Product Overview

Multiple-Input Multiple-Output Sine VCS

The MIMO Sine Control System provides precise, realtime, multi-channel control and analysis. MIMO Sine supports up to 512 input channels, and up to 8 output channels (shakers). Input channels can be enabled for control, monitoring, and time data recording channels. The recording option records time stream data at the full sample rate on all input channels, regardless of the total channel number. A unique hardware design provides a fast
loop time of less than 10 ms.

Key Features

Step Sine Control

Step Sine uses a sequence of short dwells within a frequency range. The steps are uniformly distributed in a log or linear frequency scale.

  • Step Sine Entry in Run Schedule: user defines the frequency range, step resolution and dwell durations or cycles at each frequency

Continuous Data Recording

During vibration control, all measurement input and drive signals can continuously record to a Spider-NAS or the internal storage residing in each front-end. Users can view and analyze data files with Crystal Instruments Post Analyzer. The variable sampling rate can be enabled to simultaneously record slow-change signals together with high speed vibration data.

Safety Features

  • Abort Sensitivity: a single parameter allows the ensitivity and tolerance of various safety checks to be asily adjusted between customizable lower and upper ounds
  • Shaker Safety Limits: limits for shaker acceleration, velocity, and displacement
  • Open Loop Detection: open loop detection for control signal and each input channel. Detection is based on the pre-defined lowest allowed control level or maximum level change rate.
  • Control Spectral Limits: spectral limits for control signal
  • Max Drive Limit: maximum voltage limit for drive output

Monitoring Through EDM Cloud

All tests in EDM-VCS support status checks through EDM Cloud. With EDM Cloud support, users can set up any VCS test to upload live data or run logs for completed tests to a cloud storage space provided by Crystal Instruments, where data is securely stored in the user’s account.

The EDM Cloud website is located at Users can access EDM Cloud from anywhere in the world to check the status of past and current tests. A secure login flow ensures the status can only be checked by authorized personnel with proper credentials. Multiple logins for accessing the same Cloud account is available.
