6 Parameter Description
Setting
0.0~290.0%(motor rated torque=100%). Used for vector control only.
range
F3-10
Setting
0.0~20.0％(Max. frequency=100％). Used for PG V/F control only.
range
ASR is automatic speed regulator. In vector control ASR outputs the reference torque which is limited by
F3-07~F3-09, while in PG V/F control it outputs the frequency correction value which is limited by
F3-10.
ASR structure(for vector control) is shown below:

ASR structure (for PG V/F control) is as follows:

Note: In PG V/F control, if F3-07 ＝ 0, ASR is limited by F3-10; if F3-07≠0, ASR limit= F3-10×F3-07÷2.5.
F3-04 can be used if different ASR parameters are needed at high-speed and low-speed operation.
Low-speed ASR parameters F3-02 and F3-03 are used at zero speed. High-speed ASR parameters F3-00
and F3-01 are used when the operating frequency is higer than F3-04. When the frequency is between
zero and F3-04, the ASR parameters are smoothly switched from the low-speed ones to high-speed ones
or vice versa, as shown in the following diagram. If only one set of ASR parameters is needed, you can
set F3-04 to 0, i.e. only the high-speed ASR parameters are used.
