The VSD-E and VSD-XE drives are effortlessly configured by using freely downloadable GDtool software. GDtool is a Windows software where all drive parameters can be easily set trough graphical user interface. Drive parametrization and servo tuning can be do done in matter of minutes with help of testing and scope view features.

• All parameters fully graphically configurable, no jumpers or trimpots
• Connects directly to drive through USB
• Advanced test & tuning tools
• Scope view to eliminate physical oscilloscope
• Easy replication or distribution of parameters in industry use
• Save test results & parameters for remote technical support

SimpleMotion is maximally simplified but still capable motion control library to control VSD-E/XE drives on PC. SimpleMotion allows implementing point-to-point positioning application with single line of code. The SimpleMotion DLL library is designed to integrate easily on most programming environments such as C, C++, C#, LabVIEW, VisualBasic and Matlab.

• The simplest motion control interface in the world
• No initialization code needed - connection is established when needed first time
• Connects directly to drive through USB - no other interface hardware needed
• Control position, velocity or torque
• Query axis status, clear faults, enable/disable, do referencing/homing etc
• Set and read drive parameters on the fly
• Point-to-point motion with adjustable velocity/acceleration profile
• No parameterization code needed - all parameters settable via GDtool
