17 Motion-control-interface for Profibus connection
The motion control interface is the interface between the communication system and
the motion control system. With factory setting the motion control interface is co
nected to the CANopen
®
system. This connection can be changed to the Profibus sy
As with CANopen
®
parameter Local/Remote 412 MUST be set to “1” = “control via
state machine”.
The motion control functions are available in configuration x40 only.
This setting is necessary to control the inverter and motion control functions with the
help of Control word (located in PZD1-OUT) and Status word (located in PZD1-
IN).
The functions and bit definitions are identical to the descriptions of CANopen
®
With Profibus the mode of operation “interpolated position mode” can NOT be used.
In motion control configurations Profibus objects PZD2-
OUT (reference speed) and
PZD2-IN (actual speed) have no function.
MCI: motion control interface,
MPG: motion profile generator (trajectory generator),
P: parameter,
S: source,
rpm: revolution per minute
Only the grey marked parameters are necessary for controlling the motion control system by
Profibus.
Input parameters P xxxx must be connected to Profibus OUT sources. These input
parameters are direct accessible with parameter Control Level 28 set to 3.
Output sources Q xxx must be connected to Profibus IN parameters (PZD-IN ob-
jects).
