BODE.MODETIMER
Example
Disable BODE.MODETIMER:
-->BODE.MODETIMER //
Set to 0 to disable the watchdog
0
-->BODE.MODE // Observe starting state of the Bode mode
0
-->BODE.MODE 1 // Set Bode mode to PRB
-->BODE.MODE // Observe Bode mode state is the same after 0.5 seconds
1
-->BODE.MODE // Observe Bode mode state is the same after 10 seconds
1
Enable BODE.MODETIMER:
-->BODE.MODETIMER 1000 // Set watchdog to 1 second
-->BODE.MODE 1 // Set Bode mode to PRB
-->BODE.MODE // Observe Bode mode state is the same after 0.5 seconds
1
-->BODE.MODE // Observe Bode mode state has been set to zero after 1.0 seconds
0
Enable and reenable BODE.MODETIMER:
-->BODE.MODETIMER 2500 // Set watchdog to 2.5 seconds
-->BODE.MODE 1 // Set Bode mode to PRB
-->BODE.MODE // Observe Bode mode state is the same after 1.5 seconds
1
-->BODE.MODE 1 // Set Bode mode to PRB, resetting the watchdog timer to the original 2.5 second
value
set above.
-->BODE.MODE // Observe Bode mode state is the same after 3.0 seconds after the original enabling of
BODE.MODE 1
-->BODE.MODE // Observe Bode mode state has been set to zero after 4.0 seconds after the original ena-
bling
of BODE.MODE

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
also results in a high peak excitation amplitude, which can help mini-

mize 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.
