Troubleshooting

Malfunction
Possible cause
Axial play too Wear
large
Running Tension
noises or
vibrations
Incorrect regulator settings
Piston rod Jamming in mechanical end posi-
does not move tion (e.g. after homing at too
high a speed or after improper
travel into an end position during
operation)
Loads too high
When using the parallel kit, the
pretension on the toothed belt is
too high
Ambient temperature too low
(increased breakaway torque in
initial run due to increasing vis-
cosity of the lubricants in the
spindle system)

Remedy
Send the ESBF to Festo for repairs
Install ESBF so it is free of tension
(evenness of the bearing surface: ≤ 0.2 mm)
Lubricate the piston rod (
care)
Modify travel speed
Change the regulator parameters
(only with servo motors)
– 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)
– Reduce effective load
– Reduce travel speed
– Send the ESBF to Festo for repairs
Reduce the pretension on the toothed belt
( assembly instructions for the parallel kit)
– 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
