FREEZE is a substate of the DRIVE INIT state that can be reached by means of the
Freeze control signal. In the substate FREEZE all actuators remain powered and
controlled in their respective actual positions. After resetting the Freeze control signal
the system returns to the state DRIVE INIT unchanged.
•
DISABLE: if the INIT input becomes inactive and the RUN input is inactive.
•
RUN: if the RUN input is active and the INIT input becomes inactive (in case the
drives are already installed).
•
RUN: this transition occurs automatically in the Auto-Start Mode as soon as the
initialization is completed.
•
STOP: if the STOP signal becomes active.
•
ERROR: the transition occurs unconditionally when an error occurs.
In the state RUN, the actual working state, the actuators are powered and controlled.
FREEZE is a substate of the RUN state that can be reached by means of the Freeze

returns to the state DRIVE INIT unchanged.
•
DISABLE: if the RUN input becomes inactive and the INIT input is inactive.
•
DRIVE INIT: if the RUN input becomes inactive and INIT is active.
•
STOP: if the STOP signal becomes active.
•
ERROR: the transition occurs unconditionally when an error occurs.
A transition to this state takes place when the Stop signal becomes active, which means
the higher-level control system requested an emergency stop. In this state the actuators
can be either turned off, freezed in the actual position or driven to an emergency stop
position according to their respective configuration.
•
DISABLE: if the inputs RUN, INIT and STOP are inactive.
•
ERROR: the transition occurs unconditionally when an error occurs.
Upon an error a transition to this state takes place unconditionally and from any state the
system might be in at that moment. The motors are not powered and the state can only
be left when the error has been fixed or removed. The actual error is displayed by means
of a blink code and all errors are stored in the electronic unit and can be read by means
of the PC-software.
•
DISABLE: if the error has been removed and the RUN and INIT inputs are
inactive.
