Preset V/f Patterns
Notes:
*1 The following conditions must be considered when selecting a V/f pattern:
· The voltage and frequency characteristics of the motor.
· The maximum speed of the motor.
*2 Select a high starting torque V/f pattern only under the following conditions:
· The wiring distance is long - 492ft (150m) and above.
· Large voltage drop at start-up.
· AC reactor is connected to the inverter’s input or output.
· A motor rated below the nominal output of the inverter is used.
*3 Voltage in preset patterns is doubled for 460V class inverters. The 575V patterns are 2.5 times as large as the 230V patterns.
