About the inverter function
[Cd-01] [FM] terminal output form selection is set to
00
• With the "Bias adjustment [Cd-13]" of the "PWM
output," you can bias Point 0 as shown in the below
figure.
(Example) PWM-outputting [dA-01] output frequency
monitor
• I want to perform outputting until a frequency
reaches the maximum frequency when the PWM
output is 100%.
[Cd-13]=0.0%,[Cd-14]=100.0%
(Example) PWM-outputting [dA-02] output current
monitor
• I want to perform outputting until a current reaches
the inverter rated current when the PWM output is
100%.
[Cd-13]=0.0%
、
[Cd-14]=200.0%
• With the "Gain adjustment [Cd-14]" of the "PWM
output," you can change an inclination as shown in
the below figure.
(Example) PWM-outputting [dA-18] output voltage
monitor
• I want to monitor the output voltage.
[Cd-13]=0.0%,[Cd-14]=133.0%
(Example) PWM-outputting [dA-17] output torque
monitor
• I want to apply a PWM output range from 0 to
100% in a torque range from -200 to 200%.
[Cd-12]=01
