16.3.4 Testing the direction of traverse
Test the controls for the direction of traverse according to the following diagram (effective machine
parameters: MP210 count direction of the measuring system signals, MP1040 polarity of the
nominal value voltage, MP1320 direction of traverse on passing over the reference marks).
