BY340 from Motrona is a series of compact synchronous controllers, built into a standard. The controllers have DIN housing and are designed for front panel mounting.

Since most affordable in price, these units are also suitable for use with small machines and limited budgets. BY340 has a full angular and positional control with adjustable gear rations and maximum accuracy by 300 kHz of feedback frequency at a control loop cycle of only 250 µsec. BY340 offers manual and automatic facilities to adjust the phase or relative position
between Master and Slave.

PROFIBUS communication is possible with use of the PB251 gateway. With use of SM300/SM600 brackets, BY340 is also suitable for DIN rail mounting.
