Keypad operation for a static auto-tuning
Keypad display
Description
Tuning time
At PAR_31, set the induction motor auto-tuning
option to “StandStill”.
-
At PAR_41, set auto-tuning mode to “ALL1”.
Auto-tuning begins immediately.
-
Determines motor stator resistance without
rotating the motor.
20–30 sec
Determines motor leakage factor without rotating
the motor.
5–10 sec
Determines motor flux current, rotor time
constant, and stator inductance at the same time
by applying direct current to the motor, without
rotating the motor axis.
15–60 sec
After obtaining the values required, PAR_41 is
automatically changed to “None” to stop auto-
tuning.
If correct values cannot be obtained, and error
message will be displayed. If this is the case,
ensure that all the motor and encoder
parameters were entered correctly, and then
repeat the auto-tuning procedure.
If an error message persists, stop the auto-tuning
procedure and contact LS ELECTRIC technical
service: www.lselectric.co.kr
