ACC 84 E with UMAC


Recommended Posts

Dear Sir,


We are using ACC 84 E with Turbo UMAC.

In the RACK we have only 2 Accessories 1. ACC 24E2A & ACC 84 E.


Switch Setting on ACC 84 E is Sw1 ON/ 2,3,4, OFF and encoder connected to Channel 1

So the address is $78d00.


We are using 22 Bit SSI GERY code Single turn encoder.

Encoder Voltage is 24 V.

24 V is connected to encoder directly.

24vGnd is connected to GND of encoder & Pin no 5 of D connector.


As per manual we have done the following settings with Technique 3 ( as encoder is Greater than 19 bit)

In encoder conversion table we have done following entries.


Entry 5

Conversion Type -> Parallel position from Y word with no filtering.

Source Add-> $78D00

Witdth in Bits-> 22

Offset - > 0

Normal shifting.


We have assigned $3506 to I103 & I104

As per manual we have set i108=1 and i109=1.


But we are not getting any feedback.


This encoder works with ACC 53E.
