  • Smartstage manufactures turntables which come with AC motors, and VFD controls.
  • VFD controls, which offer hundreds of programming possibilities, can be complicated to program.
  • Smartstage’s expertise is not in programming, and we do not represent the manufacturer of the control.
  • Smartstage provides the turntable, with the drive, and VFD control PREPROGRAAMMED to give you the basic functions with respect to start up, top speed, and braking.
  • The manufacturer of the VFD is Sunye, and they do not offer any support.
  • Helpful Youtube links are available below (no association with Smartstage).
  • Programming a VFD is a process for those who either are experienced at it, or are willing to undertake the learning, a lengthy time investment.
  • Another possible option, in your city, is to find a motor/control company that might have an available technician to come to your sight, a cost to you.
  • Smartstage does not program your shows or are responsible in any way to program your shows, nor have in-house, or have access to, anyone that can program a VFD.
  • The VFD CAN be programmed in many ways that could result in damage to your turntable, and to the people using it, please be responsible in this regard.
  • Alteration to the VFD programming as provided by Smartstage will immediately VOID any warranty provided by Smartstage, and not just for the control, but the entire system.
