Alternatives that meet or exceed these figures
Engineers often come to us with a Siemens 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.
Leadshine's EL7 platform spans 220 VAC drives from 400 W to 2 kW, 400 VAC drives to 7.5 kW and an 11-22 kW high-power range, all with STO and EtherCAT, Modbus/pulse or PROFINET variants.

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.
