Modular numerical controller with Low-Jitter synchronisation

摘要

Modular numerical control unit with low-jitter synchronization with at least a main computer (10) and a regulating unit (20, 30). At least a regulating unit has a clock signal extraction unit (23) that derives a synchronizing clock signal (27) from an incoming data stream received by a first receiver unit (21). The signal is forwarded to a transmitter unit (22) thus ensuring the output serial data stream and the input data stream are rigidly phase coupled to each other.
