromagnetic brake.
Refer to "Servo Motor Instruction Manual (Vol. 3)" or section 11.19 for the
selection of a surge absorber for the electromagnetic brake.
Note the following when the servo motor with an electromagnetic brake is used.
1) The brake will operate when the power (24 V DC) turns off.
2) Turn off the servo-on command after the servo motor stopped.
