14.4.1 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 the
Operation Mode 630 for the stopping behavior.
14.4.2 3-Wire-Control
In the case of the 3-wire control, the drive is controlled by means of digital pulses.
The drive is prepared for the start via the logic state of the signal
Start 3-Wire Con-
trol
87 and started by a Start Clockwise (Parameter Start Clockwise 68) or a Start
Anti-Clockwise (Parameter
Start Anti-Clockwise 69) pulse. The drive is stopped by
switching the signal
Start 3-Wire Control 87 off.
The control signals for Start Clockwise and Start Anticlockwise are pulses. The func-
tions Start Clockwise and Start Anticlockwise are latching signals if the signal
Start 3-
Wire Control
87 is switched on. The lock is released if the stop signal is switched off.

The drive is started according to the configured starting behavior when the signal
Start 3-Wire-Control 87 is switched on and a positive signal edge for Start Clockwise
or Start Anti-Clockwise is detected.
Once the drive has been started, new edges (1) on the start signals are ignored.
If the start signal is shorter than 32 msec (2) or if both start signals were switched on
within 32 msec (2), the drive will be stopped according to the configured stopping
behavior.
3-wire control is activated via parameter
Local/Remote 412:
