E59
Terminal [C1] function selection (C1 function//V2 function)
Specifies whether terminal [C1] is used with current input +4 to +20 mA/0 to 20 mA or voltage input 0 to +10 V. In
addition, switch SW7 on the interface board must be switched.
E59 data Input form Switch SW7
0 Current input: 4 to 20 mA/0 to 20 mA (C1 function) C1
1 Voltage input: 0 to 10 V (V2 function) V2
When using terminal [C1] as a PTC thermistor input, specify E59 = 0.
For using terminal [C1] for the C1, V2 or PTC function, switching as shown below is necessary.
Terminal [C1] SW3 SW4 E59 H26 C40
For use of C1 function (4 to 20 mA) C1 AI 0 0 0,10
For use of C1 function (0 to 20 mA) C1 AI 0 0 1, 11
For use of V2 function (0 to +10 V) V2 AI 1 0 Does not matter
For use of PTC function C1 PTC Does not matter
1,2 Does not matter
For details about SW3 and SW4, refer to Chapter 2, Section 2.2.8.
Failure to correctly switch as shown above may cause a wrong analog input value, possibly leading to
unexpected operation of the inverter.
Injuries may occur.
Failure may occur.
