More Information

Overview Manuals Applications Communication Configuration Diagnostics

Features:

  • The modular cabinet drive accepts documented customer and technology units for control expansion.
  • Motor speed and torque are regulated through stored drive parameters and selected control modes.
  • Operating states and stored faults are available through the display or approved parameterization device.
The current order identifies a NORDAC SK 700E size 1 cabinet frequency inverter for a three-phase motor; the complete drive label defines the installed option package.

Its machine function is programmable motor-speed and torque control, with commands delivered through the fitted terminals or optional communication unit.

Before commissioning, match mains class, motor nameplate, braking components, option modules, terminal assignments, and the saved parameter set. Wait for the DC link to discharge after mains isolation.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Controls conveyor drives that require adjustable acceleration, operating speed, and controlled stopping.
  • Regulates pump or fan motors where the load profile is compatible with the configured drive and motor data.
  • Supports legacy machine service after option modules, braking equipment, terminals, and the parameter record are matched.
  • Optional technology units provide the fieldbus interface selected for the installed automation system.
  • Customer units expose the documented digital and analog control terminals used by the machine.
  • The fitted interface module, addressing, baud rate, and command source must be identified before drive exchange.
  • Motor nameplate data, control mode, ramps, limits, and command assignments are held in the inverter parameter set.
  • A complete parameter backup should be captured before removal and restored only after the replacement hardware is matched.
  • The ParameterBox or approved NORD service tools can be used to inspect and transfer documented settings.
  • The display or connected parameterization device provides operating states and stored fault information for troubleshooting.
  • Fault review should distinguish motor, load, braking, supply, temperature, and control-signal causes before hardware replacement.
  • Protective settings must be coordinated with the connected motor, application duty, and installed protective devices.
Description
SK700E-151-340-A is a NORDAC SK 700E cabinet frequency inverter rated for a 1.5 kW motor at 400 V. The complete type plate identifies the supplied size and voltage class.

The drive regulates motor speed and torque in conveyors, pumps, fans, and other industrial machinery. Motor data, ramp behavior, command sources, and protective limits are stored in its parameter set.

Before replacement, identify the fitted option modules, braking hardware, terminal assignments, and communication interface, then preserve the parameter backup. Isolate mains power and allow the DC link to discharge before touching power terminals or internal assemblies.

Technical notes
Disconnect mains power and wait at least five minutes before opening the drive or touching power terminals; a stopped motor is not electrical isolation. Save the parameter set before replacement.

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which stored data must be backed up before removing SK700E-151-340-A?
Back up motor data, control mode, ramps, limits, digital and analog assignments, fieldbus settings, fault history, and option-module parameters.
What installed option hardware must be matched before replacing SK700E-151-340-A?
Identify every installed customer unit, technology unit, braking component, terminal assignment, and fieldbus option before replacement.
Which machinery duties are appropriate for SK700E-151-340-A?
It supports compatible conveyors, pumps, fans, and machinery only after motor load, duty cycle, braking, and cabinet cooling are verified.
How should current supply of SK700E-151-340-A be checked?
Provide full type-plate images, fitted option modules, condition, quantity, destination, delivery date, and the parameter backup if available.
Can an SK 5xxE inverter replace SK700E-151-340-A without engineering changes?
Migration to an SK 5xxE is not automatic; use NORD guidance to compare wiring, options, parameters, enclosure, and application behavior.
Which manuals should accompany an SK700E-151-340-A inquiry?
Use NORD BU0700 for installation and operation and MI0700 for an engineered SK 700E migration review.
