The following table shows the conversion table MI-Variable values for this type of feedback with
channels in the UMAC MACRO pack configuration for MACRO IC 1:
Encoder # Which Backplane

Conversion Table MI-
Variable Value
Encoder 1 Acc-24E2x
S1-1,3,4 = ON, OFF, ON
First channel $009000
Encoder 2 Acc-24E2x
S1-1,3,4 = ON, OFF, ON
Second channel $009008
Encoder 3 Acc-24E2x
S1-1,3,4 = ON, OFF, ON
Third channel $009010
Encoder 4 Acc-24E2x
S1-1,3,4 = ON, OFF, ON
Fourth channel $009018
Encoder 5 Acc-24E2x
S1-1,3,4 = OFF, OFF, ON
First channel $009040
Encoder 6 Acc-24E2x
S1-1,3,4 = OFF, OFF, ON
Second channel $009048
Encoder 7 Acc-24E2x
S1-1,3,4 = OFF, OFF, ON
Third channel $009050
Encoder 8 Acc-24E2x
S1-1,3,4 = OFF, OFF, ON
Fourth channel $009058
If not using the 1/T extension of the encoder value, the first hex digit of the MI-Variable value should be
changed from 0 to C. This setting is recommended when using the simulated feedback from a pulse-and-
direction output.
Analog Encoder Feedback
If an analog sine-wave encoder is processed through an Acc-51E high-resolution backplane interpolator
board, the $F0 conversion method is used yielding 4096 states per encoder line. This entry is a three-line
entry.
The following table describes the three-line MI-Variables that need to be configured for the Ubus
Interpolator.
The tables below show the addresses of the quadrature register in the Acc-51E:
