4.4 Instructions on operation
Warning
Damge may occur if maximum permitted limits, such as
mass loads, mass moments of inertia, swivel frequencies
etc. are exceeded. Make sure that the maximum specified
limits of the drive used are observed (see operating in-
structions for the relevant drive).
Warning
In order to avoid damage due to uncushioned movement
into the end positions:
S Always carry out the teach procedure again after adjust-
ing the fixed stops or when components and tubing have
been replaced.
S Observe the permitted mass loa d.
Warning
In order to avoid undesired movements of the actuators,
always proceed as follows:
If there is no positioning order when the power supply is
switched on and if the moveable mass is not at one of the end
positions, the valve slide will remain in the electrical mid-posi-
tion. Due to the asymmetrical voltage-pressure curve of the
proportional directional control valve, the slide can now move
slowly into one of the end positions.
Switching on
S Always switch on first the operating voltage supply and
then the compressed air supply.
