StepDrive
The StepDrive motor system is a mechanical rough-fine drive system, which gives high turning
speeds and accuracy. The system provides endless horizontal and vertical motion, including endless
fine adjustment. The instrument uses a StepDrive motor system when performing a number of
different operations such as turning the horizontal and vertical motion knobs, for automatic test and
calibration, or when using LockNGo Tracker technology for robotic surveying, see image below.
Please see also Settings for Drive Mode:, page 61.
