9.1 Controlling Vertical Axes
This section explains connection methods and parameter settings required to use the
SERVOPACK to control a vertical axis.
9.1.1 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 MP2200/MP2300. Use the holding brake function of the
SERVOPACK.
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.
