Does your controller have enough random resolution?


When testing for product resonances, you need at least three lines of resolution at the half-bandwidth of the resonance. This ensures that you’re exciting the resonance and controlling at the true peak. When testing out to 2,000Hz, you’ll need 8,000 lines and out to 3,000Hz, you’ll need 16,000 lines. With VR controllers, you get:

  • VR9500 and VR105000 controllers have an industry-leading 26,000 lines
  • Improves your low-frequency displacement requirements
  • Fast control loop times maintained
  • Line resolution can be set automatically
