Configuring
—
When configuring the
252 closed-loop control module,
YOU
must
configuring switches —
for speed measurement so that the actual count is interrogated by the
240. Furthermore,
during initialization the
address and the assigned channel of the 240 must also be specified.
The 240 is configured by calling function block FB 173 in restart organization blocks OB21 and
OB22. In this mode, both channels are configured simultaneously; a second mode on the 240 is
therefore not possible.
