Fault occurred
Note) Be attentive to below mention when changing output frequency in using the
external frequency command terminal.
- Voltage command input terminal is set only in factory setting.
- Change setting value of parameter H2.01 from 0 to 1 in using the current
command input terminal.
- In setting the function of contact input, H0.02~H0.05, parameter H2.01
is regardless if voltage current command transfer(14) is set.
