BODE.EXCITEGAP

Description

BODE.EXCITEGAP controls how often the excitation is updated. The excitation is updated every n drive samples, 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

The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs COE and CANopen	5013h/0	M_01-00-00-000
