CSD is the name of a series of ministep bipolar chopper drives, suitable for driving two-phase stepping motors, with four, six or eight terminals.

CSD series drives are realized in 92 x 85 x 23 mm format and are equipped with separated connectors for logic signals and for power connections.

They are designed for easy mounting inside a metal electrical cabinet, by means of spacers or mounting brackets separately supplied by R.T.A. as an option.

The ministep operation, connected with a further electronic resonance damping facility, ensures excellent operating smoothness and low acoustic noise.

Pull-up and pull-down input signals ease interfacing with the most commonly used control systems.

R.T.A. experience, together with a careful design for these specific purposes, has led to a high reliability component, in spite of its very competitive cost.
