Errors in the Motion Control Function Module

The section provides tables of the errors (events) that can occur in the Motion Control Function Module.
They are divided into the following functional classifications.
• General motion control
• Motion control instructions
Motion control instruction errors occur when a motion control instruction is executed. Notification of
these errors is provided as events, but also the upper four digits of the event code is output to the
ErrorID output variable of the motion control instruction and to the *.Lvl.Code system-defined variable
for motion control.
