(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-output characteristic range
To expand the constant-output 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.
