Versatile Servo Drive VSD-A

Please notice that VSD-A is sold out and this model has been replaced by VSD-E!

VSD-A is a precision servo motor drive/controller for permanent magnet AC and DC servomotors with quadrature encoder feedback. Possible control methods include position, velocity and torque modes. Built-in trajectory planner enables simple point-to-point moves as well as continuous synchronous motion tracking.

VSD-A features industry standard optoisolated pulse/direction, quadrature and PWM inputs in addition to a device specific SPI (Serial Peripheral Interface) protocol.

Features:

DC bus supply voltage 24-200 Vdc
Peak output current 15.0 A (¹
Maximum stall current 10.0 A (¹
Field oriented flux vector control for higher bandwidth
Position, velocity and torque modes
Supported motors: permanent magnet DC, AC (sinusoidal)
AC servo motor phasing without hall sensors
Quadrature encoder feedback (differential line outputs)
Command inputs: step/direction pulses and serial commands via SPI bus
Fully optoisolated command I/O
Firmware field upgrades
PC software based tuning
Arbitrary ratio input command scaling and gearing
Trajectory planner with tunable velocity/acceleration limits
Acceleration and velocity feedforwards
Soft recovery from following error
Separate supply terminals for logic and high voltage
No loss of position on high voltage outage
Typical efficiency of 95% at full power

1) Current is measured as peak value of sinusoidal waveform

Applications

CNC machine tools
Spindle control
Automation & robotics
Pick and place machines

Benefits of True torque control

VSD-A incorporates State of the Art precision torque control in all operation modes. Torque control has numerous advantages over voltage control which can be found from the most of similar price level drives.

Easy setup

VSD-A comes with an USB cable for straightforward connection & configuration. All new GDtool 2.0 software takes guesswork out of tuning. GDtool downloads response data directly from drive and no additional equipment, like oscilloscope, are needed.
