Provide 2 analog frequency input channels between VRF1 and ACM or IRF/VRF2 and ACM.
Applicable analog signals:0---5V;0---10V;4---20mA
Can be used as both frequency setting signal and analog feedback signals.
Function setting:

Cd002 =2: Setting by analog signal input to the VRF1 terminal (0 to 5V);
=3: Setting by analog signal input to the VRF1 terminal (0 to 10V or variable resistor);
=4: Setting by analog signal input to the VRF2 terminal (0 to 5V);
=5: Setting by analog signal input to the VRF2 terminal (0 to 10V or variable resistor);
=6: Setting by analog signal input to the IRF terminal (4 to 20mA);
=7: Setting by the sum of analog signal inputs to the VRF1 and VRF2 terminals (VRF1+VRF2);
=8: Setting by the difference in analog signal inputs to the VRF1 and VRF2 terminals (VRF1-VRF2);
=9: Setting by the difference in analog signal inputs to the VRF2 and VRF1 terminals (VRF2-VRF1);
=10: Setting by the sum of analog signal inputs to the VRF1 and IRF terminals (VRF1+IRF);
=11: Setting by the difference in analog signal inputs to the VRF1 and IRF terminals (VRF1-IRF);
=12: Setting by the difference in analog signal inputs to the IRF and VRF1 terminals (IRF-VRF1);

Bias Frequency(VRF1):Cd054=0---600HZ(at 0V);
Gain Frequency(VRF1):Cd055=0---600HZ(at 5V or 10V);
Bias Frequency(IRF/VRF2):Cd062=0---600HZ(at 0V or 4mA);
Gain Frequency(IRF/VRF2):Cd063=0---600HZ(at 5V or 10A, or 20mA);
Frequency corresponding to actual analog input can be modified through bias frequency and gain frequency.
