Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Beckhoff Automation part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
A dual-axis version of the ELD2 for 24-70 VDC systems: 20 or 30 Arms per axis (750 W or 1.2 kW per axis), gantry synchronisation and STO, saving around 30% installed volume versus two single drives.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
