The functions of the clearly predefined inputs depend on the type of control (bus system
or IO). They are specified in the following table.
Predefined function Control via ”Fluxx” or via digital IOs Control via CAN bus Control via Profibus
8 BCD-coded inputs (type
930MA140400 only)
The selection of the travel data set is effected
via 8 inputs. For this purpose, the lower 4 inputs
are used in a binary coded manner for the
definition of the first decimal place (0…9), and
the upper four inputs are used in a binary coded
way for the second decimal place (0, 10, 20, …,
90). The travel data set thus selected afterwards
can be started by activating the ”Start” input.
No function No function
Start When the input is activated, the travel data set
that is currently selected via the binary coded
inputs of the application box (IP54 box: selected
travel data set = 0) is started. After the start,
also subsequent travel data sets (see next travel
data set on the ”Travel data sets” tab) are
effected.
For starting a travel data set, the edge of the
”Start” input is evaluated.
The ”Start” function can only be used if the
operating modes ”Online level 1” or ”Offline
(Fluxx)” are set.
No function No function
Stop In case of an active input signal, the travel
program is stopped irrespectively of the status
of the ”Start” input.
After deactivation of the ”Stop” input, the
selected travel program can be restarted by
activating the ”Start” input.
The ”Stop” function can only be used if the
operating modes ”Online level 1” or ”Offline
(Fluxx)” are set.
No function No function
Limit switch, left In case of the reference type ”Limit switch, left”, the digital input is evaluated as a reference. When a
reference run is effected and the limit switch is reached, the home position is set in consideration of
the settings carried out on the ”Reference” tab.
Furthermore, a quick stop is actuated during operation if the limit switch is reached.
Limit switch, right In case of the reference type ”Limit switch, right”, the digital input is evaluated as a reference. When a
reference run is effected and the limit switch is reached, the home position is set in consideration of
the settings carried out on the ”Reference” tab.
Furthermore, a quick stop is actuated during operation if the limit switch is reached.
Quick stop If the input is activated, the motor is braked to the speed 0 at maximum permissible torque.
Additionally, the mechanical holding brake engages if the input is activated. Afterwards, the output
stage of the inverter is switched off, and the ”Quick stop” fault is output. Then an actively applied
torque no longer is available on the motor shaft.
After deactivation of the input, the drive can be restarted. For this purpose, an acknowledgement of
the fault is required for an operation via bus systems.
