1. Data of this area is not subject to errors.
2. When the near home input will not go ON but the Over limit input in the opposite goes ON after
the table reversed the direction by the Over limit switch during the home search, a limit error occurs.
Note: Pulse/Sign output mode can be started up.
When the CW/CCW output mode is set, the limit error will occur.
If the error occurs, solve it using the methods as described below.
·Using the home return function
(1) Turn ON the Error clear (Y_F) of the Over limit input (+), and then turn it OFF.
(2) Turn ON the Home return start (Y_F) (towards the elapsed value minus (-) direction), while the
Over limit input (+) is ON.
·Using the JOG operation function
(1) Turn ON the Error clear (Y_F) of the Over limit input (+), and then turn it OFF.
(2) Turn ON the Reverse JOG (Y_4), while the Over limit input (+) is ON.
