    THK petit-SERVO controller wiring ???

    Hi gang, I bought a THK VLA actuator on ebay that came with a petit-SERVO drive model QT-OP3TH1. I found a datasheet that describes the connectors, but no mention of the pinouts. I was unable to find any more information on the THK technical support site (I did manage to download the control software).

    Anybody have a suggestion on where I might find more detailed information ?

    Thanks.

    A little more info ...

    Understanding the input power connector would be most usefull.
    There are 5 pins labeled ...

    R
    T
    E = Earth/Ground
    P
    N

    I also know that it is single phase 110V AC.
    Any insight into the other inputs would be appreciated.

    Thanks again.

    In the hopes that this may help someone in the future.
    The R and T connections are the 110V AC in.

    The unit powers up now.
    All I have to figure out now is the pinouts for the RS232 interface and the commands to program this puppy.
