Issue Number: 7
These parameters show the last 3 trips.
Enables the onboard user program.
Onboard user programming provides a background task that loops continuously and a timed task
that is executed each time at a defined rate. For further information, refer to the Control User Guide.
This parameter indicates the status of the user program in the drive. For further information, refer to
the Control User Guide.
Defines the proportional gain for frequency controller 1.
RFC modes only.
The controller includes a feed forward proportional gain (Kp), a feed forward integral gain (Ki), and a
differential feedback gain (Kd).
Proportional gain (Kp)
If Kp is non-zero and Ki is zero the controller will only have a proportional term, and there must be a
frequency error to produce a torque reference. Therefore as the motor load increases there will be a
difference between the reference and actual frequencies.
Integral gain (Ki)
The integral gain is provided to prevent frequency regulation. The error is accumulated over a period
of time and used to produce the necessary torque reference without any frequency error. Increasing
the integral gain reduces the time taken for the frequency to reach the correct level and increases the
stiffness of the system, i.e. it reduces the positional displacement produced by applying a load torque
to the motor.
