Basic functions (Pr. 0 to Pr. 9)
Base frequency, base frequency voltage (Pr. 3, Pr. 19)
Use this parameter for V/F control only.
This parameter matches the inverter outputs (voltage, frequency) to the motor rating.
Base frequency voltage
• Use Pr. 3 to set the base frequency (rated motor frequency).
• Use Pr. 19 to set the base voltage (e.g. rated motor voltage).
The motor whose rated voltage is lower than the power supply voltage of the inverter can be used optimally.
If vector control is disabled due to an encoder fault, setting "20" in Pr. 800 "control system selection" enables operation under
V/F control. (Refer to page 182.)
Motor setting ⇒ Pr. 71 "applied motor", Pr. 450 "second applied motor" (Refer to page 123.)
(Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239
Can be used to change between the predetermined running speeds by switching from one terminal to
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX signals).
Using these parameters with Pr. 1 "maximum speed" and Pr. 2 "minimum speed" allows the setting of up to
Valid in the external operation mode or in the combined operation mode that is made available by setting "3 or
4" in Pr. 79.
Valid when "0" is set in Pr. 59.
Priority: RL > RM > RH
