Automatic start after switching on the mains voltage
The automatic start can be activated in 0x2838:002 (P203.02).
Preconditions for the automatic start:
• Flexible I/O configuration is selected: 0x2824 (P200.00) = "Flexible I/O configuration
[0]"
• For the start command, a digital input has been configured. (In case of keypad or
activated network control, an automatic start is not possible.)
The following diagram demonstrates the function:

①
Start at power-up = "Off [0]": After switching on the mains voltage, a renewed start command is required to start the motor.
②
Start at power-up = "On [1]": After switching on the mains voltage, the motor starts automatically if a start command is active.

Setting can only be changed if the inverter is
Behaviour after start command.
After start command, the standard ramps are active.
•
Acceleration time 1 can be set in 0x2917 (P220.00).
•
Deceleration time 1 can be set in 0x2918 (P221.00).
After start command, the "DC braking" function is active for the time
set in 0x2B84:002 (P704.02).

After the start command, the flying restart circuit is active.
The flying restart function makes it possible to restart a coasting
motor during operation without speed feedback. Synchronicity
between the inverter and motor is coordinated so that the transition
to the rotating motor is effected without jerk at the time of
connection.

Starting performance after switching on the mains voltage.
No automatic start after switching on mains voltage. In addition to the
inverter enable, a renewed start command is always required to start
Automatic start of the motor after switching on the mains voltage if
the inverter is enabled and a start command exists.
