STK6712BMK4 or SLA7026M or TD62308AP? I dunno....

Mine works as well. But when I hooked two up together I found that it did not. Then I had to optically isolate the step and direction inputs on the circuits to eliminate noise coupling and propagation between them. I also used a schmitt inverter to square up the output of the optocoupler to my sequencer.

Something like this:

Just in case you run into the same sorts of troubles as I did.

hi guys,

when i have read about STK6713BMK4 i found that this IC respond to low level of sequence [ page 1 and 3 in datasheet ].

that means that this ic does not compatible with L297 which give high level of sequence .

for that you need to use STK6713AMK4 which responses with High level ,is it not ?

any suggestions?

hey people.
I have 4 stk6712bmk3 removed from a ricoh sorter-stapler from copier machine FT6655. Great stuff but not working at all.
Some one have made the circuit on eagle?
