Holding Brake
Chapter 5
Holding Brake
A holding brake is used to hold the position of the moving part of the machine when the drive is turned
off, so that moving part does not move due to gravity or an external force.
IMPORTANT
ONLY AXIS 3 AND AXIS 4
have holding brakes.
The brake integrated into the motor is a de-energization brake. It is used only to
hold the motor once stationary and cannot be used for braking.
Use the holding brake only to hold a motor that is stationary.
Motors of
axis 3 and axis 4
have a holding brake. A digital output on the drive can be assigned for brake
control. Any of the digital outputs on the drive can be configured as the brake control output.
The assignment is made by selecting from the Basic Setup page in the drive commissioning screens or by
writing directly to parameter Pn511.
Selecting a digital output in the Basic Setup screen will enable the brake control timing parameters.
