4.2. Additional Setup Procedures in Trial Operation
For two equipment configurations, which are delineated in the subsequent
sections, precautionary setup procedures must be followed before starting trial
operation.
4.2.1. Servomotors with Brakes
Use a servomotor with a brake for vertical shaft applications or for the
application of external force to the shaft to prevent rotation due to
gravity or external force during a power loss.
The servo amplifier uses the brake interlock output (/BK) signal to
control the holding brake operation when using servomotors with
brakes.

Note: To prevent faulty operation when using gravity or external force, first make sure that both the
servomotor and the holding brake work properly. When assured that each operates properly, connect the
servomotor to the rest of the equipment to start the trial operation.
The following figure shows wiring for a servomotor with brakes. See
5.4.4 Using the Holding Brake for details on wiring.
