20.5.2 FSA state
Telegram 100 or more internal status of the driver are controlled with STA state. Figure 5.2 and Table 5.2
show the transition conditions between the FSA states. The states are switched when the master sends a
command following table 5.2 (sets Controlword) after the I/O communication was established. When the
state has transitioned from Not ready to switch on, which is right after the power on, to Operation enabled
with the predetermined procedure, the servo motor becomes ready to operate.
