Movement
monitoring error in
<axis> A
 The axis is moving at least 4 times slower or
faster than commanded by the nominal
speed command output.
 Large backlash
 Overloaded driver
 Insufficient lubrication
 Mechanical stiffness
 Machine vibration
 For analog axes: Servo defective
 Check machine parameter 1140.x.
 Remove any large backlash.
 Check the lubrication
 Remove mechanical stiffness
 Analog axes: Check the servo
 Inform your service agency.
 See “Sequence for Finding Errors in the
Control Loop” on page 6 – 62.
Movement
monitoring error in
<axis> B
 The motor is moving while the axis slides
are stationary or vice versa.
 Excessive difference between the positions
calculated from the position encoder pulses
and the speed encoder pulses.
 Excessive backlash
 Defective coupling, gear, etc.
 Belt torn
 Check MP1144.x
 Check the backlash
 Repair the defective coupling, gear, etc.
 Replace the belt
 Inform your service agency.
