7.6.3.3 Test setup with SAT-Box
Please Note::
For checking of the dynamics with the aid of the SAT-Box please use the official Adjustment ma-
nual. 7
Fig. 7.6 - 6 Test set up SAT-Box
Legend outputs Siplace Axis Tester to oscilloscope channels
The Axis dynamic of the Z axis is checked with continuos run in free space. At V nominal output
of the Axis tester pass a motor current signal. The uncommutated nominal current signal (Signal3)
show the friction of the axis system. If the current is increased it show also increased friction.
The positioning time for the Z axis is 84 ms +/-2ms.
(1) Nominal current (Vreg)
not connected to the scope for HF
(2) uncommutated nominal current
connect to CH2
(3) Deviation of position connect to CH1 (4) End signal connect to CH 3
