11 Troubleshooting
Malfunction Possible cause Remedy
Axial play too
large
Wear Send the ESBF to Festo for repairs
Running
noises or
vibrations
Tension Install ESBF so it is free of tension
(evenness of the bearing surface: ≤ 0.2 mm)
Lubricate the piston rod ( 8 Maintenance and
care)
Modify travel speed
Incorrect regulator settings Change the regulator parameters
(only with servo motors)
Piston rod
does not move
Jamming in mechanical end posi-
tion (e.g. after homing at too
high a speed or after improper
travel into an end position during
operation)
– To release a jam manually:
1. Switch off power,
2. Remove motor and coupling housing,
3. Turn drive shaft to release it
– Reduce speed for reference travel
– Set software end positions at least 0.25 mm
away from the mechanical end positions
(the stops)
Loads too high – Reduce effective load
– Reduce travel speed
– Send the ESBF to Festo for repairs
When using the parallel kit, the
pretension on the toothed belt is
too high
Reduce the pretension on the toothed belt
( assembly instructions for the parallel kit)
Ambient temperature too low
(increased breakaway torque in
initial run due to increasing vis-
cosity of the lubricants in the
spindle system)
– Reduce effective load
– Reduce travel speed
– In the case of servo motors, it may be neces-
sary to allow higher peak current
( operating instructions for the motor)
– Adjust ambient temperature
