6.7 Finding Position Differences of Direct and Indirect Encoder
This procedure serves to compare the signals of the motor encoder to those of the position
encoder.
This allows to draw conclusions about the quality of the mechanics and the coupling system.
Prerequisite The machine tool to be investigated must be equipped with digital drives and direct
encoders (dual encoder system).
These instructions do not apply for digital axes with linear motors.
Integrated
oscilloscope
The integrated oscilloscope features the Pos. Diff. signal (difference between position and
speed encoder in mm).
Activation and operation --> See “Integrated Oscilloscope” on page 10 – 99.
An example of recording a position difference:
8 Make the following settings:
8 Use a NC program which moves the X-axis back and forth several times. (Ask the
machine operator.)
8 Start the program and start oscilloscope recording.
8 Stop recording and adjust the signals.
