Set V/F pattern
(3) Base frequency voltage setting (Pr. 19)
⋅ Use Pr. 19 Base frequency voltage to set the base voltage (e.g. rated motor voltage).
⋅ If the setting is less than the power supply voltage, the maximum output voltage of the inverter is as set in Pr. 19.
⋅ Pr. 19 can be utilized in the following cases.
(a) When regeneration frequency is high (e.g. continuous regeneration)
During regeneration, the output voltage becomes higher than the reference and may cause an overcurrent trip
(E.OC ) due to an increased motor current.
(b) When power supply voltage variation is large
When the power supply voltage exceeds the rated voltage of the motor, speed variation or motor overheat may
be caused by excessive torque or increased motor current.
(c) When you want to expand constant-power characteristic range
To expand the constant-power range at the base frequency or less, set a value greater than the power supply
voltage to Pr. 19.
⋅ Set parameters as below when running the vector control dedicated motor (SF-V5RU, SF-VR) under V/F control.
Motor Type
SF-V5RU-3.7kW or less
SF-V5RU-5.5kW or more
SF-V5RUH-3.7kW or less
SF-V5RUH-5.5kW or more
SF-VR
SF-VRH
REMARKS
When operation is discontinued under vector control due to failure of an encoder, etc., setting "9999" in Pr. 80 Motor capacity or Pr. 81
Number of motor poles enables V/F control operation.
CAUTION
⋅ When advanced magnetic flux vector control mode, real sensorless vector control or vector control is selected, Pr. 3, Pr. 47, Pr.
113 and Pr. 19 are made invalid and Pr. 83 and Pr. 84 are made valid.
Note that Pr. 3 or Pr. 47 and Pr. 113 values are made valid as inflection points of S-pattern when Pr. 29 Acceleration/deceleration
pattern selection = "1" (S-pattern acceleration/deceleration A).
⋅ When Pr. 71 Applied motor is set to "2" (adjustable 5 points V/F characteristic), the Pr. 47 and Pr. 113 setting becomes invalid. In
addition, you cannot set "8888" or "9999" in Pr. 19.
⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Make
setting after confirming the function of each terminal.
