Control Fault & Step Out Detect
|
        
Sets operation after the drive detects a CF fault when A1-02 = 4 [Control Method Selection = Advanced Open Loop Vector].

If you enter a Stop command but it cannot stop drive operation, the drive will detect CF.

- CF ALM/Stop
-
The drive stops DC injection braking as specified by the value of b2-03 [DC Inject Braking Time at Start].
Note:
-
When A1-02 = 4, control will not be stable if you do not do Rotational Auto-Tuning. This can cause CF faults if you ramp to stop. If the drive detects CF, do Rotational Auto-Tuning and Line-to-Line Resistance Tuning. Also, do Line-to-Line Resistance Tuning.
-
If you set A1-02 = 4 and set these parameters, the drive can detect CF because it cannot stop the operation in some load conditions. Make sure that you do Rotational Auto-Tuning and Line-to-Line Resistance Tuning correctly and then set L8-20 = 0.
