Operating Modes

Operating ModeDescription
Polled ModeThe connected host requests the current position value via a remote transmission request telegram.
Cyclic ModeThe encoder sends the current position value cyclically without being prompted by the host.
Sync ModeThe encoder sends the current position value after receiving a sync telegram from the host.
