Programming and Operation

Overview	The Series 22H Vector Line Regen Control has two control boards installed. The
	“Converter Control Board” is used to rectify and process the incoming power. The
	“Inverter Control Board” provides the inverting and power output functions. Each control
	board has its own J1 terminal strip.
	The Inverter Control Board normally has the keypad connected to it. The J1 terminal strip
	of the Inverter Board provides the user interface for most external connections and
	software parameters. The Inverter Control board is mounted above the Converter
	Control Board.
	The Converter Control Board is programmed at the factory and should not require
	program changes. However, you can change the values of several parameters within the
	firmware (refer to parameters in Appendix B). The J1 terminal strip of the Converter
	Control Board is factory wired for normal operation.
	The keypad must be plugged into the Converter Control Board to change parameter
	values, or access the fault log or the diagnostic information of the Converter Control
	Board. A sheet metal panel separates the two control boards and there is a small access
	hole the the sheet metal panel to attach the keypad to the Converter Control Board. To
	attach the keypad to the Converter control board, use the following procedure:
