Cost-Efficient Dual-Channel Stepper Motor Driver Mezzanine Card series
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.
This board is licensed by DESY – Deutsches Elektronen-Synchrotron under agreement LV105.
The FMC-MOTDRV22 device is composed of the following building blocks:
The dedicated cablings are also commercially available in its standard version of 1 meter (CABL-FMT0001), 5 meters (CABL-FMT0005) and of 20 meters (CABL-FMT0002).
