53-Control Base Frequency - Sets the point on the V/Hz profile where the output voltage becomes a constant value with increasing output frequency. The base frequency point defines the output frequency where the motor goes from constant torque (or variable torque) to constant horsepower operation. The range of adjustment is from 26 to 960 HZ. The factory setting is 60 Hz.
59-Max. Output Volts - Sets the maximum output voltage available to the motor from the control. The maximum output voltage of the inverter can be reduced from the line input voltage to facilitate the use of a motor with an input voltage that is less than the input voltage to the inverter.
Note: In some cases the Max. Output Volts along with the Control Base Frequency adjustment can be manipulated to provide a wider constant torque or wider constant horsepower speed range than is normally available from the motor. The Max Output Volts and Control Base Frequency parameters are normally set to the motors' rated voltage and rated frequency respectively. Caution should be exercised if any other values are set into these parameters. Incorrect values may cause the motor to run at extreme temperatures or fail prematurely.
61-Load Torque Limit FWD - Sets the maximum amount of current that is supplied to the motor under a motoring forward condition before Torque Limiting takes affect. The range of adjustment is 30- 150% of parameter 03-Rated Current. The factory setting is 150%.
