High-function General-purpose Inverter RX2 Series User’s Manual
Precautions for Correct Use
• Even the setting of 1000 V for all of the free V/f voltages 1 to 7 will not enable the inverter to
output a voltage that is higher than the input voltage or the motor’s voltage selection.
• Set the characteristics very carefully because inappropriately set characteristics may cause
over current to happen during the acceleration or deceleration and/or may cause machine
vibration.
Adjust automatically so as to achieve the minimum output power of the inverter during constant-speed
operation. Suitable for the load corresponding to the reducing torque characteristics of a fan/pump.
Running with this function needs a setting of 01 for the eco drive enable, 1st-motor [Hb145]. The
response and the accuracy can be adjusted by the eco drive response adjustment, 1st-motor [Hb146].
Precautions for Correct Use
• Because this function is implemented by relatively slow control, a rapid change in load, such
as an impact load, may stall the motor and cause an over current trip
• This function acts when either the V/f control (constant torque characteristics) or the V/f con-
trol (reducing torque characteristics) is selected.
