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).

Positioning quality
Preparation:
● Reset the MA data to basic data (see Table 10.3.4) and reference the axis.

fallen below the specified value (position deviation in REAL.MA), since this could cause signifi-
cant fluctuations in the positioning time.
