[Pr.55] Operation setting for incompletion of home position return
Set whether the positioning control is executed or not (When the home position return request flag is ON.).
0: Positioning control is not executed.
1: Positioning control is executed.
• When the home position return request flag is ON, selecting "0: Positioning control is not executed" will result in the error
"Start at home position return incomplete" (error code: 19A6H), and positioning control will not be performed. At this time,
operation with the manual control (JOG operation, inching operation, manual pulse generator operation) is available. The
positioning control can be executed even if the home position return request flag is ON when selecting "1: Positioning
control is executed".
• The following shows whether the positioning control is possible to start/restart or not when selecting "0: Positioning control
is not executed".
Start possible Machine home position return, JOG operation, inching operation, manual pulse generator operation, and current value
changing using current value changing start No. (9003)
Start/restart impossible When the following cases at block start, condition start, wait start, repeated start, multiple axes simultaneous start and pre-
control reading start
1-axis linear control, 2/3/4-axis linear interpolation control, 1/2/3/4-axis fixed-feed control, 2-axis circular interpolation control
(with sub point designation/center point designation), 3-axis helical interpolation control (with sub point designation/center point
designation), 1/2/3/4-axis speed control, speed-position switching control (INC mode/ ABS mode), position-speed switching
control, and current value changing using current value changing (No.1 to 600)
• When the home position return request flag is ON, starting the fast home position return will result in the error "Home
position return request ON" (error code: 1945H) despite the setting value of "Operation setting for incompletion of home
position return", and the fast home position return will not be executed.
CAUTION
• Do not execute the positioning control in home position return request signal ON for the axis which uses in the positioning control. Failure to observe this
could lead to an accident such as a collision.
[Pr.56] Speed designation during home position shift
Set the operation speed for when a value other than "0" is set for "[Pr.53] Home position shift amount". Select the setting from
"[Pr.46] Home position return speed" or "[Pr.47] Creep speed".
0: Designate "[Pr.46] Home position return speed" as the setting value.
1: Designate "[Pr.47] Creep speed" as the setting value.
[Pr.57] Dwell time during home position return retry
When home position return retry is validated (when "1" is set for [Pr.48]), set the stop time after decelerating in 2) and 4) in the
following drawing.
5)
Temporarily stop for
the time set in [Pr.57].
4)
1)
6)
Start position
3)
Temporarily stop for
