Wiring Integral Holding Brakes
The integral holding brakes of AMP servo motors require between 200 and 400 mA at 24
VDC to operate properly. To wire and operate a holding brake from the Y1/Brake output of an
Applied Motion servo drive requires the following items:
•
A 24 VDC power supply with minimum output of 450 mA
•
A 24 VDC relay*
•
A clamp diode such as 1N4935*
•
An AMP servo motor with integral holding brake, designated by a “5” in the 7th position of
the motor part number. Example: M0400-151-4-000
•
A “BK” type motor power cable or separate brake cable. Example: BLUMTR-BK-FA-10
* Relays with an integral clamp diode, like IDEC part number RU2S-D-D24, greatly simplify
the wiring effort by including the relay and a clamp diode in one unit.
Following the diagram below, connect the power supply, relay, and diode to the brake leads of
the servo motor, as well as the Y1/Brake output connections of the servo drive.
