(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 characteristic range at the base frequency or less, set a value greater than the
power supply voltage to Pr. 19.
CAUTION
⋅ When Pr. 71 Applied motor is set to "2" (adjustable 5 points V/F characteristic), the Pr. 47 setting becomes invalid. In addition, you
cannot set "8888" or "9999" in Pr. 19.
⋅ The signal can be assigned to the input terminal using any of Pr. 178 to Pr. 189 (Input terminal function selection). When terminal
assignment is changed, the other functions may be affected. Please make setting after confirming the function of each terminal.
