Malfunction
Possible cause Remedy
Uneven movement of the
payload
Flow control valves inserted
incorrectly
Check the flow control
function (supply o r exhaust air
flow control)
Asymmetric angle setting Symmetric setting preferred
DRRD defective Return to Festo
Hard metal impact at the end
position
Flanged shaft do es not remain
in the end position
(rebounding)
Residual energy too high Select a lower swivel speed
Move only against residual air
cushionontheexhaustside
Select a lighter load
Semi-rotary drive moves
against an unpressurized
chamber
Pressurize semi-rotary drive
on bo th sides
Shock absorber unscrewed
too far
Observe the maximum
permissible unscrewing length
Cushioning component
defective/worn
Replace cushioning component
