Starting frequency converter and adapting control parameters

Introduction
The frequency converter ABB model ACS380 controls the
retractor motor. In order to ensure correct speed and
movement, the controller will set the default control parameters.
These parameters can be adapted to the conditions at the
installation site if necessary. Two menus on the HMI include the
parameters possible to change. The frequency converter
controls the power for the retractor motor based on direct
motor reading and a position encoder inside the motor.
The above menu gives access to position control and position
information.
The position and control of the motor is based on a zero-
calibration position on the retractor S0 and the integrated
position encoder inside the motor. The length of the probe and
the retractor are used to define the various positions needed in
order for the probe to enter the kiln in the most favourable way.
By selecting the Encoder Menu button, a window will pop-up
with a warning, because the override functions available in this
section change the factory configuration of the drive.
To reset the encoder zero-calibration point S0 the probe must
be moved in manual mode to the "correct" S0 position, which is
located 200 mm from the mechanical stop as seen in the
illustration (red arrow).
The frequency converter provides readings of the motor
performance. These data are used to protect the motor from
overloading and to secure that the probe does not get stuck
inside the kiln by excessive incrustations or build-up of material.
The above menu gives access to motor performance data and
overload conditions. Various override functions are available for
users with the right access level. Motor status and frequency
drive error messages can be read.
Refer to the ACS380 manual for further information on
operating the frequency converter.
