Set maximumexternal voltage reference on Terminal 53 at 10 V.(This sets the maximum input signal at 10 V.)Q3-21130BT765.106-11 Terminal 53 HighVoltage10.00 V0.00AAnalog ReferenceIllustration 5.5 Analog Reference 6-11 Terminal 53 High Voltage6. 6-14 Terminal 53 Low Ref./Feedb. Value. Setminimum speed reference on Terminal 53 at 6Hz. (This tells the frequency converter that theminimum voltage received on Terminal 53 (0 V)equals 6 Hz output.)130BT773.11Q3-2114.7 % 0.00 A 1(1)Analog Reference6 - 14 Terminal 53 LowRef./Feedb.
