STEPINP MAXFREQ POSCOMP NGUPDT
This register is always set even if the necessary interrupts or errors are not enabled to be displayed.
Data Output Change (Interrupt)
Bit 0, NGUPDT
Output value has changed (message is set over a clock cycle)
Target Position Check (Interrupt)
Bit 1, POSCOMP
Output value matches target position (depth of comparison in accordance with OUTSEL(1:0) definition)
Frequency Error 1 (Error)
Bit 2, MAXFREQ
Input frequency is to high for the set resolution. COUNT(23:0) valid, AX/BX invalid
(monitoring prudent in incremental mode)
Frequency Error 2 (Error)
Bit 3, STEPINP
The input signal phase has turned 90°-270° during a clock cycle, i.e. A4 and B4 have changed simulta-
neously. COUNT(23:0) invalid
(monitoring prudent in parallel-absolute mode)
Undervoltage (Error)
Bit 4, ERRV
Supply voltage too low

TAN D/A converter resolution per segment = 32
Resolution equals 8 times the TAN D/A converter resolution
Output value shifted 1 bit to the right (resolution halved)
Output value shifted 2 bits to the right
Output value shifted 3 bits to the right
Output value increases if cosine before sine (mathematically positive)
Output value decreases if cosine before sine
