Note
If executing helical interpolation, 3 axes will operate at the same time. Need user to pay attention.
(1) Auxiliary operations may be used are as follows.
▪ Speed override, Dec. stop, Emergent stop, Skip operation.
(2) The commands may not be used in circular interpolating operation are as follows.
▪ Position/Speed switching control, Position override, Continuous operation
(3) The parameter items operating by standards of each axis are as follows.
▪ Amount of backlash revision in extended parameter items, Software high limit, Software low limit
(3) Example of operation data setting

Description
Control
method
Absolute, Circular
interpolation
-
*1
-
*1
Circular interpolation must be set when executing
helical interpolation
Operation
method
Singular, End - - Set operation method for helical interpolation
Goal
position[pls]
10000 0 10000
Set the goal position on main, sub, helical axis for
executing positioning.
Operation
speed[pls/s]
1000 - -
Helical interpolation designates composition speed
of circular interpolation part
Acc. no. No.1 - - Set acc. time no. used in acceleration (no.1 ~ no.4)
Dec. no No.2 - - Set dec. time no. used in deceleration (no.1 ~ no.4)
M code 0 - -
Set it when user needs to synchronize another
auxiliary operation with helical interpolation.
Dwell time 500 - -
Set dwell time(ms) for outputting positioning
complete signal
Sub axis
setting
Axis2 - -
Set an axis to be used as sub axis from settable
axis on main axis operation data
Auxiliary point
of Circular
interpolation
5000 5000 - Set auxiliary data of circular interpolation action
Circular
interpolation
mode
Middle point - -
Set circular interpolation mode to be used in circular
action of helical interpolation
No. of turn of
circular
interpolation
0 - -
Set the no. of turn of circular arc when user need to
execute helical interpolation of bigger degree than
360°
Helical
interpolation
Axis3 - -
Set an axis to be used as helical interpolation axis
from settable axis on main axis operation data
-
*1
: This item does not need to be set. Whatever it is set as, it dose not affect circular interpolation.
Note
Helical interpolation control is executed on the item basis set on operation data of main axis.
When executing circular interpolation of helical interpolation, only “Goal position”, “Auxiliary point of circular interpolation”
items of sub axis setting and “Goal position” item of helical axis setting affect helical interpolation. In other words,
Whatever the setting value is, it does not affect operation and cause any errors.
