4. OPERATION AND DISPLAY

4.2 Start up

Do not operate the switches with wet hands. You may get an electric shock.

Do not operate the controller with the front cover removed. High-voltage terminals WARNING and charging area exposed and you may get an electric shock.

During power-on or operation, do not open the front cover. You may get an electric shock.

Before starting operation, check the parameters. Some machines may perform unexpected operation.

CAUTION During power-on or soon after power-off, do not touch or close a parts (cable etc.) to the servo amplifier heat sink, regenerative brake resistor, servo motor, etc. Their temperatures may be high and you may get burnt or a parts may damaged.

Connect the servo motor with a machine after confirming that the servo motor operates properly alone.

(1)Power on

When the main and control circuit power supplies are switched on, "d1" (for the first axis) appears on the servo amplifier display.

In the absolute position detection system, first power-on results in the absolute position lost (25) alarm and the servo system cannot be switched on. This is not a failure and takes place due to the uncharged capacitor in the encoder.

The alarm can be deactivated by keeping power on for a few minutes in the alarm status and then switching power off once and on again.

Also in the absolute position detection system, if power is switched on at the servo motor speed of 500r/min or higher, position mismatch may occur due to external force or the like. Power must therefore be switched on when the servo motor is at a stop.

(2)Parameter setting

Set the parameters according to the structure and specifications of the machine. Refer to Chapter 5 for the parameter definitions.

Parameter No.	Name	Setting	Description
7	Rotation direction setting	0	Increase in positioning address rotates the
			motor in the CCW direction.
8	Auto tuning	1	Used.
9	Servo response	5	Slow response (initial value) is selected.

After setting the above parameters, switch power off once. Then switch power on again to make the set parameter values valid.
