Schneider Altivar 320 wiring / setup help needed

[TadasM]

Gents,


Thank you for your help. Much appreciated!

All is working now as it should be (at leas t for now - until next idea or upgrade for the spindle :) ).

The problem was that I have used Output 4 as FWD (or REV output), the output from this pin cant provide stable voltage (probably due to used analog output as they are kinda combined... (HDBB2 manual). I have connected 12Vout (from output 4) to DI (as rev) and Output 3 to DI1 as FWD directions. Changed VFD settings as per Neale recommendations (FWD priority and Sensorless vector control) and all is working perfectly now :) Spindle can go down to approx 2000 rpm without stalling. Lower than 1000 is making spindle to stall.



So thank You gents again and I really appreciate your time for helping me out on this issue.
