You can control the TDA1085 with a 0-10v signal between 8 (common) and pin 5, one thing to watch for when hooking into the TDA1085 is that the circuit is usually not isolated from the incoming AC supply, if controlling with an analogue signal of 0 to 10v you should use a variable resistance opto isolator, this type is different from the usual opto in that the output offers a resistance that is dependent on the voltage in.
The motor is a Universal type so it can be run in the DC mode, which is what it is running with the TDA1085.
