6-4 Trial Operation

6-4 Trial Operation

When you have finished installation, wiring, Servomotor/Servo Drive jog operation, and user
parameter setting, perform trial operation.
The main purpose of trial operation is to confirm that the servo system operates electrically
correctly. Make sure that the host position controller and all peripheral devices are connected, and
turn ON the power. Then perform trial operation at low speed to confirm the operation. Next, perform
actual run patterns to confirm that the system works properly.

Preparation for Trial Operation

Turning OFF the Power
Some parameters are enabled by turning OFF the power and turning it ON again. First turn OFF the
main circuit power.
Preparing for Turning OFF the Servomotor
In order that the Servomotor can be immediately turned OFF if an abnormality occurs in the
machine, set up the system so that the power and the RUN Command Input can be turned OFF.
Trial Operation
1. Operating without a Load
Turn ON the power to the main circuit and peripheral devices, and then turn ON the RUN
Command Input.
Check that the Servomotor is in Servo ON status.
Send the command to start the Servomotor from the host position controller, and check that the
Servomotor operates properly according to the command. (Check that the Servomotor is rotating
in the correct direction and the rotation speed and amount of rotation are as specified by the
command.)
2. Mechanical System Connection
Turn OFF the power.
Firmly connect the Servomotor shaft to the load (i.e., the mechanical system). Tighten screws and
make sure they are not loose.
Turn ON the power.
3. Low-speed Operation with Actual Load Connected
Send a low speed command from the host position controller to start the Servomotor. (The
definition of "low speed" depends on the mechanical system, but a rough estimate is 1/10 to 1/5
of normal operating speed.)
Check the following items.
a) Are the emergency stop and over load switch operating correctly?
b) Is the operating direction of the machine correct?

If an error occurs during the trial operation, refer to Chapter 8
Troubleshooting to eliminate the cause. Then ensure safety and resume
operation.
If the machine vibrates when starting or stopping, refer to Chapter 7
Adjustment Functions and perform the gain adjustment first.
