9-160
Commissioning step:
Define the positioning input signals:
♦ Control commands
♦ Mode selection
♦ Velocity override
All input signals of the technology can be "wired" flexibly using the
BICO technology, e.g. from PROFIBUS-DP or the converter terminal
strip. A hybrid configuration is also possible, with some signals being
transmitted from the field bus and others from the MASTERDRIVES
terminals.
Define which positioning input signals you need, and specify where
they are transmitted from [809].

All control and checkback signals for positioning are described in
detail in the "Control and checkback signals" chapter of manual
/1/; in the subsequent chapters of the Function Description you
will also find timing charts detailing the control sequences for
each of the modes. Special and exceptional situations are also
described.
If you want to define the control signals using the individual binectors,
which can be selected with U710, (i.e. if U530 = 860 [809.7]), you must
nest the "generation of positioning control signals" block in a sampling
time with U953.32 (recommended value = 4).
The first step is to define which modes you want to activate with
[MODE_IN]. You will find detailed information on the individual modes
in the "Function description" Chapter of the "Motion Control for
MASTERDRIVES MC and SIMATIC M7" manual /1/.
For example, if you only want to perform point-to-point positioning with
incremental encoders, you require at least modes 2 and 3 ("homing"
and "MDI"). In step 2 of application example 2, you will find a
description of a simple method of mode activation via the converter
terminals.
Check that the modes are defined correctly with display parameter
n540.14 [809.8].
Define which positioning control commands you want to use [809] and
where they are to be transmitted from. For example, if you only want to
use the point-to-point positioning (MDI) and homing modes, you only
need to wire the following control commands in the simplest case (see
also application example 2, step 2):
♦ Jog forwards [J_FWD] or
♦ Jog backwards [J_BWD], depending on the homing direction
♦ START [STA]
