Motrona BY340/BY641 variable speed drive synchronising units

Click2Contact

The Motrona BY340/BY641 variable speed drive synchronising units are suitable to operate as electronic synchronous controllers with speed-variable drives of any kind and any size, provided they dispose of an analog input to set the speed. The operation is based on a master/slave principle.

The master could basically be any moving part of a machine, provided there is a quadrature incremental encoder signal available from the master motion. The slave would typically be a speed-variable drive like an inverter drive or servo drive or DC drive, but could also be a hydraulic system with a servo valve or similar. In any case, a quadrature feedback signal is also necessary from the slave.

Features include: precision angular synchronisation and speed ratio control; high accuracy due to high feedback frequency range (300 kHz with TTL encoders and 200 kHz with HTL encoders); full remote phase control by index pulse operation, trim functions etc; four programmable alert outputs, over speed, under speed etc; compact unit including operator panel for direct access and RS232 interface for remote access; PROFIBUS DP interface available (option).
