• Input the speed command in the form of analog voltage.
• The table below shows relationship between the combination of Pr3.00 “Switching between
internal and external speed setup”, Pr3.01 “Speed command direction selection”, Pr3.03
“Speed command input inversion”, analog speed command (SPR) of I/F connector and speed
command sign selection (VC-SIGN) and the motor rotational direction; and the conversion
graph of analog speed command input voltage to the speed command.
