That is a standard 10K quantum drive. One thing I should tell you is that it has an absolute encoder so likely a PM AC motor, that goes to an interface board probably in a J box near the motor. That goes to that RC2 adapter board plugged into the 2407MC board. That RC2 board was an afterthought to adapt a 10K drive to work with an absolute encoder, it is a weak point but shielding is critical! The encoder shield goes to ground inside the encoder but the shield terminal on the RC2 board also goes to ground so make sure the shield is not landed at the RC2 or tailed out to ground anywhere, just in and out of the interface card and dead ending at the RC2.
