TECHNICAL NOTE

(f) POT & C phase pulse method

The movement starts at the approach speed, and moves to the stroke limit in a positive direction.

The movement is reversed when POT signal is detected at the creep speed.

POT signal is passed in reversed direction and C pulse is detected, the final positioning is

performed. The machine coordinate system is established with the position to be the HOME.

The amount of the movement from C phase pulse is set in the final travel distance of homing.

Positioning speed is set in the rapid feed speed.

When the OT signal is detected while moving at the positioning speed, it becomes OT alarm.

Note: The stop method when the OT signal is detected follows the user constant setting of the servo

amplifier.

TRAVSPD Speed of rapid

feed

Traverse speed in count/second.

0-Max speed (ML3**12)

APRSPD Approach

speed

Approach speed in count/second.

0-Max speed (ML3**12)

CRPSPD Creep rate Creep speed in count/second.

0-Max speed (ML3**12)

OFFSET Offset value Final moving distance. And the position will be this

value. If the value is positive, the final moving is in

the same direction of homing. If it is negative the

final moving will be in the opposite of homing
