Incremental Encoder Interface
The DS1103 provides a digital incremental encoder interface with
input channels for seven incremental encoders. The pins which make
up the inputs are called:
n PHI0(1) … PHI0(7), PHI0(1) … PHI0(7)
n PHI90(1) … PHI90(7), PHI90(1) … PHI90(7)
n IDX(1) … IDX(7), IDX(1) … IDX(7)
The incremental encoder interface supports:
n Six digital encoder channels (Ch1 …Ch6) providing single-ended
TTL and differential RS422 signals (programmable by software).
n One analog encoder channel (Ch7) providing 1 V
pp
or 11 μA
pp
differential signals (programmable by software).
Ch6 and Ch7 are based on the TC3005H Tacho Controller.
For detailed information on the TC3005H (for example the
data sheet) contact dSPACE.
