4.10 Waiting for Stabilization of IEPE Sensor
When using the IEPE sensor, stabilization of response of the IEPE sensor is needed after the
initialization of K2 hardware.
This function allows automatic judgment whether response of the IEPE sensor is stabilized or not.
＜ Outline ＞
When the operation start button is pressed while the IEPE sensor is used, the screen of “Waiting for
stabilization of IEPE” appears. It remains displayed until response of all the IEPE sensors is stabilized.
When response of all the IEPE sensors is stabilized, the screen of waiting for stabilization of IEPE
automatically disappears, and the operation mode is switched to the waiting for excitation start status.
When the stop button is pressed while the screen of “Waiting for stabilization of IEPE” is displayed,
the operation mode is switched to the waiting for excitation start status. In this case, note that some
noises are included in response from the sensor, and thus, correct measurement may not be able to be
done.
＜ Judgment of stabilization ＞
If response of the IEPE sensor remains in the range of ±100 mV for 5 seconds, response is judged
to be stabilized.
＜ Process to execute application program from software ＞
When application programs such as SINE are executed from external software including Scheduler,
the screen of “Waiting for stabilization of IEPE” is not displayed. In this case, unless response of the
IEPE sensor is stabilized within 60 seconds, the initialization is judged to be failure and the test is
aborted.
