PowerFlex 700s PID in the inverter

I have a 3-phase motor, with the following parameters: voltage is 200VAC norms, current for 2A, the frequency is 50Hz norms, norms speed is 120 rpm, it is the engine with reduction gear the gear ratio is 1:15, to speed feedback to the controller is set compactlogix L32E, via DeviceNet network, you can help me how to equivalent values ​​of the inverter (internal value) in real value. with datalink 32 bit real, and how to use PID control in inverter to stabilize the motor speedHoàn tác chỉnh sửa.
