Control and status word, encoder
Telegrams 3 and 4 allow the higher-level control system to directly access the encoder.
Direct access is necessary, if the higher-level control is responsible for the closed-loop
position control for the drive.
If you enable the "Basic positioner" position control in the inverter, then telegrams 3 and 4
cannot be selected, and the inverter handles the encoder control.
