NORDAC SK700E-112-340-A-GBB-EL Replacement for SK700E

Product Overview

NORDAC SK700E-112-340-A-GBB-EL Replacement for SK700E Series: Smooth Transition & Legacy System Compatibility

The NORDAC SK700E-112-340-A-GBB-EL is an 11 kW (15 HP) three-phase variable frequency drive from Nord Drivesystems’ proven SK700E series, designed for demanding industrial motor control applications including conveyor systems, pumps, fans, compressors, and material handling equipment. As aging SK700E units reach end-of-service life or become difficult to source through standard distribution channels, TOPNLMS maintains verified stock of this exact model to support your replacement, upgrade, or emergency retrofit project — with minimal disruption to your production line.

Whether you are migrating from an earlier SK700 or SK500E series drive, replacing a failed unit in an existing control cabinet, or standardizing your spare-parts inventory across multiple production cells, the SK700E-112-340-A-GBB-EL delivers a high degree of backward compatibility in wiring, parameter structure, and physical footprint that simplifies the transition.

Seamless Upgrade Solutions

A successful migration to the SK700E-112-340-A-GBB-EL rarely involves the drive alone. In practice, field engineers replacing an aging Nord drive in a control cabinet will also need to verify or replace several surrounding components to ensure system-level compatibility and long-term reliability.

On the power and wiring side, the existing motor cable terminations and shielded cable routing are typically reusable if the cable cross-section meets the 11 kW current rating. However, if the original installation used an older SK700 series braking resistor or an external Nord BRK braking module, these should be inspected and matched to the SK700E’s braking chopper specifications before commissioning. Input line reactors or EMC filters previously installed upstream of the old drive should also be verified for compatibility with the SK700E’s input impedance requirements.

For fieldbus and communication, the suffix GBB in the part number indicates the integrated PROFIBUS DP option. If your existing PLC — such as a Siemens S7-300 or S7-400 with a CP 342-5 PROFIBUS master module — was already communicating with the predecessor drive via PROFIBUS DP, the GSD file for the SK700E can be imported into STEP 7 or TIA Portal to re-establish the network node with minimal reprogramming. Alternatively, if the site uses CANopen or Modbus RTU, Nord offers corresponding option modules that can be fitted to the SK700E base unit.

On the control and I/O side, the SK700E’s standard terminal strip layout is largely consistent with the SK700 family, meaning that analog setpoint signals (0–10 V or 4–20 mA from a Siemens ET 200S or similar distributed I/O station) and digital run/stop commands can typically be reconnected without rewiring. If the original system used a Nord SK-TU3-PAR parameter module to back up drive parameters, this module can be used to restore the parameter set to the replacement unit, significantly reducing commissioning time on site.

For installations where the SK700E is mounted inside a Nord SK-xU series control cabinet or a custom MCC panel, the physical dimensions of the SK700E-112-340-A-GBB-EL should be confirmed against the available panel space. In most SK700E family installations, the mounting hole pattern and depth are consistent across the 7.5–15 kW power range, allowing a direct mechanical swap. Where cabinet space is constrained, the Nord SK-TU3-IND keypad / operator panel can be relocated to the cabinet door using the standard remote mounting kit, freeing internal space.

If the retrofit also involves upgrading the motor itself — for example, replacing an older IE1-class motor with an IE3 Nord geared motor — the SK700E’s motor data auto-identification routine (motor ID run) should be executed after installation to optimize the drive’s vector control parameters for the new motor characteristics. This is particularly important in applications with high starting torque requirements, such as heavy conveyor drives or agitator systems.

Finally, for sites that require remote monitoring or integration with a SCADA system, the SK700E supports connection to Nord NORDAC LINK or third-party HMI panels via its serial interface, enabling parameter visualization, fault logging, and remote speed reference — all without additional gateway hardware in most standard configurations.

Retrofit Guidance FAQ

Q: Can I reuse the existing motor wiring when replacing my old SK700 with the SK700E-112-340-A-GBB-EL?
A: In most cases, yes. The SK700E uses the same U/V/W output terminal arrangement as the SK700 series. Verify that the existing cable cross-section is rated for the 11 kW / 25 A output current and that the cable shielding is properly grounded at the drive’s PE terminal. No rewiring of the motor end is typically required.

Q: Will my existing PROFIBUS DP network configuration work with the SK700E-112-340-A-GBB-EL (GBB option)?
A: Yes. The GBB suffix confirms the integrated PROFIBUS DP slave interface. Import the SK700E GSD file into your PLC engineering tool (STEP 7, TIA Portal, or equivalent), assign the same node address as the replaced drive, and the network master will recognize the new unit. Parameter mapping between the PLC and the drive’s process data objects (PDOs) should be verified against the SK700E PROFIBUS manual.

Q: How do I transfer parameters from the old drive to the replacement unit?
A: If a Nord SK-TU3-PAR parameter backup module was used with the original drive, insert it into the SK700E-112-340-A-GBB-EL and execute the parameter restore function. If no backup module is available, parameters must be re-entered manually using the SK700E keypad or NORDAC ACCESS PC software. TOPNLMS recommends documenting all parameter values from the old drive before removal.

Q: Does the SK700E-112-340-A-GBB-EL fit in the same panel space as my existing SK700 drive?
A: The SK700E series maintains a consistent mechanical envelope across the 7.5–15 kW power range. In most installations, the mounting footprint is compatible. Confirm the exact dimensions (H × W × D) from the Nord SK700E technical datasheet and compare with your cabinet cutout before ordering if space is critical.

Q: What communication protocols does the SK700E support beyond PROFIBUS DP?
A: The SK700E platform supports CANopen, Modbus RTU, DeviceNet, PROFINET, and EtherCAT via interchangeable option modules. The base unit (without GBB option) includes a standard RS485 serial interface for Modbus RTU communication. Contact TOPNLMS if you require a specific fieldbus variant.

Q: Can the SK700E-112-340-A-GBB-EL control an IE3 motor directly?
A: Yes. The SK700E supports V/f control, sensorless vector control, and closed-loop vector control modes, all compatible with IE3 and IE4 efficiency class motors. Run the motor ID routine after installation to optimize control parameters for the specific motor nameplate data.
