14.1 Controlling a Vertical Axis

This section explains connection methods and parameter settings required to use the SERVOPACK to control a
vertical axis.
14.1.1 Overview
When the system power is turned OFF when using a SERVOPACK 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 axis from dropping or
moving due to gravity or the external force.
The holding brake of the Servomotor is controlled through the brake interlock output (BK) signal from the
SERVOPACK. The brake is not controlled from the MP2100/MP2100M. Use the holding brake function of the
SERVOPACK.
IMPORTANT
(a) Using the SGDH-
A circuit is configured to turn the brake ON and OFF using the /BK contact output signal from the
SERVOPACK and a brake power supply. The standard connections are shown in the following diagram.

the power is turned OFF.
The brake built into a servomotor with a brake uses non-excitation operation and 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.
