Help with encoders for Logosol LS173 drives

[Konstantin]

Hi all.
While attempting to test a LS173 Logosol drive I see that the connector for the encoder has A,B,Z, +5 and GND.
From my junk I have found some encoders but they all lack Z.
I haven't used those encoders yet, I thought I'd better ask before.
Will the LS173 work if it lacks Z from encoder?

What encoder could I use for those drives, assuming its a 250cpr.

It should be OK, it is just that you will lose a home to marker feature, if it is differential encoder input, tie inputs Z high and /Z low.

Al thanks for the quick reply.
I am a bit confused about what to tie up.
Here is the "Encoder and Commutator" pinout of the drive I have:

1 GND
2 ENCODER Z
3 ENCODER A
4 +5V
5 ENCODER B
6 +5V
7 COMMUTATOR S1
8 COMMUTATOR S2
9 COMMUTATOR S3
10 GND

You may not need to pull the single ended Z up if it is not used.
Everything else needs connecting.
Check continuity to see if 4 & 6 are connected, and the GND (commons) are connected internally if so you could just input one supply for both, if separate you could still use a common 5v supply
