The BTD1 servo drive is ideal for driving synchronous servomotors (brushless with permanent magnets), equipped with a speed transducer, with voltages up to 260V and maximum currents up to 50A.
The BTD1 has internal analog circuits with IGBT bridge, operation in the 4 quadrants, without zero play.
Settings are made with trimmer and test point; diagnostics via green and red LEDs.
