0: 0 V to 10 V/0% to 100% (input impedance: 20 kΩ)

1: -10 V to +10 V/-100% to 100% (input impedance: 20 kΩ)

Current input

I

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

S1-2

V

H3-09

0: 0 V to 10 V/0% to 100% (input impedance: 20 kΩ)

1: -10 V to +10 V/-100% to 100% (input impedance: 20 kΩ)

Current input

3: 0 mA to 20 mA/0% to 100% (input impedance: 250 Ω)

A3

Voltage input

S1-3

V

(Default)

H3-05

0: 0 V to 10 V/0% to 100% (input impedance: 20 kΩ)

1: -10 V to +10 V/-100% to 100% (input impedance: 20 kΩ)

Current input

I

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.

  • Use tweezers or a jig with a tip width of approximately 0.8 mm (0.03 in) to set DIP switches.

  • Set DIP switch S4 to “AI” to use terminal A3 as an analog input (voltage/current) terminal. The default setting for DIP switch S4 is “AI”.
