Figure 7-12 Brake Sequence Logic of Running Up
The brake sequence logic of running down is similar as that of running up. The
comfortablility can be adjusted via f3, t3 and t4.
Fb-07: C
urrent abnormity identifying time for disengaging the external brake
If output frequency reached and output current does not reach the disengaging current of
brake, and when the setting time of Fb-07 is up, inverter will trip EXT(External fault).
Please check whether motor is well connected or not.
