10 Sample Programming
10-6
NJ-series CPU Unit Motion Control User’s Manual (W507)
You can place the MC_Power (Power Servo) instruction between the MC (Master Control Start) and
MCR (Master Control End) instructions in ladder diagrams to interlock axis operation. When
Mc_On
is
FALSE in this sample, the MC_Power (Power Servo) instruction between the MC and MCR instructions
is disabled to turn OFF the Servo. The
CommandAborted
output variable from the current motion con-
trol instruction changes to TRUE at the same time, and axis motion stops.
You cannot use the MC instruction in ST. Therefore, a sample is provided only for a ladder diagram.
10-2-2 Interlocking Axis Operation with Master Control Instructions
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.MFaultLvl.Active
BOOL
FALSE
TRUE when there is a minor fault level error for
axis 0.
Mc_On
BOOL
FALSE
This variable enables and disables the MC
instruction. Control programming is not given in
this sample. In actual programming, program
controls for the required device operation.
StartPg
BOOL
FALSE
When
StartPg
is TRUE, the Servo is turned ON
if EtherCAT process data communications are
active and normal.
