About the inverter function
[Cd-01] [FM] terminal output form selection is set to
01
• With the "Bias adjustment [Cd-13]" of the "Digital
frequency output," you can bias Point 0 as shown in
the below figure.
(Example) Digital-frequency-outputting information on
[dA-01] output frequency monitor
• I want to perform outputting so that the maximum
value of the "Digital frequency output" corresponds
to the maximum frequency.
When the maximum frequency is 60 Hz, set
[Cd-02]=60Hz.
[Cd-13]=0.0%
、
[Cd-14]=100.0%
• With the "Gain adjustment [Cd-14]" of the "Digital
frequency output," you can change an inclination as
shown in the below figure.
(Example) Digital-frequency-outputting information on
[dA-02] output current monitor
• I want to perform outputting at a frequency of 1500
Hz when a current corresponding to the inverter
rated current flows.
Set [Cd-02]=3000Hz.
[Cd-13]=0.0%
、
[Cd-14]=100.0%
or
Set [Cd-02]=1500Hz.
[Cd-13]=0.0%
、
[Cd-14]=200.0%
