2.17.1. Overview

The UhlText is a plugin, which can be used to control the 2-4 axis stepper motor devices from Uhl (F9S-x) and Lang LSTEP 2x It is initialized by actuator(“UhlText”, SerialIO, …).

WARNING: There are different controller versions with different command languages. This DLL is for devices that are controlled by ASCII commands via the RS232 port. WARNING: The calibration direction of the stages differs according to motor / controller. Check calibration direction before usage.
