9.2.1 Line and DC link identification
Description
Automatic parameter identification is used to determine all the line and DC link parameters,
thereby enabling the controller setting for the Line Module to be optimized.
Note
If the line environment or DC link components are changed, automatic identification should
be repeated with p3410 = 4 (e.g. once the system has been installed or the drive line-up
extended).
The rated current flows during line identification, which can result in a supply-side voltage
dip.
Identification methods
● 0: Identification (Id) off
● 1: Activate identification (Id)
● 2: Set controller setting
● 3: Identify and save controller setting
● 4: Identify and save controller setting with L adaptation
Note
You are advised to use this identification method.
● 5: Reset, save controller setting with L adaptation
For p3410 = 1, 3, 4, 5, alarm A06400 is output to indicate that the specified identification will
take place after the next pulse enable.
p3410 is automatically set to 0 after an identification run has been fully completed.
