Counting mode
This parameter assigns either „ascending“ or „descending” counted values in relation to the shaft’s direction of
rotation. Following parameters are available:
00 = Up
Clockwise rotation, ascending counted values
01 = Down
Clockwise rotation, descending counted values
Arrows
This parameter relates to the arrows in the display that indicate the operator the direction (to the right or to the left)
of the new positioning operation. Following parameters are available:
00 = Up
If actual value < target = arrow to the right; actual value > target = arrow to the left
01 = Down
As „Up“, but inverted arrows direction
10 = Uni
If actual value
≠
target arrows ever indicated
11 = Off
Arrows ever hidden
Note: A loop operation (as backlash compensation) is only performed with settings
Up
and
Down
.
Uni
and
Off
always implicate a direct movement to the target without backlash compensation.
Rounding the actual value
This means that the actual value being within the tolerances but still differing from the target is rounded up or
down to the target value as soon as the shaft remains idle for approx. 3 seconds. The rounding operation is only
visualized, the true internal actual value remains unchanged. For actual value readout by serial interface
(command “R”) the true, not rounded actual position value is provided. The true actual value will immediately
reappear on the display upon key actuation. If the position is still within the tolerance window the rounding
operation will be repeated after 3 seconds.
Note: In operating mode „Suppress target = Ever“ the target is deactivated and the SPA serves as pure actual
value display with disabled rounding function. The following parameters are available:
0 = Off
Round actual value disable
1 = On
Round actual value enable
Turn display
This parameter is utilized to turn the display by 180°.
0 = Off
Display readout with standard mounting, i.e. display above keypad
1 = On
Display readout with inverted mounting, i.e. display below keypad
Dimension
Only in conjunction with N 242 master. By this parameter the master enables indication of actual value and direct
positioning (so-called dimension). Refer also to N 242 user manual.
Utilized with other controls (PLC or PC) this parameter may be assigned to general identifications.
0 = Off
Device not indicated in N 242 master
1 = On
Device indicated in N 242 master. Direct target input possible
Offset
Command „U“ is utilized for programming the offset that is added to actual value and actual target. This parameter
defines whether the offset is considered in the calculation.
0 = Off
Offset disabled. Any offset previously transmitted is NOT added neither to actual value nor target.
1 = On
Offset enabled. Offset is added to actual value and actual target.
2 = On + Key As setting 1. The offset can be altered by keypad.
Suppress target
This parameter defines when to indicate the target in the upper line of the display.
0 = On
Target indicated if target
≠
current value.
1 = Off
Target ever indicated, also if target = current value. Indicate arrows too if target
≠
current value.
2 = Ever
Target and arrows ever suppressed.
