Control locations and control modes

Stand-alone mode

Control location EXT1 is used for the stand-alone mode when the crane motion is
working alone. For more information, see
The homing control mode is used in the stand-alone state. For more information, see
section
A speed-controlled crane is also controlled in control location EXT1.

Master/Follower and Synchro control mode

Control location EXT2 is used for the Master/Follower and Synchro control mode
when the crane motions (for example, hooks) are working together. For the Master-
Follower data transfer, see the figure in section
drives (Only in EXT2
The control location EXT2 Master can be in the speed or torque control mode and
the Followers can be in the speed, torque or Synchro control mode.

Crane macro

This section describes the default control interfaces and signals of the macro and
shows the connection diagrams. You can give all drive commands and reference
settings from the control panel (local control) or an external device (external control).
The LOC/REM key of the panel selects between local and external control.
The drive is speed-controlled as default.
EXT1 is the default external control location of the application program. The
reference signal is connected to analogue input AI1. The Start Fwd and Start Rev
signals are connected to digital inputs DI1 and DI2. By default, the direction is fixed
to REQUEST (with parameter 10.03).
The Slowdown signal, the Fast Stop signal DI5, High-end limit and Low-end limit
signals do not have any default values as they are pointer parameters. You have to
configure these signals.
Two analogue signals (speed and current) and three relay output signals (Brake Lift,
running and inverted fault) are available.
The default signals on the display of the control panel are SPEED, CURRENT and
TORQUE.
