6. DISPLAY AND OPERATION

6.8.3 Positioning operation

POINT

The servo configuration software is required to perform positioning operation.

Positioning operation can be performed once when there is no command from the external command device.

(1)Operation

Connect EMG-SG to start positioning operation and connect VDD-COM to use the internal power supply.

Pressing the "Forward" or "Reverse" button on the servo configuration software starts the servo motor, which will then stop after moving the preset travel distance. You can change the operation conditions on the servo configuration software. The initial conditions and setting ranges for operation are listed below:

Item	Initial setting	Setting range
Travel distance [pulse]	10000	0 to 9999999
Speed [r/min]	200	0 to instantaneous permissible speed
Acceleration/deceleration time constant [ms]	1000	0 to 50000

How to use the keys is explained below:

	Key	Description
	"Forward"	Press to start positioning operation CCW.
	"Reverse"	Press to start positioning operation CW.
		Press during operation to make a temporary stop. Pressing
	"Pause"	the "Pause" button again erases the remaining distance.
	"Pause"	To resume operation, press the button that was pressed to
		To resume operation, press the button that was pressed to
		start the operation.

If the communication cable is disconnected during positioning operation, the servo motor will come to a sudden stop.

(2)Status display

You can monitor the status display even during positioning operation.
