Before executing the operation, to run 4.5.1
Motor & Encoder parameter setting for Auto-
Tuning
is recommended.
4.7.1 Operation command source and speed command setting
1) RUN/STOP command by keypad
2) Operation speed command by keypad
3) Operation speed setting
4.7.2 How to operate magnetic flux estimation operation
Magnetic flux estimation operation in normal condition after checking expected current level
directly rotates the motor, pressing FWD/REV keys.
(1) Check setting for magnetic flux estimation standard level.
(2) If MagDet Err(stimulus estimation error) occurs after RUN command, increase 5% of
magnetic flux estimation standard current (PAR_37) and keep commanding RUN by
keypad until error message is not displayed.
(3) If OC(overcurrent) fault occurs when estimating magnetic flux, decrease 5% of magnetic
flux estimation standard current level(PAR_37) and keep commanding RUN by keypad
(4) If there is no error or fault, please check the status as below.
Caution
Magnetic flux estimation
does not be executed every time and executed by first operation
command after power-on. However, it is executed by initial operation command after reset due
to error or fault.
