nInputting Frequency Reference Using Current
When b1-01 is set to 1, you can input the frequency reference from control circuit terminal A2. Input the cur-
rent (4 to 20 mA) in control circuit terminal A2.
When H3-09 (Multi-Function Analog Input Terminal A2 Signal Level Selection) is set to 0 (factory setting)
the input on A2 is added to A1.
Setting Precautions
When inputting a current signal to terminal A2, turn ON pin 2 on DIP switch S1 (factory setting: ON).
•
If using terminal A2 to input the master speed reference and terminal A1 to input the auxiliary frequency
•
reference, set H3-13 (Terminal A1/A2 Switching) to 1.
nSetting Frequency Reference Using Pulse Train Signals
When b1-01 is set to 4, the pulse train input to control circuit terminal RP is used as the frequency reference.
Set H6-01 (PulseTrain Input Function Selection) to 0 (frequency reference), and then set the 100% reference
pulse frequency to H6-02 (Pulse Train Input Scaling).
