Description
An internal system error has occurred.
(<TO>.ErrorWord.X0 (SystemFault))
Configuration error
One or more configuration parameters are inconsistent or invalid.
The technology object was incorrectly configured, or editable configuration data were
incorrectly modified during runtime of the user program.
(<TO>.ErrorWord.X1 (ConfigurationFault))
Error in the user program in a Motion Control instruction, or in its utilization.
(<TO>.ErrorWord.X2 (UserFault))
Error in the drive.
(<TO>.ErrorWord.X4 (DriveFault))
Error in the encoder system.
(<TO>.ErrorWord.X5 (SensorFault))
Error in communication with a connected device.
(<TO>.ErrorWord.X7 (CommunicationFault))
Error accessing a logical address.
(<TO>.ErrorWord.X13 (PeripheralError))
Command cannot be executed.
A Motion Control instruction cannot be executed because the necessary conditions have
not been fulfilled (e.g. technology object not homed).
(<TO>.ErrorWord.X3 (CommandNotAccepted))
Error during a homing process.
(<TO>.ErrorWord.X10 HomingFault))
The axis was not correctly positioned at the end of a positioning motion.
(<TO>.ErrorWord.X12 (PositioningFault))
Dynamic values were limited to the dynamic limits.
(<TO>.ErrorWord.X6 (DynamicError))
The maximum permitted following error was exceeded.
(<TO>.ErrorWord.X11 (FollowingErrorFault))
A software limit switch has been reached.
(<TO>.ErrorWord.X8 (SwLimit))
A hardware limit switch has been reached or overshot.
(<TO>.ErrorWord.X9 (HWLimit))
Synchronous axis only
Error during synchronous operation. The leading axis specified at the Motion Control in-
struction "MC_GearIn" was not configured as a possible leading axis.
(<TO>.ErrorWord.X14 (SynchronousError))
