If you want to do a simple setup and do not need fast braking then I would suggest the Teco L510 VFD's. Very easy to setup and and less expensive then the WJ200. They have some degree of braking but do not support an external braking resistor needed for fast stops. They also have a detachable keypad if you buy an extension cable. I typically recommend 3 wire control with momentary buttons for stop and run, and a sustained FOR (no connection) or Reverse (connects to the 3rd input). Also Automation Direct has some the GS20 series which are easy to setup. If you have a question on parameters, I can give you a hand.
