Orientation from the stop status (V/F control, Advanced magnetic flux vector control)
●
Turning ON the start signal after turning ON the orientation command (X22) will increase the
motor speed to the Pr. 351 "Orientation speed", and then orientation operation will be performed
with the same operation as for "orientation from the running status".
●
Note that the DC injection brake operates without increasing to the orientation speed if the
position signal is within the DC injection brake start position.
