Chapter 1 Outline of the System

1.1 Specifications

1.1.1 Multi-SINE

(1) Control Method ： ①Amplitude Control Portion ：Level control of the swept sine waveform

by using the feed-back method

②Phase Control Portion：Real time waveform control by using the

feedforward method（Cross-talk control

between each axis）

(2) Control Frequency : 0.1～10,000 Hz (However it may be limited by conditions.)

(3) Frequency Resolution : Less than 10-4 of output frequency

(4) Control Dynamic Range : More than 114 dB

(5) Operation Mode

1) Sweep, Spot

2) Control variables : Response signal

(6) Sweep Operation

1) Sweep mode : Linear / Log

2) Sweep type : double / single

3) Direction : forward / backward

4) Manual operation at sweeping excitation pause / sweep pause, reversing of sweep direction,

excitation level change

(7) Test Time : by time / by sweep counts / by excitation times

(8) Input Channel (However it may be limited by conditions.)

1) Number of channels：maximum 64

(Including maximum 32 of ‘Principal Control Channels’)

2) Type of channels : Principal Control channel / Control channel / Monitor channel

(possible to duplicate)

3) Peak Amplitude Estimation Method : Averaged value, rms value, Tracking

4) Control Response Averaging Method : Averaged value control / Maximum value control /

Minimum value control

5) Alarm / Abort function : Level value of Alarm / Abort can be specified for each input

channel.

6) Limit Control Function : the maximum allowance profile data can be specified for each

input channel. When the response exceeding over the specified value is detected

at a concerning channel, the system controls this deviated response not to

exceeding over the level of allowance and continues the testing operation

without stopping. ‘Limit Control Option’ is necessary to use this function as

above.

1 - 2

(9) Output Channel : (However, it may be limited by conditions.)

1) Number of channels : maximum 16

2) Waveform distortion : Less than 0.1 % (1V rms)

(10) Analysis / Display Data

In Level measurement of Multi-SINE, it is assumed that the object signal for measurement is

the sine wave having the same frequency as the rated SINE force. Therefore, the DC signals

out of this assumption can not be measured.

1) The trace of the level for controlled response and response of each input channel

2) The trace of the level for drive

3) Each level data for every moments, accumulated value of the vibration times

4) Control response / Drive transmissibility, Each input channel / Controlled response

transmissibility

5) Distortion and Signal Tolerance of the Response signal to each input channels

6) The data of Transfer function between Principal Control channel and Drive Output

channel,Coherence

(11) Data save : 1) Automatic / Manual

2) Display data save as CSV format

(12) External Contact Function：

1) Input Part : Excitation start, Excitation stop, Pause, Restart, etc

2) Output Part : Waiting for excitation start, In excitation, In pause, Test

completed normally, Test completed in error

(13) Option : Limit Control
