PARAMETER
The terminal 1 (frequency setting auxiliary input)
signal is added to the main speed setting signal of
the terminal 2 or 4.
When an override is selected, the terminal 1 or 4 is
used for the main speed setting and the terminal 2 for
the override signal (50% to 150% at 0 to 5V or 0 to
10V). (When the main speed of the terminal 1 or
terminal 4 is not input, compensation by the terminal
2 is invalid.)
Use [
Pr. 125 ( Pr. 126 ) frequency setting gain ] to change
the maximum output frequency at input of the
maximum output frequency command voltage
(current).
At this time, the command voltage (current) need not
be input.
Also, the acceleration/deceleration time, which is a
slope up/down to the acceleration/deceleration
reference speed, is not affected by the change in [
Pr.
73 ] setting.
When "4" is set in [ Pr. 858 Terminal 4 function
assignment ], [ Pr. 868 Terminal 1 function assignment ], the
setting of terminal 1, terminal 4 is used for stall
prevention operation level setting. When terminal 1
and terminal 4 are used for frequency setting, set "0"
(initial value) in [
Pr. 858 ] and [ Pr. 868 ].
Also when using with FR-A7AZ, terminal 6 is
available. To use terminal 6 for frequency setting, set
[
Pr. 406 = 0]. (Refer to page 43)
