3.7 Servo motor with electromagnetic brake
Connection diagram
Please observe closely the following instructions for the use of a servo motor with
electromagnetic brake.
 Provide a separate power source of 24VDC for the electromagnetic brake.
 The brake will operate when the power switches off.
 Switch off the SON command after the servo motor has stopped.
b
CAUTION:
Configure the electromagnetic brake circuit so that it is activated not only by the
interface unit signals but also by a emergency stop.
b
CAUTION:
The electromagnetic brake is only intended for holding a static load, e.g. from vertical
lifting axes. The braking effect and frequent switching of the EMERGENCY OFF
function will result in the destruction of the brake after only a few cycles.
