8.9.1Parameter Read

ATTENTION:Take caution when Parameter write (H92) is executed. By doing this, parameters in inverter are cleared and parameters in remote keypad are copied to inverter.

	Step 1. Move to H91 code.
	Step 2.	Press Enter (	) key once. 0 will be displayed.
	Step 3.	Press Up ( ) key once. Rd will be displayed.
	Step 4.	Press Enter (	) key twice. Rd will be displayed
	Step 5.	H91 is displayed￿￿when Parameter read is finished. VS1-MD AC Drive User Manual
