SAB VFD Combo XLPE Motor Cable Review: Specs, Price and Applications
Updated: 4 days ago
SAB VFD Combo XLPE combines shielded motor-power conductors with an individually shielded auxiliary pair for a brake or temperature sensor. Series 3569 addresses the practical routing problem of bringing power and a compatible auxiliary circuit to the same motor. Its Class K construction is flexible, but SAB explicitly does not recommend it for cable-track service.
Quick Verdict
Consider Combo XLPE when one cable can simplify an otherwise separate motor-power and auxiliary-circuit route. Confirm the pair gauge, insulation, termination and electrical function before ordering. The integrated pair does not establish encoder, Ethernet or continuously moving robot-dress compatibility.

Design and Engineering Assessment
The auxiliary pair is the reason to select this product instead of a basic four-conductor motor cable. It can remove a separate routing task, but the machine still needs the correct circuit architecture. A brake supply and a temperature-sensor input have different current, voltage and interference requirements. Choose the exact ordered pair for the intended function.
An overall shield and an individually shielded pair perform different jobs. The pair shield helps define the local interference boundary around the auxiliary circuit. The overall shield supports the motor-cable installation. Neither makes termination quality irrelevant, and the drain connection must follow the chosen drive and circuit documentation.
The family heading should not be read as permission to apply 1000 V and 105°C under every approval and duty. The specification distinguishes 600 V UL/cUL from 1000 V WTTC/CSA AWM, and distinguishes the static temperature range from the 90°C approval entry. Preserve those separate conditions in the machine specification.
Specify the Actual Auxiliary Circuit
Start with the motor connection diagram and identify whether the extra circuit serves a brake, thermistor or another supported temperature sensor. State the number of conductors, their gauge, voltage and current requirements. Do not select an auxiliary circuit solely because its connector has two spare contacts.
Check the drive-side input or brake output as well as the motor-side circuit. A thermistor connection may need a particular isolation arrangement or external interface. A brake circuit may need suppression and a controlled release sequence. The cable carries the circuit; it does not provide those control functions.
Check Motor-Power and Pair Terminations
Choose power-core size from the actual installation, motor circuit and approved design. Family voltage and insulation statements do not provide one universal ampacity for every gauge, ambient temperature and grouping arrangement. Identify the protective conductor separately from shields and auxiliary drain wires.
Prepare the termination drawing before cutting the ordered length. Show where the overall shield, pair shield, drains and protective conductor connect. Confirm that the connector or gland can accept the actual outside diameter and the selected conductor construction without damaging strands or exposing an excessive unshielded section.
Routing, Bend Radius and Movement
SAB lists a minimum radius of 12 times outside diameter. Use the exact ordered cable diameter and the required installation conditions when laying out entries, service loops and bends. A physically bendable cable is not automatically suitable for repeated carrier travel.
For a moving axis, obtain a cable specifically qualified for the required travel and duty. Combo XLPE is not recommended in track. Its integrated pair does not override that limitation. Replacing two cables with one is useful only when the combined construction fits the actual mechanical routing.
Cable Length and Drive Compatibility
Treat the entire motor lead as part of the drive installation. Confirm permitted lead length, the drive output arrangement and any required filtering against the exact motor and drive documentation. A broad cable-length statement is not an unlimited reflected-wave or leakage-current guarantee.
Keep the auxiliary circuit within its documented electrical limits across the full installed length. Include connections and any junctions in the assessment. Commission the motor and auxiliary function together so a correct motor run does not hide a failed temperature input or incorrect brake sequence.
Selection and Installed Cost
Compare Combo XLPE with a suitable motor cable plus a separate auxiliary cable. Include connectors, glands, routing labor, enclosure entry space and replacement access. A single jacket can simplify installation while making the replacement assembly more specific.
Request the complete part number and auxiliary pair configuration in the quotation. Document the actual supply length and termination scope. Do not treat a price for a short reel or one conductor size as the commercial basis for every Series 3569 assembly.
Applications and Selection
Connecting a selected drive and motor when brake or temperature-sensor wiring is also required in the cable assembly.
For SAB VFD Combo XLPE Motor Cable, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Request a quote for the exact power-core gauge, auxiliary pair configuration, cable length and termination scope. Compare complete installed assemblies, including glands, connectors, shield preparation and auxiliary-circuit wiring.
A shared jacket can reduce routing work, but the useful saving depends on the actual machine layout and service plan. Compare a separate-cable alternative using the same electrical duty, movement requirements and installation scope.
Pros and Cons
Advantages
Combines motor power and a specified auxiliary circuit in one route
Individually shielded pair supplements the overall foil/braid shield
Defined insulation and approval scopes support configuration-based selection
Limitations
Not recommended for cable-track service
Pair presence does not establish encoder or data-network compatibility
Conductor size, termination and drive lead-length limits remain application-specific
Who Should Consider SAB VFD Combo XLPE Motor Cable?
Machine builders who need motor power and a specified auxiliary circuit in one routed cable, with a flexible installation that does not require continuous travel in a cable carrier.
SAB VFD Combo XLPE Motor Cable FAQ
What makes Combo XLPE different from basic motor cable?
It includes an individually shielded auxiliary pair in addition to the motor-power conductors and overall shield.
Can the pair carry a brake or temperature sensor?
That is the stated intended use. Match the exact pair gauge, insulation and circuit requirements to the selected motor and drive.
Is the auxiliary pair an Ethernet or encoder interface?
No such general compatibility is established. Those interfaces require their own documented cable and connection requirements.
Is this a continuous-flex carrier cable?
SAB does not recommend Combo XLPE for application in track. Select a suitably qualified construction for repeated carrier travel.
Do all voltage and temperature figures apply together?
No. Preserve the approval-specific voltage ratings and distinguish the 90°C approval entry from the separate static temperature range.
Does shielding remove the need for correct termination?
No. Follow the selected drive and circuit documentation for shields, drains, protective conductors and connector preparation.
Can motor leads be arbitrarily long?
No unlimited system lead length is established. Confirm the drive and motor limits and any required output filtering for the installed route.
What should the purchase specification include?
Include part number, power and auxiliary conductor sizes, circuit function, length, movement, environment, terminations and the applicable approval requirements.
Prices are indicative and may change. Confirm the final configuration, commercial terms and delivery schedule before ordering.
