10 Sample Programming
10-54
NJ-series CPU Unit Motion Control User’s Manual (W507)
This sample uses a cam profile curve to correct a slave axis in a gear motion. The slave axis for gear
motion is
MC_Axis001
, a virtual Servo axis, and the slave axis for cam motion is
MC_Axis002
, also a
virtual Servo axis. These slave axes are combined with
MC_CombineAxes
and the results is output to
MC_Axis003
, a Servo axis. The master axis is
MC_Axis000
, a Servo axis.
The processing flow is as follows:
z
Axis Type Settings
The axes types are set in the axis parameters for each axis as given below.

Main Variables Used in the Programming Samples
Variable name
Data type
Default
Comment
MC_Axis000
_sAXIS_REF
---
This is the Axis Variable for axis 0.
MC_Axis000.Details.Homed
BOOL
FALSE
TRUE when home is defined for axis 0.
MC_Axis000.MFaultLvl.Active
BOOL
FALSE
TRUE when there is a minor fault level error
for axis 0.
MC_Axis001
_sAXIS_REF
---
This is the Axis Variable for axis 1.
MC_Axis001.MFaultLvl.Active
BOOL
FALSE
TRUE when there is a minor fault level error
for axis 1.
MC_Axis002
_sAXIS_REF
---
This is the Axis Variable for axis 2.
MC_Axis002.MFaultLvl.Active
BOOL
FALSE
TRUE when there is a minor fault level error
for axis 2.
MC_Axis003
_sAXIS_REF
---
This is the Axis Variable for axis 3.
MC_Axis003.Details.Homed
BOOL
FALSE
TRUE when home is defined for axis 3.
MC_Axis003.MFaultLvl.Active
BOOL
FALSE
TRUE when there is a minor fault level error
for axis 3.
CamProfile0
ARRAY[0..109] OF
_sMC_CAM_REF
---
This is the cam data variable.
*1
Pwr1_Status
BOOL
FALSE
This variable is assigned to the
Status
output
variable from the PWR1 instance of the
MC_Power instruction. It is TRUE when the
Servo is ON.
Pwr4_Status
BOOL
FALSE
This variable is assigned to the
Status
output
variable from the PWR4 instance of the
MC_Power instruction. It is TRUE when the
Servo is ON.
Vel_InVel
BOOL
FALSE
TRUE when the target velocity for
MC_MoveVelocity
for axis 0 is reached.
