TECHNICAL NOTE

(b) ZERO signal method

The movement starts at the approach speed in the direction specified by the parameter. Speed

is decelerated to the creep speed at the rising edge of the ZERO signal and finishes positioning.

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

The amount of the movement from the ZERO signal is set in the final travel distance of homing.

When the OT signal is detected while in homing process, it becomes OT alarm.

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
