Parameters

Status Internal Parameter, Read-only, Enumerated (signed 16-bit integer)
0 = OK
1 = Fault on A
2 = Fault on B
3 = Fault on A and B
4 = Comms Fault
Pulses Per Revolution Input, Read-write, Analog (signed 16-bit integer)
1 ppr to 30000 ppr
Speed Internal Parameter, Read-only, Analog (signed 16-bit integer)
-32767 RPM to 32767 RPM
Base Speed Input, Read-write, Analog (signed 16-bit integer)
-32767 RPM to 32767 RPM
Output Output, Read-only, Analog (signed 16-bit integer)
-327.67 % to 327.67 %
Comms Errors Internal Parameter, Read-only, Analog (unsigned 16-bit integer)
0 to 65535
Filter Size Internal Parameter, Read-write, Analog (signed 16-bit integer)
1 to 15

This is the sample size for the filter. A larger size provides more filtering and a slower response.
Channel A State Internal Parameter, Read-only, Boolean (signed 16-bit integer)
0 = Low
1 = High
Channel B State Internal Parameter, Read-only, Boolean (signed 16-bit integer)
0 = Low
1 = High
Direction Output, Read-only, Boolean (signed 16-bit integer)

This is the instantaneous direction of the encoder signal.
0 = Forward
1 = Reverse
