I/O-06 ~ I/O-10: Analog Current Input (I) Signal
Adjustment
These parameters are used to adjust the scaling of the
"I" analog input signal. The scaling and slope of the
analog signal is adjusted by setting parameters I/O-07
through I/O-10. A filter time (I/O-06) can also be set
to reduce the affects of noise on the analog signal.
Parameter Factory
Default
Setting Range
I/O-06 10 msec 0 ~ 9999 msec
I/O-07 4 mA
0 ~ 20mA
(or max of I/O-09)
I/O-08 0 Hz 0 ~ Max freq
I/O-09 20 mA 0 ~ 20 mA
I/O-10 60 Hz 0 ~ Max freq
This is the filtering time constant for I signal input.
Increasing this value will reduce the drive's response to
noise. However, increasing this parameter will also
make the drive respond slower to speed changes.
.
This is the minimum current of the ‘I’ input at which
the drive outputs minimum frequency (I/O-08).
This is the drives output minimum frequency (or target
value) when there is minimum current (I/O-07) input
on the ‘I’ terminal.
This is the maximum current of the ‘I’ input at which
the drive outputs maximum frequency (I/O-10).
This is the drives output maximum frequency (or target
value) when there is the maximum current input (I/O-
09) on the ‘I’ terminal.
