Motion Error Codes, faults, and attributes

70  Look for source or target axes that are configured as rotary positioning mode. 
Change them to linear positioning mode. 
Axes In Transform Must Be Linear 
A transform works only with linear axes. 
71  Wait until the transform that you are canceling is completely canceled.  Transform Is Canceling 
72 
Check the target positions. A calculated joint angle is beyond +/- 360
. 
Max Joint Angle Exceeded 
73  Check that each MCT instruction in this chain is producing valid positions.  Coordinate System Chaining Error 
This MCT instruction is part of a chain of MCT instructions. There is a problem with 
one of the instructions in the chain. 
74 
Change the orientation to angles that are within +/- 360
. 
Invalid Orientation Angle 
75  Use this instruction only with a 1756-L6x controller.  Instruction Not Supported 
You can use an MCT or MCTP instruction only with a 1756-L6x controller. 
76  You cannot start motion that uses an S-curve profile if the maximum 
deceleration jerk for the axis is zero. 
1. Open the properties for the axis. 
2. On the Planner tab, enter a value for the Maximum Deceleration Jerk. 
Zero Max Decel Jerk 
 
77  How many axes are in your coordinate system? 
2 — Use a non-mirror transform direction. 
3 — Use a non-inverse transform direction. 
Transform Direction Not Supported 
You're trying to use the mirror directions with a 3-axis coordinate system and a 
non-zero base offset (X2b) or effector offset (X2e). 
Mirror directions are not supported for 2-axis Coordinate Systems. 
You are attempting to use either a 2 or 3-axis Cartesian, Delta2D, Delta3D or 
SCARA Delta target coordinate system with transform directions other than 
forward and inverse. 
You can use inverse mirror directions only when both these conditions are true: 
You have a 3-axis coordinate system. 
The base offset (X2b) and end effector offset (X2e) of the X2 dimension are zero. 
78  New check for a secondary Instruction overlap on top of an active Stop 
instruction. 
Not Allowed While Stopping 
You cannot overlap certain Motion instructions while stopping. Wait for the first 
instruction to complete before starting the second instruction. 
79  Home your axis again. 
Error of Home instruction occurs, if any other motion on the axis is encountered 
during the homing sequence. 
Internal Homing Sequence Error 
Invalid Planner State 
If you see this error, rehome your axis in your application program. Make sure the 
axis is stopped before home is attempted. If the error persists, contact Rockwell 
Automation Support. 
80  When referencing a Scheduled Output Module, for example, the OB16IS, make 
sure that the Output operand of the MAOC references O:Data, and that the 
Scheduled Output Module's communication format is set to `Scheduled Output 
Data per point’. 
 
 
MAOC Invalid Output Operand 
If the MAOC output operand references an OB16IS Scheduled Output module, two 
additional checks occur when the MAOC is initiated. 
The Output operand must be referencing the beginning of the module’s output 
data tag, 'O.Data'. 
The communications format of the OB16IS module must be the default 
"Scheduled Output Data per Point". 
If either of these checks fail you see this error. 
ExErr#1: Invalid Data Tag Reference - The Output operand is not pointing to the 
O.Data element of the module’s output data tag. This is applicable to 5069-OB16F, 
1756-OB16IEFS, 1732E-OB8M8SR, and OB16IS modules only. 
ExErr#2: Invalid Module Communication Format for one of these modules: 
5069-OB16F, 1756-OB16IEFS, 1756-OB16IS, 1732E-OB8M8SR modules. 
ExErr#3: CIP Sync not synchronized - Scheduled output module reporting not 
synchronized to a CIP Sync master. Applicable to the 5069-OB16F, 1756-OB16IEFS, 
1732E-OB8M8SR modules only. 
ExErr#4: Grandmaster Clock mismatch - Scheduled output module has different 
Grandmaster clock than the controller. Applicable to the 5069-OB16F, 
1756-OB16IEFS, 1732E-OB8M8SR modules only.
