Slip Frequency
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.
A larger value provides a more filtered signal but at the cost of reduced bandwidth.
Sets the encoder’s electrical direction of rotation to match that of the motor.
Sets the current loop proportional gain.
Sets the current loop integral gain.
Sets the speed (velocity) loop proportional gain.
Sets the speed (velocity) loop integral gain.
Sets the speed (velocity) loop differential gain.
Sets the position loop proportional gain.
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.
