User Manual V1.01 4-7
The actual operating mode can be read at all times from the four status LEDs on the
front of the electronic unit.
READY The system has started correctly
FAULT An error has occurred
STAT A Coding for the actual operating state
STAT B Coding for the actual operating state
The display of the various operating states is shown in the figure on the previous page.
In the state ERROR a blink code of the STAT LEDs tells what the actual error is. The
blink codes are explained in chapter ‘Service’.
4.2.1 Operating state “Setup”
As soon as the electronic unit is powered on it goes to the state SETUP, while the
system is initialized and all parameters are loaded. A check is also done to make sure
that all the software modules needed for the correct operation of the unit have been
loaded.
• WAIT FOR DISABLE: the transition occurs automatically after SETUP.
4.2.2 Operating state “Wait for Disable”
The operating state WAIT FOR DISABLE, in which all actuators are off, prevents the
system from starting uncontrolled upon startup. A change to the state DISABLE occurs
only when the RUN and INIT signals are low (0V). This security feature can be disabled
in the Auto-Start Mode, where the system starts automatically.
• DISABLE: if the INIT and RUN inputs are not active.
• DISABLE: the transition is automatic in the Auto-Start Mode.
• ERROR: the transition occurs unconditionally when an error occurs.
4.2.3 Operating state “Disable”
The actuators remain unpowered in this state. The system to switch to the states RUN or
DRIVE INIT.
• DRIVE INIT: if the INIT input becomes active.
• RUN: if the RUN input becomes active and all the drives are already installed.
• DRIVE INIT: the transition occurs automatically in the Auto-Start Mode.
• ERROR: the transition occurs unconditionally when an error occurs.
4.2.4 Operating state “Drive Init”
This operating state serves the zero-position-initialization of those actuators that don’t
come with an absolute measuring system. The actuators to be initialized are powered
and controlled. The different initialization possibilities will be described in detail in
chapter 4.4.
Before all the motors have initialized a warning is active, that prevents the system from
jumping to the RUN state. The system must go through this state at least once.
