7.3 Speed instruction (analog signal) settings from
external devices
You can select from voltage input (0 to 10V, 0 to 5V), and current input (4 to 20mA) for an analog input terminal
(VI). The maximum resolution is 1/1000.

Analog input filter 4 - 1000 ms 64
Note1) When stable operation cannot be attained because of frequency setting circuit noise, increase .
Note2) Semiconductor switch is used to switch between current input and voltage input.
When power supply is off, it is high impedance between VI-CC terminals in spite of current input selecting.
The break detection might operate when current generator (4-20mA) with the break detection function is used.
Please correspond as following to prevent this problem.
1) Solution by sequence
Power supply is switched off inverter and current generator (PLC etc...) at same time with interlock
sequence not to operate break detection function.
2) Solution by external resistor connection
Connect resistor 1/2W-500Ω or 470Ω between VI-CC terminals, and set the following parameter (voltage
input setting).
f109=0 (Voltage input : Default setting)
