Controlling 4 Post Shakers

Shakers

Multi Loop control is typically used for multiple shakers controlling one test item in a single axis – usually the Z (up/down) axis. One VR9500 Revolution controller hardware unit is required for each control loop. Each controller’s drive output drives a separate shaker. 2 loops, 3 loops and 4 loops can be individually controlled. The same profile, or different profiles (of the same type: Random, Shock, or FDR) can be set for each loop. Phase of output drive is synchronized between outputs for Shock and FDR.

Random: Control 2, 3, or 4 output drive loops simultaneously
Transient/Shock: Control 2, 3, or 4 output drive loops simultaneously, output phase is synchronized
FDR: Control 2, 3, or 4 output drive loops simultaneously, output phase is synchronized
Sine: One master controller is used with the drive signal T’d off for the other controllers. Use multiple input accelerometers for Sine averaging, max, min, or extremal control.
