Table 3.26 MFAI Terminals A1 and A2 Signal Settings
Terminal Types of Input Signals Jumper Switch S1
Parameter
No. Signal Level
A1
Voltage input
(Default)
H3-01
0: 0 V to 10 V/0% to 100% (input impedance: 20 kΩ)
Current input
2: 4 mA to 20 mA/0% to 100% (input impedance: 250 Ω)
3: 0 mA to 20 mA/0% to 100% (input impedance: 250 Ω)
A2
Voltage input
H3-09
0: 0 V to 10 V/0% to 100% (input impedance: 20 kΩ)
Current input
(Default)
2: 4 mA to 20 mA/0% to 100% (input impedance: 250 Ω)
3: 0 mA to 20 mA/0% to 100% (input impedance: 250 Ω)
Note:
Set H3-02, H3-10 = 0 [Terminal A1 Function Selection, Terminal A2 Function Selection = Frequency Reference] to set A1 and A2 to
frequency reference. The drive will add the analog input values together to make the frequency reference.
â—† Set Output Signals for MFAO Terminals FM, AM
Set the signal type for terminals AM and FM to voltage or current output. Use jumper switch S5 and H4-07, H4-08
[Terminal FM Signal Level Select, Terminal AM Signal Level Select] to set the signal type.
