5. OPERATIONAL FUNCTIONS
5.4.2 Settings
The following items are defined for performing linear interpolation. Refer to Section 5.3 concerning details for
the point table.
(1) Setting 1: Items set for all axes to be interpolated.
Items Content Remarks
Point table Position data Define setting within maximum moveable limits.
(Maximum moveable limit
999999999)
Other axes start specification Define the setting when using the other axes start.
Pass position interrupt specification Define the setting when using the pass position
interrupt.
Axis data Start point number
End point number
Define the settings such that the number of points
between start and finish is the same for all axes in the
group configuration.
Axis data (command bit) Linear interpolation mode signal (LIP) Turn on this bin.
Control parameter Linear interpolation group (parameter No.0260) Define the valid group number.
The maximum number of axes that can be defined for
a group is 4.
For tandem drive axes, only the master axis must be
set.
Speed limit value (parameter No.0222, 0223) Defines the speed limit for each axis. Used when
selecting "speed clamp" or "alarm stop" as control
options for excessive speed processing.
(2) Setting 2: Items defined for the primary axis (axis where start operation signal (ST) is input)
Items Content Remarks
Point table for primary axis Feed speed
Acceleration time constant (ms)
Deceleration time constant (ms)
Dwell (ms)
Auxiliary command
S-curve ratio [%]
Control parameters for the
primary axis
Speed units (parameter No.0200)
Linear interpolation options (parameter No.0261)
Linear interpolation speed limit value
(parameter No.0262, 0263)
Start up speed (parameter No.0224, 0225)
Speed units multiplication factor (parameter
No.020E, 020F)
The r/min of the units for speed can not be set.
