Parameter

Description

 

 

 

VECTOR CONTROL

CTRL BASE Speed

Sets the speed in RPM at which the saturation voltage of the control is reached. Above

 

 

this RPM value the control will output constant voltage and variable frequency.

 

Feedback Filter

A larger value provides a more filtered signal but at the cost of reduced bandwidth.

 

Feedback Align

Sets the encoder’s electrical direction of rotation to match that of the motor.

 

Current PROP

Sets the current loop proportional gain.

 

Gain

 

 

Current INT Gain

Sets the current loop integral gain.

 

Speed PROP Gain

Sets the speed (velocity) loop proportional gain.

 

Speed INT Gain

Sets the speed (velocity) loop integral gain.

 

Speed DIFF Gain

Sets the speed (velocity) loop differential gain.

 

Position Gain

Sets the position loop proportional gain.

 

Slip Frequency

Sets the rated slip frequency of the motor.

 

Stator R1

Stator resistance in ohms. If set too high, the motor will tend to stall at zero speed when

 

 

 

reversing or accelerating from low speed. Reducing this value may eliminate the

 

 

problem. When too low, speed regulation may suffer.

 

Stator X1

Stator leakage reactance, in ohms at 60Hz. This parameter has most impact when

 

 

reversing motor rotation at full current limit. If set too low, the decel time will tend to

 

 

increase.

 

Prop Gain #1

The anti–saturation controller’s proportional gain. Leave the gain at the factory setting.

 

 

Do not change this gain unless authorized by Baldor.

 

INT Gain #1

The anti–saturation controller’s integral gain. Leave the gain at the factory setting.

 

 

Do not change this gain unless authorized by Baldor.
