The following conditions must be met before an axis is started for the first
time.
The module is parameterized (SF LED is off).
S
The actual value for the axis to be started has been set.
S
A setpoint was written for the axis to be started.
S
To start the axis, write the start/stop block to address
"module start address + 2."
Note
Before an axis can be started again, it must be stopped with a stop command.
Table 8-5 shows the contents of the start/stop block. The required assign-
ment of the coordination byte is entered in the structure as an initial value.
For a description of the bit assignment of the coordination byte, see chapter
4.3.1.
The write- - access of the start/stop block must be programmed as a word- -
access.
