The SSI tab 

By selecting the SSI (serial protocol for AS5040, AS5140, AS5043, AS5045, AS5145, AS5245) tab, the real time information 
of the angular position and the status bits are displayed. See figure 4. 

 

 

 

 

 

Figure 4: SSI tab, shows the SSI bus data of the selected encoder  

 

 

 

Value

 is the Angle data [D11:D0] from the RD_ANGLE (Read Angle) serial command. This value is continuously 

 

updated. 

 

 

 

The 

Zero Pos.

 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 

Magnetic Range Warning

 is continuously read from the RD_ANGLE serial command.  

 

Green lamp: Magnet in range 

 

Orange lamp: Magnet too far or close. MagINC and MagDEC are set. 

 

Red lamp: Magnet too far or close, angle value is invalid and LIN bit is set. 

 

The red lamp is available only when OTP MagCompEN=1, available from the OTP tab. 

 
 

The 

Status bits information

 is taken from the serial stream. 

  
 

The 

Read Interval

 can be modified from 10 ms (fastest) to 1 s (slowest). 

 
 

 

 
 

Magnet angle value 
0 to 359.9° 

Magnet range warning: 
- Green: magnet in Range 
- Orange: magnet too close or too far 
- Red: magnet to close or too far, data 
invalid (if MagCompEN = 1 only) 

Angle register value: 
 
Zero position register access: 
- Button SET: Sets the current angle 
as the 0° angle 
- Button RESET: resets the Zero 
Position register to 0 (default) 

 

Angle value:  
12 bit absolute position: 0 to 4095 
 

Die selection 
(dual die encoders only) 

Status bits information 

Set counter clockwise
 

Display update rate. The readout speed can be 
adjusted from 10ms to 1s
