"""
Continuous 1D Manipulator scan

set manipulator scan parameters below.
set analyser parameters in the scienta window. recommended: fixed mode, dwell time between 0.2 and 1.0 s

the motor speed is determined from the STEP parameter and the scienta busy time (dwell time + dead time).
note that the motors have a limited speed range!
