This is the operation to move the motor to the origin.
About the Zero return operation pattern,
The Zero return operation has the following unique features.
・The Zero return end direction can be specified.
Origin limit sensor is not necessarily high-precision sensor. Therefore, there may be a position error between when the limit is detected from the positive direction and when the limit is detected from the negative direction. To solve this problem, always detect the origin limit from only one direction.
・NORG (near origin) is not required.
When returning to origin using acceleration/deceleration
movement, a deceleration stop limit sensor
is required as a NORG near the origin limit in order to reliably stop
at the origin limit.
A single origin limit sensor plays the role
of a NORG.
