'rctive digital position readout unit, c-ont'd
Positioning
First set at least one reference point with or without refer'
ence mark evaluation. The position readout will count from
the momentary reference Point.
ln'manual'mode Sl
Use handwheel or pow.er feed to move machine slide(s).
Feed motions
- Operate 'Feed'keY @.
- Operate both feed buttons on operator panel and rapid
traverse but in addition, if required.
Automatic positioning
,odes:'absolute dimensions';
'incremental (chain) dimensions'.
Absolute d imensions: all dimensions, including setpoints,
refer to the reference point in the axis concerned.
lncremental (chain) dimensions: each dimension refers to
the last previous actual position. Setpoint values will be
keyed in as chain dimensions, but actual-value readouts
show absolute dimensions.
Starting situation: 'manual' mode, necessary reference
points already set.
Preparing the positioning operation
- lf 'REF' lamp (6) is still illuminated, operate 'REF' key
to extinguish LED.
- Operate mode key E otE.
- Set feed rate o,n operator control panel and operate feed
buttons.
rosltlOnlng
- Operate CE key (1)
{not required if previous preset value has already been
transfered to an actual-value counter).
- Key in setpoint value on keyboard (1 ) in either absolute
or chain dimensions. depending on mode selected.
- Operate transfer key X, Y or Z (21 .
- Engage feed control lever in accordance with external
axis and direction indicator (Fig 3): axis will start mov-
ing and stop in setpoint position.
- Disengage feed control lever (move lever to middle posi-
tion).
Any positioning operation can be interrupted by means of
El n.t (131. To resume the positioning operation, again
operate transfer key in the axis concerned.
To change the direction of a motion, disengage feed control
t.ver, key in new position and then operate transfer key in
,e axis concerned.

lmportant
lf a 'chain dimension' positioning operation is interrupted
by means of 'stop' button (13), the actual position at that
point will be the reference point for the next positioning
operation in chain dimension.

The external axis and direction indicator (Fig 3) is con-
nected in parallel with the digital readout unit. lt shows
the operator the direction of feed selected and thus indi-
cates which feed control lever has to be moved in what
direction.
lmportant
Always move all feed control levers to zero position before
any change in mode or operating any of the transfer keys
X,Y,Z.
