Origin Return - Omron CP1E CPU UNIT SOFTWARE User Manual

12 Pulse Outputs

12-4-6 Origin Return

It is the function to move the origin to the defined position by origin searches or changing PVs.
An origin return operation moves the motor to the origin position from any other position. The origin
return operation is controlled by ORG.
The origin return operation returns the motor to the origin by starting at the specified speed, accelerat-
ing to the target speed, moving at the target speed, and then decelerating to a stop at the origin posi-
tion.

Note An instruction execution error will occur if the origin is not defined (relative coordinate system)
when the ORG instruction is executed to perform an origin return operation.

Origin return target speed
Start
Sets the motor's starting speed when the
origin return is executed. Specify the speed
in the number of pulses per second (pps).
Sets the motor's target speed when the
origin return is executed. Specify the speed
in the number of pulses per second (pps).
Sets the motor's acceleration rate when the
origin return function is accelerating. Specify
the amount to increase the speed (Hz) per
4-ms interval.
Sets the motor's deceleration rate when the
origin return function is decelerating. Specify
the amount to decrease the speed (Hz) per
4-ms interval.
