Setting the deceleration time for the quick stop function which can be triggered via a digital input, bus
control, the keyboard, or automatically when an incident has occurred.
Quick stop time is considered to be the time it takes the FI to reduce the frequency from the maximum
value set (P105) to 0Hz down a linear ramp. If the setpoint effective at the time is <100%, the time of
quick stopping will be shorter by a corresponding amount.
Activation of automatic quick stopping in the event of trouble
0 = OFF: automatic quick stop at fault is deactivated
1 = On mains failure: automatic quick stop at mains failure
2 = On errors: automatic quick stop at fault
3 = Error or mains fail.: automatic quick stop at power failure and fault
With the setting at default (P428 = 0 OFF), the FI will require an edge (change of signal from "low
high") at either of the digital inputs to be enabled.
Set at 1 ON, the FI is started up as soon as a high level is applied. This function is not available
unless the FI is controlled via any of the digital inputs (cf. P509).
In some instances the inverter is required to start up along with the mains power being switched on.
For this purpose P428 is set to 1 ON. If the enable signal is permanently effective or provided with a
jumper, the FI will start up right on being connected to the mains.
