AKD Benutzerhandbuch | 25.6.7 BODE.MODE
If BODE.MODETIMER is set to a value greater than 0, then BODE.MODE will be set to
l
0 (None) after the BODE.MODETIMER time milliseconds.
If BODE.MODE is a nonzero value, and you reset BODE.MODE to another nonzero
l
value, you will reset the watchdog timer. This mechanism is intended to turn off the exci-
tation signal if you lose communication with the drive.

Example
Set BODE.MODE to PRB:
-->BODE.MODE 1
Get BODE.MODE (already set to PRB):
-->BODE.MODE 1
PRB excitation:
None Turns all excitation off
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^BODE.PRBDEPTH) /
BODE.EXCITEGAP drive samples. This repetition can be used to
reveal the effects of friction.
Sine Uses Sine excitation
Noise Uses random noise excitation. Noise is a random number generator
that varies between +/- peak amplitude.
Offset Sets a torque offset equal to BODE.IAMP
