10 Sample Programming
10-8
NJ-series CPU Unit Motion Control User’s Manual (W507)
You can monitor error status by monitoring the status of Axis Minor Fault Occurrence in the Axis Vari-
able. If a minor fault level error occurs in this sample, the
Enable
input variable for the MC_Power
instruction changes to FALSE to turn OFF the Servo. If the external button is ON and the command cur-
rent velocity is zero, the error is reset with the MC_Reset (Reset Axis Error) instruction. Samples are
provided for both ladder diagram and ST programming.

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_Axis000.Status.ErrorStop
BOOL
FALSE
TRUE while there is a minor fault level error for
axis 0 and the axis is decelerating to a stop or
stopped.
MC_Axis000.Details.Idle
BOOL
FALSE
TRUE when the command current velocity for
axis 0 is zero, except when waiting for in-posi-
tion state.
StartPg
BOOL
FALSE
When
StartPg
is TRUE, the Servo is turned ON
if EtherCAT process data communications are
active and normal.
ResetON
BOOL
FALSE
This variable gives the status of the external
button that is used to reset errors.

If a minor fault level error occurs for axis 0, the error handler for the device (FaultHandler) is executed.
Program the FaultHandler according to the device.
The Servo for axis 0 is turned ON if process data communications are active and normal.
When
StartPg
is TRUE, the status of process data communications is checked to see if communications
are active and normal.
