10-2-5 Monitoring For Instruction Errors - Omron NX701-1 User Manual

10-2-5 Monitoring for Instruction Errors

In this sample, further processing is not performed if there is an error when the MC_Power (Power
Servo) instruction is executed. Whether further processing is possible is indicated by the UpgOn vari-
able.
Samples are provided for both ladder diagram and ST programming.
Main Variables Used in the Programming Samples
Variable name
MC_Axis000
Pwr_Status

Ladder Diagram
Check if the Servo Drive is ready when StartPg is TRUE.
StartPg
If the Servo Drive is ready, turn ON the Servo for axis 0.
Lock0
A check is made to see if any errors occurred when MC_Power was executed before execution of further processing.

10 Sample Programming
Default
--- This is the Axis Variable for axis 0.
FALSE This variable is assigned to the Status output
variable from the PWR instance of the
MC_Power instruction. It is TRUE when the
Servo is ON.
FALSE This variable is assigned to the Busy output
variable from the PWR instance of the
MC_Power instruction. It is TRUE when the
Servo is ON.
FALSE When StartPg is TRUE, the Servo is turned ON
if EtherCAT process data communications are
active and normal.
FALSE TRUE if further program execution is performed.
