(4) Frequency resolution
The running frequency of the inverter can be set by
the analog input to the frequency setting input
terminal and the digital input from the operation panel
or parameter unit. The operation panel allows setting
in increments of 0.01Hz up to 100Hz and 0.1Hz at
more than 100Hz, and the parameter unit allows
setting in increments of 0.01Hz from its numeric
keypad.
1) Output frequency resolution
For the output frequency resolution f
OUT
, refer to
the common specifications on page 8.
The output frequency resolution does not change
if the output frequency varies between 0 and
400Hz.
2) Set frequency resolution
The set frequency resolution for the digital input is
determined by the number of digits set by the
operation panel (parameter unit). The set
frequency resolution for the analog input is
determined by the number of analog-to-digital
converter bits.
*1 Since the frequency resolution in the inverter is 0.01Hz,
control cannot be exercised if the resolution setting is
less than 0.01Hz.
*2 do not have terminal 1.
*3 Terminal 6 is available in the with FR-A7AZ.
