Description
You can select the input specifica-
tions of terminal 2 (0 to 5V, 0 to
10V, 4 to 20mA) and input specifi-
cations of terminal 1 (0 to ±5V,
0 to ±10V).
For the 00170 or more, the input
specifications can be selected
when the voltage/current input
switch is off. Terminal 2 is always
used for current input when the
switch is on, the parameter needs
to be set to current input. Override
and reversible operation can be
selected.
Set the ratio of added compensa-
tion amount when terminal 2 is the
main speed.
Set the ratio of added compensa-
tion amount when terminal 4 is the
main speed.
Set the bias side compensation
value of override function.
Set the gain side compensation
value of override function.
Terminal 4 For the 00170 or
input 0/4 to more, the input
20mA specifications can
be selected when
Terminal 4
the voltage/cur-
input 0 to 5V
rent input switch
is off. Set "0"
Terminal 4
when the switch
input 0 to 10V
is ON.
When the current input drops to or
below 2mA, the LF signal is output
and inverter continues operation at
the frequency (average value) just
before current reaches 2mA.
4mA input is not checked.
