Upper Limit Frequency

Program Fundamental Frequency Settings

This parameter sets the highest frequency that the ASD will accept as a frequency command or frequency setpoint. The ASD may output frequencies higher than the Upper Limit Frequency (but, lower than the Maximum Frequency) when operating in the PID Control mode, Torque Control mode, or the Vector Control modes (sensorless or feedback).

Note: This setting may not be higher than the Maximum Frequency (F011) setting.

Program Fundamental Motor Set #1

Parameter Type — Numerical

The Base Frequency 1 setting is the frequency at which the output voltage of

the ASD reaches its maximum setting. The Base Frequency Voltage 1

 

 

parameter is set at F409.

Minimum — 0.0

 

For proper motor operation, the Base Frequency should be set for the name-

Parameter Type — Selection List

This function establishes the relationship between the output frequency and the

Factory Default — Constant Torque

output voltage.

 

 

Settings:

 

 

0

— Constant Torque

 

 

1

— Voltage Decrease Curve

 

 

2

— Automatic Torque Boost

 

 

3

— Sensorless Vector Control (speed)

 

 

4

— Sensorless Vector Control (Speed/Torque Switching)

 

 

5

— V/f 5-point Curve (Go to F190 to configure the V/f 5-point settings)

 

 

6

— PM Drive (Permanent Magnet)

 

 

7

— PG Feedback Vector Control (Speed)

 

 

8

— PG Feedback Vector Control (Speed/Torque Switching)

 

 

Note: When operating in the Vector Control mode the carrier frequency should be set to 2.2 kHz or above.

The Automatic Torque Boost and the Sensorless Vector Control selections use the motor tuning parameters of the drive to properly configure the ASD for the motor being used. If Load Reactors or Long Lead Filters are used, or if the capacity of the ASD is greater than the motor, manual tuning of the motor parameters may be required for optimum performance.
