8.2 Fault causes and remedy
The following table contains an overview of possible fault causes and how to
proceed to eliminate them.
Malfunctions when returning to reference position
Fault
Possible cause
Remedy:
The telescope spindle axis
oscillates (very strong
vibrations at the drive)
Control parameters incorrectly
adjusted
Readjust the parameters on the
controller
Telescope spindle axis moves
to retracted end position and
stops
Reference sensor incorrectly
connected
Reference sensor disconnection
Reference sensor defective
Check terminal assignment and
correct if necessary
Check reference sensor cable
Send telescope spindle axis to
manufacturer AFAG!!
Telescope spindle axis moves
to end position and stops
Incorrect homing (reference)
direction
Check homing (reference) direction
and change if necessary
Telescope spindle axis does
not move
Drive incorrectly connected
Motor disconnection
Drive defective
Check terminal assignment and
correct if necessary
Carry out function check
Check motor cable
Have the drive replaced by AFAG
Malfunction during operation
Fault
Possible cause
Remedy:
The telescope spindle axis
oscillates (very strong
vibrations at the drive)
Control parameters incorrectly
adjusted
Readjust the parameters on the
controller
Telescope spindle axis stops
after short stroke
Significant contouring error
Interruption in the resolver
connection
Reduce values for acceleration and
speed
Check if telescope spindle axis is
mechanically blocked
Check encoder cable
Check encoder for function
Increased toothed belt noise
Toothed belt tension incorrect
Toothed belt defective
Check toothed belt tension and
retighten toothed belt if necessary
Replace damaged toothed belt
Increased running noises on
the module
Spindle lubrication not OK
Axial play in the spindle gear
Marked play in the guide of the
module
Re-lubricate the spindle
Have spindle gear replaced by
AFAG!
Have the telescope spindle axis
replaced by AFAG!
