Linear Interpolation
Section 9-7

Linear Interpolation Operation
After the data related to linear interpolation has been set, linear interpolation
operation is started by means of the following two operations.
Executing LINEAR INTERPOLATION SETTING
Turn ON the LINEAR INTERPOLATION SETTING Bit in the Axis 1 (or Axis 5)
Operating Output Memory Area.
When this bit is turned ON, the settings for linear interpolation operation that
have been set in the Axis Operating Output Memory Area for axis 1 (or axis 5)
are obtained, along with the position command values and position speed val-
ues for individual interpolation axes, and preparations will be executed for lin-
ear interpolation operation. Execute LINEAR INTERPOLATION SETTING
when the Linear Interpolation Setting Completed Flag in the Axis Operating
Input Memory Area for axis 1 (or axis 5), and the Busy Flag and Error Flag for
the axes designated by the interpolation axis designation, are reset. If the Lin-
ear Interpolation Setting Completed Flag for axis 1 (or axis 5) is set, or if an
axis designated by the interpolation axis designation is busy (i.e., Busy Flag
ON), or if an error has occurred (i.e., Error Flag ON), the LINEAR INTERPO-
LATION SETTING command will be ignored and will not be executed.
When LINEAR INTERPOLATION SETTING has been successfully com-
pleted, the Linear Interpolation Setting Completed Flag for axis 1 (or axis 5)
will be set.
Note
(1) LINEAR INTERPOLATION SETTING is automatically written from the
PCU to the Servo Parameters. When executing LINEAR INTERPOLA-
TION SETTING, do not execute any of the Servo Parameter transfer op-
erations (WRITE, READ, or SAVE).
(2) When LINEAR INTERPOLATION SETTING is executed, the
Sec-
ond-step Linear Acceleration Constant
for W-series Servo Drives
(Pn80B),
Linear Acceleration Constant
for G-series Servo Drives (Pn107)
or
Linear Acceleration Constant
for G5-series Servo Drives (Pn811) and
Second-step Linear Deceleration Constant
for W-series (Pn80E),
Linear
Deceleration Constant
for G-series Servo Drives (Pn10A) or
Linear De-
celeration Constant
for G5-series Servo Drives (Pn814) parameters in
the Servo Parameters are changed. Be careful of changes to acceleration
and deceleration speed settings if interpolation axes are operated inde-
pendently (by direct operation, JOG, etc.) after LINEAR INTERPOLA-
TION SETTING has been executed (regardless of whether LINEAR
INTERPOLATION START has been executed). Change the
Second-step
Linear Acceleration Constant
for W-series Servo Drives (Pn80B),
Linear
Acceleration Constant
for G-series Servo Drives (Pn107) or
Linear Ac-
celeration Constant
for G5-series Servo Drives (Pn811) and
Second-step
Linear Deceleration Constant
for W-series (Pn80E),
Linear Deceleration
Constant
for G-series Servo Drives (Pn10A) or
Linear Deceleration Con-
stant
for G5-series Servo Drives (Pn814) as required, by using a WRITE
SERVO PARAMETERS command.
Executing LINEAR INTERPOLATION START
Turn ON the LINEAR INTERPOLATION START Bit in the Axis 1 (or Axis 5)
Operating Output Memory Area. Linear interpolation operation will start,
based on the settings from when the LINEAR INTERPOLATION SETTING Bit
was turned ON just before. If the LINEAR INTERPOLATION SETTING Bit is
OFF, LINEAR INTERPOLATION START will be disabled.
