VSD-E/XE drive is a versatile servo drive from Granite Devices.

Applications

Motion control

• Robotics
• CNC
• Pick'n'place
• Precise speed,torque or position control
• Actuators
• 3D printers

Other uses

VSD-E series has been successfully used also in non-motion related applications mainly in torque mode (a.k.a. current control mode). In these applications a LC filter has been used after drive to smoothen out the PWM output.

• High power LED driver with dimming (up to 160 VDC led strings)
• High power thermoelectric cooling driver

Key features

Single axis a.k.a Evolution mode

Simplified VSD drive block diagram in position control mode.

List of key features:

• Easy setup via GDtool software
• SimpleMotion control library for PC, C/C++/C#, LabVIEW etc
• Various low level command inputs (pulse/dir, PWM, quadrature, ±10V)
• Easy connection to fieldbuses like EtherCAT or CANopen (more info)
• Most AC/BLDC/DC and linear servo motors supported
• Advanced sinusoidal field oriented control (FOC)
• True current control protects equipment and boosts responsiveness
• Reliability guaranteed by wide safety margins and quality components
• Electrical & mechanical braking of motor in faults & disable
• Fully automatic internal homing controller
• Optimized for CNC and machine automation
• Robust 200V 60A MOSFET power stage
• Panel installation, 19" rack compatible.
• Regenerative brake resistor output
• Hard to kill: short circuit, over current, over temperature, I²t, over voltage and under voltage protections
• Advanced positioning with acceleration limit and smoothing

DualDC mode

A special feature of VSD-E/XE is that it can control two independent brush DC servo motors on single drive. This mode is achieved by downloading a freely available DualDC firmware to the drive. DualDC mode has several restrictions compared to single axis mode due to hardware limitations.

Purchasing

Before purchase

Before purchasing the drive, it is suggested to:

• Ensure product suitability for your needs:
  • See VSD-E/XE PDF manual chapter 13 for supported motor and feedback device types
  • Check if a compatible reference signal is available from your controller
  • Read through the drive manual to understand the product and requirements better
• Make clear what additional items will be needed, such as power supplies and possibly interface electronics
• If unsure about suitability, please send inquiry to Granite Devices support to be sure

How to purchase

VSD-E base price in single quantities is €199 and VSD-XE €243 excluding VAT. Both models are currently under active production and can be purchased from GD Web shop or from any GD distributor.
