3.9 Servo motor with electromagnetic brake

CAUTION

Configure the electromagnetic brake o peration circuit so that it is activate d not only

by the servo amplifier signals but also by an external emergency stop signal.

EMGRA

24VDC

Contacts must be open when

servo-on signal is off or when an

alarm (trouble) is present and when

an electromagnetic brake signal.

Electromagnetic brake

Servo motor

Circuit must be

opened during

emergency stop signal.

The electromagnetic brake is provide d for holding purpose and m ust not be used

for ordinary braking.

POINT

Refer to the Servo Motor Instruction Manual for specifications such as the

power supply capacity and operation delay time of the electromagnetic

brake.

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) Set " 1 " in parameter No.1 to make the electromagnetic bra ke interlock signal (MBR) valid.

Note that this will make the zero sp eed signal (ZSP) unavailable.

2) Do not share the 24VDC interface power supply between the interface and electromag netic

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 signal is on, th e base circuit is shu t off. When using the servo motor with a

vertical shaft, use the electromagne tic brake interlock signal (MBR).

5) Switch off the servo-on signal after the servo motor has stopped.

1) Set " 1 " in parameter No.1 to make the electro magnetic brake interlock signal ( MBR) valid.

2) Using parameter No.33 (electromagnet ic brake sequence output), set a time delay from

electromagnetic brake operation to base circuit shut-off as in the timing chart shown in (3) in this

section.
