The TWI tab
This mode displays in realtime the angle value, Multiturn register value, AGC value and the UVW signal status.
Figure 4: TWI tab, allows access to the AS5132 registers from the serial bus
Value is the Angle[8:0] from the RD_ANGLE (Read Angle) serial command. This value is continuously updated.
The Zero Position value represents the Zero Position register. By clicking on the Set button, the actual angle
"Value" is written into the Zero Position register. Clicking on Reset writes the value 0 to the Zero Position register.
The Multiturn Counter field is the Multiturn-counter[8:0] register value from the READ_MT_COUNTER serial
command. The Multiturn counter register can be set to a specific value by entering the turn number and clicking on
Set. The counter can be reseted to 0 (default value) by clicking on Reset
The AGC value is continuously read from the RD_ANGLE serial command.
The range lamp can be set by two thresholds (Green Orange and Orange Red) which are determined by the
user. Those thresholds have no influence on the AS5132, it is a visual representation only.
The Read Interval can be modified from 10 ms (fastest) to 1 s (slowest).
The BLDC Commuting Signals sub-window is a realtime representation of the commutation signal status on the
AS5132 UVW outputs. For changing the number of pole pairs, see chapter Error! Reference source not found..
