BONFIGLIOLI ACTIVE Cube ACU 401-23 User Manual

15.4.1 Start command
The parameters Start Clockwise 68 and Start Anticlockwise 69 can be linked to the
available digital control inputs or the internal logic signals. The drive is only acceler-
ated according to the control method after a start command.
The logic functions are used for the specification of the direction of rotation, but also
for using the parameterized Operation mode 620 for the starting behavior and Op-
eration mode 630 for the stopping behavior.
15.4.2 3-wire control
In the case of 3-wire control, the drive is controlled using digital pulses. The drive is
prepared for starting via the logic state of the signal Start 3-wire control 87
and
started by a Start clockwise pulse (Parameter Start clockwise 68) or a Start anti-
clockwise pulse (Parameter
Start anticlockwise 69). By switching off the signal Start
3-wire control
87, the drive is stopped.
The control signals for Start clockwise and Start anticlockwise are pulses. The func-
tions Start clockwise and Start anticlockwise for the drive are latching-
type functions
when signal Start 3-wire control 87
is switched on. Latching is cancelled when the
latching signal is switched off.

The drive is started according to the configured starting behavior if the signal Start 3-
wire control 87
is switched on and a positive signal edge for Start clockwise or Start
anticlockwise is detected.
Once the drive has started, new edges (1) on the start signals will be ignored.
If the start signal is shorter than 32 ms (2) or if both start signals w
ere switched on
within 32 ms (2)
, the drive will be switched off according to the configured stopping
behavior.
3-wire control is activated with parameter Local/Remote 412:
