Used to define the frequency inverter’s behavior concerning the enable
digital input and to configure the automatic restart function.
Ed9E-r disabled
After being switched on, as well as after a reset, the frequency inverter
will not start if digital input 1 remains closed (the frequency inverter
will need a new start edge). The input must be closed after switching
on, as well as after a reset, in order to start the frequency inverter.
AVto-0 The frequency inverter will start automatically. (The frequency inverter
does not need a start edge; the signal will continue to be applied.)
After being switched on, as well as after a reset, the frequency inverter
will start automatically if digital input 1 is closed.
AVto-1 The frequency inverter will start automatically once.
After a trip, the frequency inverter will make up to five attempts to
restart at 20-second intervals.
The frequency inverter must be de-energized in order to reset the
counter. The number of restart attempts is counted. If the frequency
inverter does not start after the last attempt, it will switch to an error
condition and request the user to reset the error manually.
AVto-2 The frequency inverter will start automatically twice.
AVto-3 The frequency inverter will start automatically three times.
AVto-4 The frequency inverter will start automatically four times.
AVto-5 The frequency inverter will start automatically five times.
