Operation - Festo DHTG Instrucciones De Utilizacion

DHTG
For setting the cushioning:
• Loosen the clamping element (K) one rotation.
• Screw in the adjusting screw 6 until the desired cushioning
is achieved. The rotary indexing table must not strike hard
against the end stops and the overload protection must not
be triggered. The maximum moment of mass inertia must
not be exceeded.

Operation

Warning
Risk of injury from rotating masses.
• Make sure nobody can place his/her hand in
the positioning range of the DHTG and that no
objects lie in its path (e. g. by providing a
protective screen).
• Note the moment of mass inertia as a factor of the switching or cycle frequency (
curves).
– The maximum achievable switching frequency as a factor of the moment of mass inertia can be
read in the diagram Switching frequency. The switching time can be calculated from this
by T = 60/f. The response time comprises: Switching time = unlocking, turning, locking and the
return stroke of the work piston.
