Controlling Vertical Axes

This section describes the connection methods and parameter settings that are required to use
the SERVOPACK to control a vertical axis.
6.1.1

SERVOPACK Holding Brake

When a SERVOPACK is used to control a vertical axis or an axis to which an external force is
being applied, a Servomotor with a brake must be used to prevent the work load from dropping
or moving due to gravity or the external force when the system power supply is turned OFF.
The holding brake of the Servomotor is controlled through the brake output (/BK) signal from
the SERVOPACK. MP3000 brake control is not performed.
The brake that is built into the Servomotor uses non-excitation operation. It is for use as a holding
brake only. It cannot be used to control or stop axis movement. Use the holding brake only to
hold the axis in a stopped state after the motor has stopped. The torque of the brake is 100% or
higher of the rated torque of the motor.
