Arm Movement Failed

Error ID: 4002
The transport assembly was unable to complete a movement in one of the
axes.
The processor defines a certain time window for the successful completion of
a movement in any particular axis. The movement and position of the
transport assembly is monitored by the encoders on the stepper motors. If the
processor does not receive the correct position information from the encoders
within the time window, the error message is generated.
