Description of the ProfiNet interface
Positioning resolution of 1 µm (independent from the real sensor resolution), max. 0x989680 (10.000.000) is
used. The command position is limited by the parameter SYSRANGE.
The command speed is interpreted in percentage of the programmed speed or of the output signal. The
value of 0x3fff corresponds with 100 % speed.
The module is controlled with a
control word
consisting of following bits:
Bit name
Description of the bit
ENABLE
General activation of the axis. Malfunction monitoring and output signal get
activated (in combination with the hardware enable)
START
Start signal for positioning. The actual transmitted command value is taken over
and the output will be controlled relating to the parameterization.
HAND:A
Manual mode. The axis is driven with the preset speed (parameter with the
same name). This mode can only be used when ENABLE is available and the
START comand is not set.
HAND:B
Manual mode, see HAND:A. Two parameters are available for this mode for
example in order to preparameterize manual driving in both directions.
DC_F-POS
Fine positioning function (look at chapter 5.6.6).
DC_ACTIVE
Drift compensation function (look at chapter 5.6.6).
DC_FREEZE
Storing of the drift compensation value as offset for the output.
SC
Synchronous control. In synchronous run the preset values for axis 2 are not
active. The system is driven by the demand values of axis 1.
DIRECT
In direct mode new command positions are taken over directly from the
controller while START signal is available. In normal mode the START signal
has to be reset and set again for getting a new command position into the
module.
PARAMODE
Provides parameterizing the controller via Fieldbus instead of the USB port
(chapter 7.8).
PARAVALID
Transmitting new parameter setting (at rising edge).
LIVEBIT
Here the controller can provide an alternating input signal in order to monitor the
funtioning of the bus connection. It will be returned by the output
“LIVEBIT_OUT”.
Setting of the bits (signal 1) activates the relating function.

Byte notation
Description of the byte
COMMAND POSITION
With the resolution of 1 µm the position which will be driven to after setting
START is preset.
COMMAND SPEED
Sets the maximum possible speed of the axis. 3FFF allows 100%, if the
parameterization provides it. This limitation is also responsible for the manual
mode.
PARAMETER VALUE
New value for a parameter to be changed via the fieldbus (for possible vlaues
and ranges look at chapter 7.8).
PARAMETER ADRESS
Adress of the parameter to be changed (look at chapter 7.8).
