Compact and integrated EtherCAT stepper motor drives

January 2024 Motion Control & Drives

The integrated ASI8100 stepper motor drive from Beckhoff’s range of compact drive technology products up to 48 V DC combines a stepper motor, stepper motor output stage and fieldbus connection in a space-saving design. As an EtherCAT slave, it can be placed directly on the machine without a control cabinet or upstream I/O level, allowing for highly compact, control cabinet-free machines.

The series covers all motion requirements for stepper motors in the power range up to 250 W. Drive monitoring is indicated by integrated status LEDs in this case. With the integrated travel path control, simple function blocks for motion applications are already pre-integrated. The standardised M8 and M12 connectors also provide cost-effective, industrially-compatible connection technology. The two additional I/Os allow drive-related functions such as the detection of end positions, or the latching of positions, to be executed efficiently.

The series starts with 42 mm NEMA 17 drives, available in two stack lengths with a 0,29 or 0,80 Nm holding torque. This is followed by four 56 mm NEMA 23 devices with holding torques of 0,75, 1,4, 2,35, and 2,5 Nm. Pre-assembled cables and infrastructure components such as IP67 distribution box modules are available as accessories.
