Description
P441
Source for crawling setpoint
*
Selection of connector to be injected as the crawling setpoint
(G130)
0 = connector K0000
1 = connector K0001
etc.
P442
Source for selection of ramp-function generator bypass
*
Selection as to whether or not ramp-function generator must be bypassed
when the crawling setpoint is injected.
(G130)
The ramp-function generator is bypassed if the AND operation between the
binector selected via an index of P440 and the setting in the same index of
P442 produces a log. "1".
P443
Source for standard setpoint
*
Selection of the connector to be applied if crawling-setpoint injection is not
FDS
selected
0 = connector K0000
(G130)
1 = connector K0001
etc.
P444
Source for standstill command
*
Selection of the binector to control the standstill operation (OFF1) or
BDS
resetting of crawling setpoint injection when P445=1 (log. "0" state = reset).
0 = binector B0000
(G130)
1 = binector B0001
etc.
P445
Selection of level/edge for switch-on/crawling
*
Selection to define whether ON command must be input via terminal 37 and
the crawling setpoint injected in response to a log. "1" level or to a 0 → 1
(G130)
transition
0
ON with log. "1" state at terminal 37 and
injection of crawling setpoint with binectors selected in P440 in
log. "1" state
ON in response to 0 → 1 transition at terminal 37 and
1
injection of crawling setpoint in response to 0 → 1 transition of
binectors selected in P440
With this setting, the ON command or injection command for the
crawling setpoint is stored. The memory is reset when the
binector selected in P444 switches to the log. "0" state.

10.22 Position sensing with pulse encoder

See parameters P140 to P148 for pulse encoder definition and monitoring
P450
Resetting of position counter
*
0
Reset position counter OFF
FDS
1
Reset position counter with zero marker
2
Reset position counter with zero marker when LOW signal is
(G145)
applied to terminal 39
3
Reset position counter when LOW signal is applied to terminal
39
Note: Counter resetting with P450 = 2 and 3 is executed in the hardware
and is not affected by how the binectors controlled by terminal 39 are
interconnected
P451
Position counter hysteresis
*
0
Hysteresis for rotational direction reversal OFF
FDS
1
Hysteresis for rotational direction reversal ON (the first pulse
encoder input pulse after a change in rotational direction is not
(G145)
counted)
P452
Source for "Reset position counter" command
*
Selection of binector to control resetting of the position counter.
BDS
0 = binector B0000
(G145)
1 = binector B0001
etc.
