Troubleshooting

Malfunction Possible cause
Reversing play Wear in lead screw
too great
(è Tab. 5)
Running Tension
noises or
vibrations
Incorrect regulator settings
Wear
Piston rod Jamming in mechanical end
does not move position (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
viscosity of the lubricants in
the spindle system)
Wear on ball drive

Remedy
Replace the ESBF-LS
Install ESBF so it is free of tension
(evenness of the bearing surface: ≤ 0.2 mm)
Lubricate the piston rod (è 7 Maintenance and
care)
Modify travel speed
Change the controller parameters (only on servo
systems)
Replace ESBF-BS
– 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
(è Assembly instructions for the parallel kit)
– Reduce effective load
– Reduce travel speed
– In the case of servo motors, it may be necessary
to allow higher peak current
(è Operating instructions for the motor)
– Adjust ambient temperature
– Interpose gearbox to generate higher torque
With interposed gearbox
– Adapt lubricant
Replace ESBF-BS
