Microstepping drives supplied in Eurocard format

A range of half-stepping and microstepping drives based upon the popular 3U x 160mm Eurocard format are ideally suited to applications where extra smoothness and resolution are required.

SmartDrive, Europe's leading manufacturer of Eurocard format stepper drive systems, is offering a range of half-stepping and microstepping drives based upon the popular 3U x 160mm Eurocard format.

The half-stepping D Series or microstepping DM Series are ideally suited to applications where extra smoothness and resolution are required.

Both ranges utilise top-quality MOSFET technology coupled with high-efficiency heatsinking to provide continuous motor winding currents of up to 16.5A within a 9HP (46mm) module width.

The drives include a feature known as comprehensive dynamic protection (CDP), which reacts within 5 æs to protect against motor winding faults, including short-circuit to winding, short-circuit to ground and low inductance.

In addition, there is protection against irregular motor supply voltage, low logic supply and over-temperature conditions.

Conservatively rated components are combined with thorough production testing of all units under simulated fault conditions and for correct thermal performance.

This ensures that each drive provides a long life of trouble-free operation, even during adverse operating conditions.

The D Series offers full or half-step operation, while the DM Series offers advanced microstepping performance with resolutions from 400 to 51,200 steps per revolution using both binary and decimal setting.

Winding current on both drives can be adjusted from 0.5 to 16.5 A by a DIP (D Series) or rotary Hex (DM Series) switch or a resistor on the backplane.

A boost input can be used to increase current output by 30%.

Both drives share a common pinout, and can be freely interchanged subject to module width.
