STOPPED 
 
The number of lines per encoder revolution 
Encoder Invert

FALSE 
STOPPED 
Reverses the encoder direction if TRUE.

0:QUADRATURE 
1:CLOCK/DIRECTION 
STOPPED 
 
Normally the encoder will be quadrature.  Exceptionally, eg if a proximity sensor or other pulse train is used, it needs to be clock / 
direction. 
High Input Threshold 
1674 
Same as PNO 1671 
FALSE 
STOPPED 
Changes the threshold level for the encoder pulses between 1.8 V and 6.5 V typical. For encoders powered from 5 V the low theshold 
should be used. For other supply voltages the high threshold will provide greater noise immunity.

RPM 
 
NEVER 
 
The speed measured by the encoder, in revolutions per minute. 
Encoder Count Reset 
1676 
Same as PNO 1671 
FALSE 
ALWAYS 
Resets the encoder count. 
Encoder Count 
1677 
Same as PNO 1675 
Min to Max 
NEVER 
The encoder count is a 32 bit count which will increment and decrement with the encoder pulses, up to (or down to) 2^31.
