(2) Restrictions
(a) The restrictions of helical interpolation are same as various kinds of circular interpolation depending on the
mode of circular interpolation.
(b) If you set
「
Helical Interpolation
」
as
“Don‟t use”, it will be same as the action of circular interpolation.
(c) If you set the target position of helical interpolation axis as the same starting position, it will be same as the
action of circular interpolation.
Remark
If you execute helical interpolation, 3 axes will operate at the same time. Pay attention.
(1) Available auxiliary operations are as follows.
▪ Speed override, Dec. stop, Emergent stop, Skip operation.
(2) The commands unavailable during helical interpolation operation are as follows.
▪ Position/Speed switching control, Position override, Continuous operation
(3) The parameter items operated by each axis setting are as follows.
▪ Software high limit, Software low limit among extended parameter.
(3) Example of operation data setting
