- Control Interfaces: Analog 0–10V / 4–20mA, digital I/O, relay outputs
- Braking Resistors: Compatible with Nord external braking resistors (SK BRW series)
- Software: NORDAC ACCESS (parameter backup, diagnostics, firmware update)
- PLC Integration: Siemens S7, Beckhoff TwinCAT, Mitsubishi MELSEC via fieldbus
Selection Guide
Use the following criteria to confirm the SK700E-112-340-A-GBB-EL is the correct drive for your application:
- Motor Power: Confirm motor nameplate rating ≤ 11 kW
- Supply Voltage: Verify 3-phase 340 V AC supply (suitable for 380V systems with ±10% tolerance)
- Fieldbus Requirement: GBB suffix confirms integrated bus — specify your protocol when ordering
- Braking Duty: EL suffix = built-in braking transistor; add external resistor for high-inertia loads
- Enclosure: IP55 standard; confirm suitability for your installation environment
- Ambient Temperature: Operating range 0°C to +40°C (derate above 40°C)

Replacement & Compatibility FAQ
Q: Can I replace SK700E-112-340-A-GBB-EL with SK750E series?
A: Yes, the SK 750E is the successor series. Mounting dimensions are compatible but parameter migration via NORDAC ACCESS is required. Contact us for a migration checklist.
Q: Is the GBB fieldbus module removable or integrated?
A: The GBB suffix indicates an integrated fieldbus interface. It is not a removable module — the bus interface is built into the drive’s control board.
Q: What does the EL suffix mean?
A: EL indicates a built-in braking transistor. You still need to connect an external braking resistor for dynamic braking; the transistor is internal but the resistor is external.
Q: Do you supply new or refurbished units?
A: We supply both. All units — new or refurbished — pass our 4-step inspection. Condition is clearly stated on the quotation and invoice.
Q: Can you supply the matching Nord gearmotor?
A: Yes. We stock a wide range of Nord SK series gearmotors. Provide your torque and speed requirements and we will recommend a matched drive-motor set.
