4.8.4 Voltage/Current Input Selection(Switches)The analog input terminals 53 and 54 allow setting ofinput signal to voltage (0-10 V) or current (0/4-20 mA).Default parameter settings:• Terminal 53: speed reference signal in open loop(see 16-61 Terminal 53 Switch Setting).• Terminal 54: feedback signal in closed loop (see16-63 Terminal 54 Switch Setting).NOTICEDisconnect power to the frequency converter beforechanging switch positions.1. Remove the local control panel (seeIllustration 4.10).2. Remove any optional equipment covering theswitches.3. Set switches A53 and A54 to select the signaltype.
