4-2
4-1 Trial Operation for Servomotor without Load
To carry out a successful trial run follow the steps below and ensure that drive wiring is correct and as
specified.
1. Installation of servo motor.
Ensure that the motor is installed securely so that there is no movement and vibration during trial run.
2. Wiring.
Check servo drive 、motor power connections and motor encoder connection.
No control signal wiring is required of this stage thus remove connector (CN1) from the servo drive.
3. Servo drive power.
Apply power to servo drive. If the display showed any Alarm message as below, please refer to chapter 8
to identify the cause.
The above is caused by Input terminals CCWL (Counter clockwise Limit) and CWL (Clockwise Limit)
being activated at the same time. See (the default setting of high or low input logic state according to the
description in section 5-6-1 ). Because of the alarm, the servo can not operate normally.
Set the parameter Cn002.1=1 to disable the drive limit function temporarily during trial run period.
In order to prevent potential damage,prior to trial run ensure that the driven
mechanism, couplings and belts etc are disconnected from the motor.
