4.OPERATION

(i)Position latch (LPOS)

POINT

When Current position latch input (LPS) is used to store the current position, the value differs depending on the servo motor speed provided when LPS has turned ON.

The current position where Current position latch input (LPS) is turned ON is stored. The stored position data can be read by the communication function. (Refer to Section 15.12.12)

The current position latch function set in a program is canceled at the end of that program. It is also canceled when the operation mode is changed, a forced stop is made, an alarm occurs, or the servo switches off. It is not canceled when a temporary stop is merely made.
