The variable frequency drive will not start after being switched on, or
after a reset, if digital input 1 remains closed (the variable frequency
drive 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 variable
frequency drive.
AVto-0 The variable frequency drive will start automatically. (The variable
frequency drive does not need a start edge; the signal will continue to
be applied.)
The variable frequency drive will start automatically after being
switched on, as well as after a reset, if digital input 1 is closed.
AVto-1 The variable frequency drive will start automatically once.
After a trip, the variable frequency drive will make up to five attempts
to restart, with these attempts being made at 20-second intervals. The
variable frequency drive must be de-energized in order to reset the
counter. The number of restart attempts is counted. If the variable
frequency drive 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 variable frequency drive will start automatically twice.
AVto-3 The variable frequency drive will start automatically three times.
AVto-4 The variable frequency drive will start automatically four times.
AVto-5 The variable frequency drive will start automatically five times.
