ENCODER MATCHING
In PM synchronous motor applications, encoder offset value is the angle difference between
absolute encoder zero point and motor’s magnetic axis. It is crucial to obtain the true offset
value to drive the motor with the right angle and to reach higher efficiency.
Parameter 29 in settings menu is called as “Encoder Match” item and has two values: Passive
and Active. To set this parameter, navigate the menu to parameter 29 and press the ENTER
button for 3 seconds, it is possible to adjust the desired value when
symbol is seen on the
screen.
After setting the value of this parameter as “Active”, press ESC and ENTER buttons
consecutively. Then, in Inspection mode “Match Encoder” warning will appear on LCD
screen.
Encoder matching process will begin if UP button is pressed in Inspection mode. Firstly
“Encoder Matching Started” will be written on screen. After the completion of the process,
“Encoder Matching Completed” will be written on screen.
Note:
During encoder matching process, the belt driven by the motor should be removed if it
is possible. If it is not possible, the door should not be in the limit regions of door opening and
closing, it should be in a point somewhere in the middle.
If encoder matching parameter is set as “Active”, even if door learning process is completed
before, all of the measurements of the door will be reset. Thus, after the completion of
encoder matching process, “Needs to learn” warning will appear on screen again in Inspection
Mode. AT that stage, please follow the instructions that are described in LEARNING THE
DOOR section.
During the production, motor and driver are made as a set and “Encoder Matching”
process is done by Onlab. Therefore, users do not need to perform “Encoder Matching”
process until they change motor and/or driver electronics.
