12 Quick Start-up Guide for ACS850 with Standard Control Program
3-wire: Start/Stop commands are determined on the
basis of the two sources selected by parameters
10.02 and 10.03.

In1F In2R: The signal defined in parameter 10.02
starts the drive in the forward direction, and the
signal defined in 10.03 will start the drive in reverse.
In1St In2Dir: The signal defined in parameter 10.01
will start the drive (0 = Stop, 1 = Start). The signal
defined in 10.03 will change the motor direction
(0 = forward, 1 = reverse).
Select the start/stop function and signal sources for
external control location 2 (EXT2).
The selections are as with EXT1 above.
Define the signal source to switch between external
control locations EXT1 and EXT2 (0 = EXT1, 1 =
EXT2).
Select the motor start function.
Automatic is the best all-round setting that also
enables flying start (starting when the motor is
rotating).
Fast involves pre-magnetization of the motor and
should be selected if a high break-away torque is
required.
Const time should be selected if a constant pre-
magnetization time is required. The time is set by
parameter 11.02 DC-magn time.
Select the stop mode.
Coast: The power to the motor is cut off. The motor
is left to coast to a stop.
Ramp: The motor is stopped by decelerating along
the active deceleration ramp (to be defined later).
Select the source of the run enable signal.
If the signal is switched off, the drive will not start, or
coasts to stop if running. 1 = Run enable signal on.
Select the source of the emergency stop OFF3
signal.
If the signal is removed (in other words, changes to
0), the drive will stop along the emergency stop
ramp (defined by parameter 22.12 Em stop time).
