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.
◆
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.
