Cost-Efficient Dual-Channel Stepper Motor driver on FMC standard

The FMC-MOTDRV22 is a cost-efficient two-channel stepper motor driver series compliant with the ANSI/VITA 57.1 specifications.

Each channel can provide up to 12 V/1.8 A and 24 V/1.8 A per coil for bipolar stepper motors depending on the model. The chopper slope is programmable within three different modes.

Each driver provides a motor load detection without external sensors and a load dependent current control. The board also offers diagnostics and protection against overcurrent, short-to-ground, undervoltage and overtemperature.

These FPGA Mezzanine Card boards are available in three different versions:


These models differ from the voltage rating (12 V or 24 V) and the available power since two of them have an additional connector for external power.

The dedicated cablings are also commercially available in its standard version of 1 meter (FMC-MOTDRV22-CABLE) and of 20 meters (FMC-MOTDRV22-CABLE2). Please ask for a quotation for non-standard cable lengths.
