Motion Error Codes, faults, and attributes
This chapter provides an overview of the error codes, faults and attributes for
motion instructions.
This table lists the error codes for Logix Designer software motion instructions.
Motion Instruction Error Codes Descriptions
Error Corrective Action or Cause Notes
1 Reserved Error Code 1 Reserved for future use.
2 Reserved Error Code 2 Reserved for future use.
3 Look for another instance of this type of instruction. See if its EN bit is on but its
DN and ER bits are off (enabled but not done or erred). Wait until its DN or ER bit
turns on.
Execution Collision
You cannot execute an instruction by using the same control word as another
instruction if the other instruction is not done or has an error. Regardless, it is
recommended that each instruction has a unique control word.
4 Open the servo loop before you execute this instruction. Servo On State Error
5 Close the servo loop before you execute this instruction. Servo Off State Error
For a motion coordinated instruction, refer to the online help for the instruction for
extended error code definitions. They identify which axis caused the error.
Example: If the extended error code is zero, check the axis for index zero of the
coordinate system.
6 Disable the axis drive. Drive On State Error
7 Execute a Motion Axis Shutdown Reset (MASR) instruction or direct command to
reset the axis.
Shutdown State Error
For a motion coordinated instruction, refer to the online help for the instruction for
extended error code definitions. They identify which axis caused the error.
Example: If the extended error code is zero, check the axis for index zero of the
coordinate system.
8 The configured axis type is not correct. Wrong Axis Type
For a motion coordinated instruction, refer to the online help for the instruction for
extended error code definitions. They identify which axis caused the error.
Example: If the extended error code is zero, check the axis for index zero of the
coordinate system.
9 The instruction tried to execute in a direction that aggravates the current
overtravel condition.
Overtravel Condition
10 The master axis reference is the same as the slave axis reference or the Master
Axis is also an axis in the Save Coordinate System.
