If neither of the digital inputs is programmed for left or right enable, then the actuation of a fixed frequency or jog frequency will
enable the frequency inverter. The rotation field direction depends on the sign of the setpoint.

Also effective for bus control (RS232, RS485, CANbus, CANopen, DeviceNet, Profibus, InterBus, AS-Interface)

{ 0.10 }
Setting of the stop time for the fast stop function which can be triggered either via a digital input,
the bus control, the keyboard or automatically in case of a fault.
Emergency stop time is the time for the linear frequency decrease from the set maximum
frequency (P105) to 0Hz. If an actual setpoint <100% is being used, the emergency stop time is
reduced correspondingly.

In the standard setting (P428 =0  Off) the inverter requires a flank to enable (signal change
from "low high") at the relevant digital input.
In the setting On  1 the FI reacts to a High level. This function is only possible if the FI is
controlled using the digital inputs. (see P509=0/1)
In certain cases, the FI must start up directly when the mains are switched on. For this P428 = 1
 On can be set. If the enable signal is permanently switched on, or equipped with a cable
jumper, the FI starts up immediately.
NOTE: (P428) not "ON" if (P506) = 6, Danger! (See note on (P506))
NOTE: The "Automatic Start" function can only be used if a digital input of the frequency
inverter (DIN
1 … DIN 4) is parameterised to the function "Enable Right" or "Enable
Left" and this input is permanently set to "High". The digital inputs of the technology
units (e.g.:SK CU4 - IOE) do not support this "Automatic Start" function.
NOTE: The "Automatic Start" function can only be activated if the frequency inverter has
been parameterised to local control ((P509) setting { 0 } or { 1} ).
