2.3 Setting Datum/Reference
Datum can be set in a variety of ways. The method is selected in Register R8/3
R8 = XX0XXX – Datum to R7
With activating the external input ST3 Pin 8 (X- Axis) or ST3 Pin 7 (Y- Axis), the
value deposited in R7, will be taken over into the actual position window.
R8 = XX1XXX – Datum to preset (target value)
With activating the external input ST3 Pin 8 (X- Axis) or ST3 Pin 7 (Y- Axis), the
actual target value will be taken over into the actual position window (single mode
only).
R8 = XX4XXX – Datum directly to R7 (without external reference input)
2.4 Encoder pulse monitoring
There are a number of faults on a machine that can stop the operation i.e.
Stalled motor, Controller failure, Cable failure, Encoder failure
Should pulses fail to reach the controller after start has been given and before in posi-
tion is reached, then one of the above faults must be present. The controller monitors
the pulses at intervals set in Register R19 X/Y. If the Register R19 X/Y is set to "0",
the monitoring features will be disabled. Should a failure occur, the ERROR01 is dis-
played in target position window.
2.5 Error messages
If any failures are present, the following error numbers flashes in the target value win-
dow.
Error number 01 = Encoder error
02 = End Limit minimum active
03 = End Limit maximum active
04 = Actual position < min software limit (R13) Hand
Target position < min software limit (R13) Single
05 = Actual position > max software limit (R14) Hand
Target position > max software limit (R14) Single
07* = External stop activated or wire break
08 = Maximum number of program lines exceeded
The fault message is cleared by pressing any button.
“07” also flashes if Stop on front panel is activated in middle of any move.
*Notice for 07: The external STOP input must be linked before system can oper-
ate. Therefore, if external n/c pushbutton is not fitted, then insert a permanent
wire link. Thus the stop input can be used as wire break input.

7. Description of Registers
R01 - Slow speed distance X/Y
Distance to the target position at which the controller switches from high speed to slow
speed. The output high speed will be switched off.
R02 - Creep speed distance X/Y
Distance to the target position at which the controller switches from slow to creep speed
R03 - Stop offset distance X/Y
The over run distance can be programmed to compensate for distance from the switch-
off point of the motor to standstill. For exact positioning, the over run distance should be
very small (0.0… 0.5 mm). Therefore the mechanical friction should be steady and the
creep speed should be very slow.
During commissioning, first set R12 to zero (to eliminate Tolerance window blanking),
then set the value of R03 to 0.0 and execute a number of moves in both directions.
Note
the average overrun distance and then set R03 to that value. Then set R12 to suit.
Note: Stop offset is only functional when R8/1 = 1
R04 - Backlash overrun X/Y
To correct for screw or pinion backlash, the target position should be approached
from one direction only. In positive direction therefore, the target position will be
overrun by the value of R4 and drive back to the target position with creep speed,
after the time delay of R10.
R05 - Retract distance X/Y
There are different modes available in the P8822, selectable by Register R18/2.
If R18/2 = 0 Retract Position to the actual value + R5
Whilst the input St3 Pin 7 (Y- Axis) resp. 8 (X- Axis) is activated, the P8822 will move
to the retract position. With deactivating the input, the controller returns to the basic
position (Value 0).
If R18/2 = 1 Retract Position to the value of R5
When input St3/8 is activated, the axis moves to position as set in R5, but will not re-
turn to original position on release of input. (Value 1)
If R18/2 = 2 Retract with backlash dwell time of R10
R06 - Tool offset compensation X/Y
This Register can be accessed without security code. When moving in incremental mode,
it is often the case that the subsequent function is a cut, that removes part of the mate-
rial. Thus to cut the correct pre-set lengths, it is necessary to move the desired distance
plus the tool offset. This feature is active in incremental mode only.
R07 - Datum/Reference X/Y
This Register can be accessed security code. The Datum value is stored in this Register.
The value is used in different ways, in accordance with setting of P8/3. Input St3 Pin 7
(Y-Axis) resp. Pin 8 (X- Axis) initiates loading.

R9 - Time “in position”
At the end of each move, the controller gives an output, to signal “in position” as long as
the time register R9/X resp. R9/Y is. The length of this pulse is adjustable in R9
(range: 0.1… 9.9 s). Setting 0.0 gives a maintained output.
R10 - Backlash dwell time
When the machine stops at the end of the overrun, it is usually desirable to have a short
delay. The time is set in register R10 (range: 0.1… 9,9 sec.).
R12 - Tolerance window
It is possible to enter a value in Register R12 that represents an acceptable tolerance
e.g. 0.1 mm. When the actual position is within the tolerance window, the actual position
displayed is made equal to the Target position. The actual error is not lost, as the con-
troller knows the true position.
Example: R12 = 0.2 Therefore tolerance window is +/- 0.2mm
Display without tolerance set Display with tolerance set
Note: At first start-up, the tolerance window is to be set first to “0”.
Only after a correct adjustment of R1… R4, other values can be used here.
R13/ R14 - Min/Max software limits
Target < Limit R13 = error message ERR04
Target > Limit R14 = error message ERR05
Single operation
Immediately after a start signal, the controller checks the software limits. If the target
position is greater or smaller than the corresponding limit, the controller will stop and
show the error message on the display. The backlash distance in R4 is considered at the
check of the Max software limit, if the backlash is activated in R8/6 X/Y.
Manual operation
The movement will stop when software limits are reached. If moving at high speed, the
drive will drop to creep speed at a distance set in R1 from this limit. This prevents run-
ning into the ends of the machine. The end limit values are modified by backlash value
as set in R4, if R8/6 X/Y is selected.
R15 - Software Limit Selection

R29 Time delay for drive inhibit (positioning)
On activating start, output positioning is activated. On arriving in position, after a time
delay of R29 this output deactivates.
R30 Time of “program end” signal
If last step of a program is completed, the output signal program-end is activated for
the time programmed in this register.
R40 Program block selection
This register can be accessed without security code (R98). The program block required
for operation can be entered here (0… 99).
R41 Number of Lines in each program block
Enter the number of lines required per program block (1 – 99). The number of Blocks
will be calculated automatically.
Example : Total number of lines = 200, Number of Lines required per Block = 25
(enter 25 into R41). Therefore number of Program blocks = 8
R46 Program cycle- pre selection
To limit the execution of the Program the cycle counter can be set. If the Register R47
(Cycle counter) is equal the pre selection the signal ready will drop off. To Disable the
counter set R46 to zero.

When the cycle counter is complete. i.e. R46 equal to R47 the output ready drop of and
cycle count is displayed in actual position window. The external and front panel Start are
disabled. To clear the output to allow positioning again R47 must be set to zero. For
temporary unlock press Stop. The one more Program cycle can be done. After complet-
ing this Program new counter value is displayed and ready drop of again.

R73 Automatic stop offset calculation and positioning retry
If the value of R73 X/Y is set to zero, the controller will operate without recalculation
and without retry. If the value of R73 X/Y is set to "1" this means that should the posi-
tion reached be outside the tolerance window, the controller will recalculate the new stop
offset but no retry. If R73 is set to any value bigger than “1” the controller will also re-
try.
R80 Two axis position comparator
Two modes are required. Anti collision control and Balance control
Setting R80: Value 0 : Checking mode inoperative
Value 1 : Anti-collision operation.
Value 2 : Skew Detection
R81 Comparator distance
Controller checks both positions whilst running and if difference is bigger than value set in
R81, stop is activated and ERROR09 / ERROR10 info is activated.
