AXIS#.BODE.MODE

Description

AXIS#.BODE.MODE sets the mode of the excitation. The excitation can be set to the modes shown in the table below. AXIS#.BODE.MODE is always set to None when EthernetEthernet is a large, diverse family of frame-based computer networking technologies that operate at many speeds for local area networks (LANs) communication is disconnected. The peak amplitude of the excitation is set by either AXIS#.BODE.IAMP or AXIS#.BODE.VAMP (depending on AXIS#.BODE.INJECTPOINT).

AXIS#.BODE.MODE is subject to a watchdog timer (AXIS#.BODE.MODETIMER) as follows:

If AXIS#.BODE.MODETIMER is 0, then AXIS#.BODE.MODE is not affected.

If AXIS#.BODE.MODETIMER is set to a value greater than 0, then AXIS#.BODE.MODE will be set to 0 (None) after the AXIS#.BODE.MODETIMER time milliseconds.

If AXIS#.BODE.MODE is a nonzero value, and you reset AXIS#.BODE.MODE to another nonzero value, you will reset the watchdog timer. This mechanism is intended to turn off the excitation signal if you lose communication with the drive.

AXIS#.BODE.MODE	Description	Comments
0	None	Turns all excitation off
1	PRB	Uses Pseudo Random Binary (PRB) excitation. PRB is a signal that is always +/- peak amplitude, varying only in phase. PRB excitation results in a flat excitation frequency spectrum. PRB results in a high peak excitation amplitude, which can help minimize friction in a frequency response test. PRB excitation repeats every (2^AXIS#.BODE.PRBDEPTH) / AXIS#.BODE.EXCITEGAP drive samples. This repetition can be used to reveal the effects of friction.
2	Sine	Uses Sine excitation
3	Noise	Uses random noise excitation. Noise is a random number generator that varies between +/- peak amplitude.
4	Offset	Sets a torqueTorque is the tendency of a force to rotate an object about an axis. Just as a force is a push or a pull, a torque can be thought of as a twist offset equal to AXIS#.BODE.IAMP
