Over Limit Input - Panasonic GM1 Series Reference Manual

10.6 Over Limit Input

Operations depend on the status of over limit input (+) and over limit input (-) as follows.
■
Operation at over limit input (Home search is valid)
Condition
When home return
operation is executed
During home return
operation
■
Operation at over limit input (Home search is invalid)
Condition
When home return
operation is executed
During home return
operation
■
Input valid logic of over limit input
● When the over limit switches (+) (-) are not connected to the pulse output unit, change the
over limit input valid logic of the Pulse_4Axes parameter to "NO contact". The default is "NC
contact", and an over limit error occurs.
■
Precautions on over limit switch
● An over limit input valid for JOG operation, home return and pulser operation is the one
logically found in the direction of the movement. Even if an over limit switch (-) is input for a
movement in (+) direction or an over limit switch (+) is input for a movement in (-) direction,
the operation will not stop.
● Make sure that an over limit switch (+) is set in the direction of the elapsed value increment
and an over limit switch (-) in the direction of the elapsed value decrement.
● When a switch is not set in the correct direction, the followings might be a cause. Check your
settings and correct them.
1) An over limit switch, (+) or (-), is not set in a correct direction.
2) CW / CCW output method is set reverse for the connection of the pulse output unit and
the motor driver.
3) A sign input logic is set reverse for the connection of the pulse output unit and the motor
driver.
