4.3.4 Setting for Holding Brakes
The holding brake is used when the servo drive controls a vertical axis.
A servomotor with the brake option helps prevent movable parts from shifting due to gravity when power is removed from
the servo drive.
(Refer to
4.1.4 Trial Operation for Servomotor with Brakes
.
)
1. The servomotor with the built in brake, is a de-energization brake. It is used to hold the servomotor and cannot be used
as a braking purposes. Use the holding brake only to hold a stopped servomotor.
2. When operating using only a speed loop, turn OFF the servo and set the input reference to 0V when the brake is
applied.
3. When forming a position loop, do not use a mechanical brake while the servomotor is stopped because the servomotor
enters servolock status.
