5 Trial Operation
This chapter explains how to check the connections of the power supply, servomotor main circuit, and
encoder cables. Servomotor malfunction is often caused by incorrect wiring.
After having confirmed that the cables are correctly connected, use CX-Drive
*
to perform a trial operation
of the servomotor without connecting to a load, using the following procedure.
* Software used to perform trial operation, change parameters, and monitor the SERVO-
PACK operation and status.
• Conduct trial operation on the servomotor alone with the motor shaft disconnected from machine to
avoid any unexpected accidents.
Failure to observe this caution may result in injury.
• During the JOG operation and the home position search operation using CX-Drive, the forward run
prohibited (P-OT), reverse run prohibited (N-OT), and emergency stop (E-STP) signals will be
ignored. Alternative measures must be taken in case of overtravel and emergency stop.
Procedure
Descriptions
1. Install the SERVOPACK and servomotor.
• Install the servomotor and SERVOPACK according to
the installation instructions in the relevant manual
(see
2.2
Installation Method
). Fix the servomotor
flange on the machine. If the servomotor is not fixed,
it may flip over at operation start or stop.
Install the
SERVOPACK in the control panel.
2. Wire the cables.
• Wire the power supply, servomotor main circuit, and
encoder cables according to the instructions in
3
Wir-
ing
.
• Disconnect the I/O signal connector (CN1).
• When using a servomotor with a brake, wire the
brake power supply cable and signal lines such as
the relay.
