Start-up UA05
Reference point
At every start-up after the mains have been interrupted, the reference
point of the axis must be referred again (see "Reference point and
mechanical stops"). After the reference point is reached, the axis begins
to carry out the movements set on the axis control unit.
Before the axis is put into operation, the front stroke limit must be set on
the axis control unit (see therefore the corresponding axis control unit
operating manual)!
ATTENTION
Incorrect setting of the stroke limit will cause damages to the axis,
to the booth or to the applicators
► Before connecting or switching on the axis, read carefully these
operating instructions!
► See the user manual of the axis control unit!
Setting values/parameters
The exact setting of parameters is performed with the Magic Control
CM40/CM30 control unit (see therefore the corresponding operating
manual).
The pressure for the blow-off device should be approximately 2 bar.
Reference point and mechanical stop
The reference point serves as starting point for the reciprocator control
unit for calculating the front and rear reversing point and the maximum
stroke.
Each time the reciprocator is switched on, the control unit requests that
the linear guide unit travels to the reference point (zero point). The linear
guide unit travels to the mechanical stop, and remains in this end position.
The control unit notes this and gives the distance how far the unit must
travel from this position. The standard value for the UA axis is 10, that
means 10 mm away from the mechanical stop. For this reason, the Axis
control unit must be programmed in such a way that the reference point is
always 10 mm before the lowest mechanical stop (zero point).
ATTENTION
Damages to the booth, to the gun holders etc.
Reference point incorrectly set
► Check the reference point before the first start-up and if
necessary, reset!
► Fit the mechanical stop to the gun slots!
