F.4 MacID & Baud rate
MacID and Baud rate are software settable through the standard DeviceNet object.
Default MacID is 63. Supported MacID’s are 0-63.
Default Baud rate is 125. Supported Baud rates are 125, 250 and 500.
F.5 Initial Motion Setup
For the motion to be controlled over the fieldbus the following setup must be done:
On the ‘System Setup’ page, DeviceNet must be selected in the Fieldbus window, or the
parameter FIELDBUS_INTERFACE must be set to 1.
The Fieldbus Scaling Factors (see below) only influence Move 1, so Move 1 must be selected
either through the digital inputs or by setting the parameter GUI_PROFILE_SELECT to 1 or by setting
the bit 0 in the CMND_WORD.
To start the motion, a start signal must be given either through the digital inputs, or by setting
the parameter GUI_START_CMND to 1 or by setting bit 7 in the CMND_WORD .
Note that if the drive is power-cycled, GUI_PROFILE_SELECT, GUI_START_CMND and
CMND_WORD will revert back to 0, so these parameters must be set on every power-up.
Note that CMND_WORD and STATUS_WORD are available on the implicit I/O to ease PLC integration
and minimize service channel (explicit messaging) traffic.
F.6 Fieldbus Scaling Factors
The 5 field bus scaling factors provides an easy, safe, way to command the drive over the fieldbus.
The scaling factors work on the set points of Move 1 as simple gain factors from 0 to 1.
Example:
Move 1 Target position has been set to 100mm.
By varying the FIELDBUS_POS_SCALE_FACTOR between 0 and 1, the drive will position the
actuator to any position between 0 and 100mm.
Note that a set point change only takes place if the START command is 1. Leaving the START
command at 1 turns the drive in to a command follower. The START command can also be controlled
over the fieldbus by writing to the GUI_START_CMND parameter.
