Typical applications
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.
| Published maximum | SINAMICS S210 | EL7S / EL7 Series AC Servo Drives |

Kinco's high-performance AC servo drive covering 200 W to 7.5 kW on 220 or 400 V class supplies, with full closed loop, multi-axis synchronisation, vibration suppression and SIL3 STO on selected models.
| Published maximum | SINAMICS S210 | JD Series AC Servo Drives (JD430/620/6… |
|---|---|---|
| Power | 7,000 W | 7,500 W meets or exceeds |
The second-generation Kinco JD drive, paired with SMK motors from 50 W to 7.5 kW. It accepts a very wide range of encoder protocols plus a second encoder, runs CANopen or EtherCAT, and has STO SIL3 / PL e on every model.
| Published maximum | SINAMICS S210 | JD2 Series AC Servo Drives |
|---|---|---|
| Continuous current | — | 26 A |
| Peak current | — | 65 A |
| Power | 7,000 W | 7,500 W meets or exceeds |
| Axes | — | 1 |
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.
