5.7.2 Digital I/Os: digital output
The digital output provided can be defined in a free manner with regard to its functions.
The output is configurable as ”Active high” or ”Active low”, the function of the output not
being dependent on the type of control (activation of the servo drive via bus, digital IOs, or
the Fluxx program). For the output, the following selectable functions are provided:
Warning If a warning occurs, the ouput becomes active. Warning signals do not yet result
in a switch-off of the motor, but they can announce operating states which can
become critical.
Example: motor temperature > 130°C
Fault If a fault occurs, the motor is switched off automatically, and in addition the
output is set.
Example: motor temperature > 140°C
Editing data set The output is set as soon as a travel data set is edited, or if a travel data set
currently is in process.
Setpoint reached Here the output is activated from the time where the setpoint specified in the
current travel data set has been reached. The type of the setpoint depends on
the controller type set in the ”Travel data sets” menu, e.g. ”Speed”.
Reference run active Here the output indicates that the motor currently is carrying out a reference
run for protective multiple earthing of the drive.
Drive in standstill As soon as the drive is in standstill, i. e. speed = 0 rpm, the output is activated.
Profibus active In this case, the output activation is effected if the Profibus is activated, e.g. for
communication of the motor as a DP slave with the Profibus master.
System error A system error occurs as soon as the amount of the system deviation is greater
than the value specified in the following error window of the ”Controller”
menu.
Motor deenergised ”Motor deenergised” means that the output stage is disconnected, i. e. a torque
no longer is available on the motor shaft.
Stopover A stopover is characterised by an interrupted travel data set. The command for
a stopover is effected via the digital input.
Single step mode If this configuration is used, an active output signal occurs as soon as the drive
is in single step mode. The single step mode can be activated by selecting
”Single step~On” in the upper menu bar of the user program. The second
possibility to activate single step mode is to tick the ”Single step” check box in
the ”Travel data sets” menu.
Single step pause The pause in single step mode is displayed, which eventually is effected
automatically after completion of a travel data set in single step mode. The
start of the next travel data set is either carried out by a new start command
(Single step~Continue) in the user program, or via a digital input that is
configured by ”Single step”.
Reference set As soon as the reference is set, the activation of the output signal is effected.
This happens after a reference run has been successfully completed. The
reference furthermore is set if no reference run has been set in the ”Reference”
menu.
