Help with ServoMotor

Hi, ALL; I recovered this motor from a printer, 50M060B, not sure yet if its OK because I don’t know how it works. It has its controller, BD6761FS and a conector with 5 wires:
Black, yellow, blue, white and red and labelled as Vcc, Gnd, /DEC, /ACC and FGS OUT.
/DEC- Decrement Speed, Active LOW
FGS OUT- Control Signal, PWM??
I think /DEC and /ACC could tied to Vcc just to ignore them.
How can I control it with Arduino? Just want to turn it CW andCCW.
Thanks, Alberto
