Adjusting the offset
Connect the axis testing device to the axis board. Select the axis on the axis testing device (2 or 3).
Change the MA data for adjusting the offset using the values in the table 10.3.1.
Then reference the axis.
Use the offset potentiometer on the servo board to set the axis position to 0 ± 1 digits.
Check: the position display must not deviate from the value 0 by more than 1 digit.
Setting the speed
Change the MA data for setting the tacho using the values in the table 10.3.2.
Then reference the axis.
Set the axis testing device to time measurement (set the toggle switch to -1) and set the rotary switch for
axis 0 to 1.
Start the axis in continuous mode. Distance: 0 to 2,800 digits.
Increase the P gain on the servo board until the axis can be easily positioned.
Use the tacho potentiometer on the servo board to set the end message signal to 119 ms ± 5 ms.
Check: the positioning time must be 119 ms ± 5 ms (measured with a suitable P gain).
Adjusting the P gain
Set the MA data as for setting the tacho.
Start the axis in continuous mode. Distance: 0 to 2,800 digits.
Use the ratio potentiometer on the servo board to increase the P gain until a slight tendency to vibrate can
be seen on the current curve.
Increase/reduce the P gain until the position deviation no longer dips or rises (see Fig. 10.3.13 to Fig.
10.3.14).
Use the tacho potentiometer on the servo board to adjust the speed to 119 ms ± 5 ms.
Check: Start the axis in continuous mode. Distance: 0 to 2,800 digits.
- The P gain must be set so that the position deviation no longer dips or rises.
- For a distance of 0 to 2,800 digits, the positioning time must be 119 ms ± 5 ms.
Checking the positioning quality in accordance with table 10.3.4
Reset the MA data to the basic data and reference the axis.
Start the axis in continuous mode. Distance: 0 to 2,800 digits.
50 ms after the end signal, the position deviation must not exceed 2 digits.
Checking the offset
See "Adjusting the offset".
Reset the MA data to basic data (see Table 10.3.4) and reference the axis (all axes).

Check:
Set the positioning distance to 120,000-280,000 and 100,000-300,000.
The position deviation and current curve must not rise for either distance.
During the reference sequence, the axis must not rise or give off a loud humming noise.
The positioning time for the distance 120,000 to 280,000 must be 815 ms ±10 ms.
The positioning time for the distance 100,000 to 300,000 must be 980 ms
±
10 ms.
Positioning quality
Preparation:
Reset the MA data to basic data (see Table 10.3.4) and reference the axis.
Set the distance in accordance with the distance table (see Table 10.3.9) and check the position
deviation.
50ms after the end signal, the position deviation must not exceed 5 digits.
Check:
Set the distance in accordance with the distance table and check the time. Check the settings and
the machine, if necessary.
The end signal will not be output until the post-pulse oscillations in the position deviation have
fallen below the specified value (position deviation in REAL.MA), since this could cause signifi-
cant fluctuations in the positioning time.
