5 Operation
5.2.4 Holding Brakes
∗1. The operation delay time of the brake is shown in the following table. The operation delay time is an example when
the power supply is turned ON and OFF on the DC side. Be sure to evaluate the above times on the actual equipment
before using the application.
Main Circuit Power
Three-phase
200 VAC
Three-phase
400 VAC
∗2. After the/S-ON signal has turned ON and 50 ms has passed since the brake was released, output the reference from
the host controller to the SERVOPACK.
∗3. Use Pn506, Pn507, and Pn508 to set the timing of when the brake will be activated and when the servomotor power
will be turned OFF.
(1) Wiring Example
Use the brake signal (/BK) and the brake power supply to form a brake ON/OFF circuit. The following dia-
gram shows a standard wiring example.
The timing can be easily set using the brake signal (/BK).
