Chapter 4 - Parameter Description [FU1]
41
[Starting DC Injection Braking Operation]
☞ Note: The DC injection braking parameter does not function
when either FU1-12 or FU1-13 is set to “0”.
☞ Note: FU1-12 [Starting DC Injection Braking Voltage] is also
used as the DC Injection Braking Voltage for the multifunction
input when the multifunction input is set to “DC Braking”.
FU1-20: Maximum Frequency
FU1-21: Base Frequency
FU1-22: Starting Frequency
FU1-20 [Maximum Frequency] is the maximum
output frequency of the inverter. Make sure this
maximum frequency does not exceed the rated
speed of motor.
FU1-21 [Base Frequency] is the frequency where
the inverter outputs its rated voltage. It is set upto
Max freq. In case of using a 50Hz motor, set this
to 50Hz.
FU1-22 [Starting Frequency] is the frequency
where the inverter starts to output its voltage.
☞
Note: If the command frequency set point is set lower than the
starting frequency, inverter will not output voltage.
FU1-23: Frequency Limit Selection
FU1-24: Low Limit Frequency
FU1-25: High Limit Frequency
Related Functions: FU2-33 [Rated Current of Motor]
FU2-33: The DC current is limited by this parameter.
