Re: CIM Motor Reversing
In particular with an arm, the load on the arm is almost always preferentially in one direction (probably what you are referring to as "back"). All other things being equal or even close, it will take more volt-seconds to raise a load than to lower it. If you need to get it to a certain spot, use an encoder, potentiometer, limit switch, or other sensor to tell when the process is complete.
