● Set the "electromagnetic shorting time at stop" to a non‑zero value to enable the
electromagnetic shorting function. In this case, electromagnetic shorting is
performed with the maximum current limit (relative to the rated peak current of
the motor) defined by F6‑26 after the motor decelerates to the frequency defined
by F6‑11. The electromagnetic shorting function is also limited by the rated peak
current of the AC drive.
● DC braking is not available. Only electromagnetic shorting is available for braking
of synchronous motors.
Figure 3‑47 Timing diagram of start/stop function
DI terminal electromagnetic shorting
The time sequence of the electromagnetic shorting signals of DI terminals for the
"decelerate to stop" or "coast to stop” mode is shown in the following figure.
Note
When electromagnetic shorting is selected for the DI, avoid electromagnetic shorting upon
start/stop.
The priority of electromagnetic shorting/DC braking state is lower than that of the start
signal.
