Assignment of output leads by the SIPLACE Axis tester and connection to the oscilloscope.
The axis dynamics of the Z axis are checked with a continuous run in free space. A motor current signal
is transmitted at the V nominal output. The uncommutated current signal (signal 3) shows the friction for
the axis system. The current signal amplitude increases as the friction rises.
The positioning time for the Z axis is 84 ms +/-2 ms.
