BODE Parameters
BODE.EXCITEGAP
General Information
Type R/W Parameter
Description Controls how often the excitation is updated.
Units Drive samples
Range 1 to 255 drive samples
Default Value 2 drive samples
Data Type N/A
See Also BODE.MODE
Start Version M_01-00-00-000
Fieldbus Index/Subindex Object Start Version
Modbus 38 M_01-03-00-000
Description
BODE.EXCITEGAP controls how often the excitation is updated. The excitation is updated every n drive sam-
ples, where n is BODE.EXCITEGAP. For example, if BODE.EXCITEGAP = 2, then the excitation is updated
every 2/(16,000 Hz) = 1/8,000 Hz = 0.000125 sec. When measuring a system, update the excitation only as
often as the data is recorded.
Example
Set excitation update rate to 8,000 Hz:
-->BODE.EXCITEGAP 2
Set excitation update rate to 4,000 Hz:
-->BODE.EXCITEGAP 4
Get excitation update rate (already set to 8000 Hz):
-->BODE.EXCITEGAP 2
