The industrial cables you select for variable frequency drives (VFD) need to exhibit both flexibility and the ability to thrive in harsh factory environments. Lapp USA's ÖLFLEX VFD 2XL cable doesn’t just meet these demands—it exceeds them.

Let’s take a closer look at why this cable is the ideal choice for your VFD:

A Robust Cable for Factory Environments

The ÖLFLEX VFD 2XL series is designed for VFD motor connections in both fixed and flexing installations. Able to withstand harsh environments, this cable features an industrial-grade, phthalate-free jacket and resists oil and flames. Thanks to its special XLPE insulation and enhanced thermal properties, it’s suitable for industrial applications up to 2 kV and can withstand 6,000 V—twice the dielectric test voltage.

Expanding its capabilities even further, the ÖLFLEX VFD 2XL cable now features a drain wire—enabling you to protect your cable and equipment from EMI. You can also ground the shield using our SKINTOP MS BRUSH cable gland.

Cable Flexibility Brings Additional Benefits

In addition to being ruggedly constructed, the ÖLFLEX VFD 2XL affords you greater design flexibility. For one, this cable saves space due to the reduced wall thickness of its insulation. Because it doesn’t contain closed raceways, it’s also suitable for open wiring—saving you installation time and costs. And thanks to its low-capacitance design, you can deploy longer cable connections between the frequency converter and motor.

Additional features and benefits include:

  • Wide temperature range: -40° to 90°C (fixed)
  • Minimum bending radii: 15 x OD (occasional flexing), 7.5 x OD (fixed)
  • UL TC-ER approval—no conduit required
  • Multiple certifications—reducing part variety and costs:
    • Class 1 Division 2 per NEC
    • Flexible Motor Supply Cable
    • c(UL) CIC/TC
    • CE (50 V–1 kV)

Motor Duty CyclesWhat Are Motor Duty Cycles?

When selecting a motor, it is important to consider the required duty cycle to ensure the motor can meet the needs of the application.  This blog post and the accompanying light board video will provide a basic introduction to motor duty cycles and a few of the most common types of duty cycles.

The International Electrotechnical Commission (IEC) defines eight classifications for duty cycle which are grouped by continuous, short term, or periodic cycles.  These cycles refer to the sequence and durations in time of all aspects of a typical operation, including starting, running with no load, running with full load, electric braking, and rest.

Motor Feature


Servo MotorsThe ability to size servo motors correctly is imperative for motion-controlled applications, and it can be much more involved than sizing AC induction motors. Acceleration, deceleration, and running torque must still be taken into account, but the servo’s ability to dynamically control the load’s speed and position is also important. During acceleration and deceleration, peak and nominal running torque measurements must be calculated to ensure that the servo motor does not overheat during use. In addition, inertia matching between the motor and load is necessary to ensure optimum response and system performance.
