I.. Posi. Machine
Para. No. Description
I30
Continuation
3: define home
;
BE function
"24:Start ref."
or "
J05
→
1" immediately sets the actual position to
I34
without
performing an additional movement. For example, this can be used to set the actual position to zero at all
times (enable must be active).
4: posi.start
;
Each
posi.start
signal causes reference position
I34
to be set. This can be used, for example, to
indicate the actual distance as the current position with relative positioning and offset of the traversing path
via analog signal (
"1:additional reference value“
and
"4:reference value-faktor“
).
I31
Reference direction:
Initial direction to take when searching for the reference point. Cf. chapter 10.6.
If only one direction is permitted (
I04
>0), the reference traversing direction depends on
I04
and not
I31
.
0: positive;
1: negative;
I32
Reference speed fast:
Speed for the first phase of reference point traversing (i.e., determining the rough area).
Omitted when only one direction of rotation (
I04
) is permitted. Only the slow speed (
I33
) is then used for this
type of reference point traversing.
Value range in I05/sec:
0 to 90 to 31 bits
I33
Reference speed slow:
Speed for the final phase of reference point traversing. Switching between
I32
and
I33
is automatic. Cf. figures in chapter 10.6 The acceleration during reference point traversing is
I11
/2.
Value range in I05/sec:
0 to 4.5 to 31 bits
I34
Reference position:
Value which is loaded to the reference point (e.g., provided by the reference switch or the
stop switch) as the actual position. The drive stops after reference point traversing. The position is determined
by brake ramp
I11
/2. Cf. chapter 10.6.
Value range in I05:
-31 bits to 0 to 31 bits
I35
Ref.encoder signal 0:
Only if
I36
=0 and
I30
≠
2. Referencing to zero pulse of an incremental encoder.
0: inactive;
Zero pulse is not evaluated. Referencing to the edge of the stop or reference switch. Important for
continuous axes with transmissions, for example. Also useful when there are not enough binary inputs and
demands on accuracy are not high.
1: active;
Standard for precision drives. Zero track must be connected.
I36
Continuous reference:
Only for continuous axes (
I31
=1). Used for fully automatic compensation of slip or
inexact gear ratio. After the reference points are traversed for the first time, actual position
I80
is always
overwritten with reference position
I34
each time the reference switch is passed over in direction
I31
(but only in
this direction!). Since the path which is still to be traversed is corrected, the axis is able to perform any number
of relative movements in one direction without drifting, even when drives have slip. If the reference switch is
connected to BE3, the signal is processed immediately.
Remember:
When
I36
=1, the other edge of the reference switch is evaluated than for
I36
=0 during reference
point traversing. Circular length
I01
must be as close as possible to the path between two reference signals
(e.g., after one belt rotation, the same position must be indicated). Check actual position
I80
during a rotation
with
I36
=0, and adjust
I07
if necessary. The distance per rotation
I07
must always be rounded to the next higher
number to prevent undesired counterclockwise offsets. The reference switch should not be triggered during a
deceleration ramp since a negative offset would cause a counterclockwise movement.
Important
: Target window
I22
must be greater than the maximum physical inaccuracy!
0: inactive;
1: active;
I37
Power-on reference:
Automatic reference point traversing after power-on.
0: inactive;
1: posi.start;
After power-on, the inverter assumes operating mode
"24:ref.wait."
The first
posi.start
or
posi.stop
signal starts the reference point traversing procedure.
2: automatic;
Reference point traversing is started automatically as soon as the enable appears.
I38
Reference block:
Number of the process block (i.e., 1 to 8) which is to be automatically started at the end of
reference point traversing. This can be used to put the drive into a defined position after the reference points
have been traversed.
Speed and acceleration are taken by process block
I38
.
0: standstill. No automatic start.
1 to 8:
Number of the process block to be executed.
I40
Posi.-step memory:
Helpful during relative positioning of continuous axes.
0: inactive;
Posi.step
signals during a movement are ignored.
1: no stop;
Posi.step
signals which arrive during a movement cause the current destination position to be
changed immediately. The process block specified by the reference block or, if no reference block is defined,
the currently selected process block takes over. Example: Two additional
posi.step
signals arrive during a
relative movement of 100 mm. The drive then moves precisely 300 mm without stopping.
