VSA Series Digital PWM Servo Amplifiers

Varedan has a long history of providing reliable high performance linear servo amplifiers for OEM customers. Following that tradition, the VSA Digital PWM Servo Amplifier line extend our product offerings to include advanced digital controls, efficient power delivery, compact footprint, and simple to use tuning and configuration utilities while retaining the reputation for superior reliability and performance.

The VSA1 and VSA2 series feature a powerful microprocessor to provide reliable, high-precision motor control, stored motion profiles, and real-time scope functionality. These amplifiers also feature all standard modes of operation, from current (torque) mode to position mode, and includes external sine commutation mode for compatibility with advanced controllers and legacy applications. All standard forms of encoder feedback plus an auxiliary quadrature port can be utilized, giving the user the highest level of flexibility and freedom.

Easy to Use Graphical User Interface

The PC based VaredanGUI™, with it’s built in command stimulus and real time oscilloscope signal tracer views, reduces the requirements for external equipment while setting up new systems. The standard Ethernet based communications easily connects with all modern computers. Full system configuration can be saved and uploaded for quick and easy drive provisioning.
