Defines the behavior of the drive relating to
the enable digital input and also configures
automatic restart after a failure.
Possible values:
•

: Edge-r: If the enable signal is already
active before the supply voltage is
switched on or before a RESET, the drive
will not start.
A rising edge is required for starting.
•
1
: Auto-0: If the enable signal is already
active before the supply voltage is
switched on or before a RESET, the drive
will start automatically.
•

: Auto-1, …, Auto-5: Following a
trip, the drive will make up to 5 attempts to
restart at intervals according to P6-03.
As long as the supply voltage is not
switched off, the counter content remains.
The number of start attempts is counted. If
the drive fails to start automatically on the
last attempt, it will be switched off with a
fault message, after which a
manual RESET will be required.
Caution:
An automatic restart is possible only when the
control commands are given via terminals
(P1-12 = 0, and P1-12 = 11 when, after a
communication loss, the control is toggled to
the terminals).
