Second Speed Loop Stabilization Coefficient
Program  Feedback  PG
During closed-loop operation, this parameter sets the response sensitivity of the
ASD when monitoring the output speed for control.
The larger the value entered here, the quicker the response to changes in the
received feedback.
Load Moment of Inertia 2
Program  Feedback  PG
This parameter is used for calculating accel/decel torque when compensating
for load inertia while operating in the Drooping Control mode.
Speed PID Switching Frequency
Program  Feedback  Feedback
While running, this parameter establishes the threshold speed setting that is
used to determine if PID control may engage or remain engaged if active.
V/I Input Bias
Program  Frequency  Speed Reference Setpoints
This parameter is used to fine-tune the bias of the V/I input terminals.
Note: See note on pg. 55 for additional information on the V/I terminal.
This setting may be used to ensure that the zero level of the input source (pot,
pressure transducer, flow meter, etc.) is also the zero level setting of the ASD
system.
This is accomplished by setting the input source to zero and adjusting this
setting to provide an output of zero from the ASD.
V/I Input Gain
Program  Frequency  Speed Reference Setpoints
This parameter is used to fine tune the gain of the V/I input terminals.
Note: See note on pg. 55 for additional information on the V/I terminal.
This setting may be used to ensure that the 100% level of the input source (pot,
pressure transducer, flow meter, etc.) is also the 100% level setting of the ASD
system.
This is accomplished by setting the input source to 100% and adjusting this
setting to provide an output of 100% from the ASD.
