7.2.1.1 Controlword in Prole Position Mode
Table 7.6 shows the structure of the Controlword. Table 7.7 denes the values for bit 4, 5 and 9 of the Controlword. Table 7.8
denes the values for bit 6 and 8 of the Controlword. If no positioning is in progress, the rising edge of bit 4 starts the
positioning of the axis. If positioning is in progress, the values given in Table 7.7 dene the behavior.
