Hello Emil,
good news, got a manual from HSD, bad news (for you), it is in german.
but anyway, the table for connections on page 30 looks quite good,
so i made a small table for connections:
28 (REF-V) 0-10V analog input -> csmio analog output
29 (GND-A) for analog input
5 (in 5) enable inverter -> csmio digital output
4 (REV) reverse rotation -> csmio digtal output to switch CW/CCW
8 (CM-IN) GND -> 24v GND
1 (FLT-NO) alarm relais -> csmio input inverter ready
2 (FLT-CM) for alarm relaise -> 24V+
6 (EXTFLT) external alarm -> 24V+
22 (IN3) temperature motor (not used) ->24V+
17 (OUT3-CM) -> 24V+
16 (OUT3-NO) -> csmio input output frq. = 0 allow tool change
30 (CM-OUT)

?? -> csmio input frq. reached but it is a open collector
32 (OUT2)

?? is connected to 24V+ does not make sence
so if only OUT2 is connected i should work with this 30/32 connection.
