Lapp OLFLEX SERVO FD 796 CP Screened Servo Cable

Overview

Lapp OLFLEX SERVO FD 796 CP is a screened servo cable with a PUR outer sheath, built for highly dynamic power chain applications in harsh conditions. Lapp lists it as an extended line performance product for long travel lengths or high acceleration, with UL/CSA AWM and VDE certification. It serves as the connecting cable between a servo controller or frequency converter and a motor, in power chains or moving machine parts, and it is intended for use with servomotor product lines from leading drive manufacturers. A low capacitance design enables longer cable runs between drive and motor, and a tinned copper braid screens the cable against electromagnetic interference.

Seven Star LLC supplies the Lapp OLFLEX SERVO FD 796 CP to industrial customers in Oman and the GCC, with engineering support in Muscat. Automated machinery, packaging lines, pick-and-place equipment, machine tools and cable carrier systems all need motor cables that survive millions of bending cycles without conductor breakage. We can help you select the core configuration and cross section from the Lapp article list and confirm the cable against the drive and motor you use.

Cable Construction and Working Principle

The conductors of the Lapp OLFLEX SERVO FD 796 CP are extra-fine wire strands of bare copper (class 6, to VDE 0295 and IEC 60228). Fine stranding lets each conductor bend repeatedly with low stress, which is the basis of power chain flexibility. The core insulation is polypropylene (PP), and the power cores are black with markings U/L1/C/L+, V/L2 and W/L3/D/L- and a green-yellow protective conductor. Depending on the article, the cable contains power cores alone, power cores with one or two individually screened control core pairs twisted together in short lay lengths, or power cores with a control core triplet.

A non-woven wrapping separates the cores from the screen, and a tinned copper braid forms the overall screen. The outer sheath is orange (RAL 2003) PUR. Polyurethane gives high abrasion and notch resistance and good resistance to many mineral oil based lubricants, diluted acids, aqueous alkaline solutions and other chemical media, which are all common on machine tools and transfer lines. The materials are halogen-free, and the flammability ratings include UL/CSA VW-1 and FT1 and IEC/EN 60332-1-2.

Engineering Design of the Lapp OLFLEX SERVO FD 796 CP

The Lapp OLFLEX SERVO FD 796 CP is rated 600/1000 V (IEC U0/U) for both power and control cores, with UL and CSA ratings of 1000 V. The test voltage is 4 kV core to core and 2 kV core to screen. The temperature range for flexing is minus 40 to plus 90 degrees Celsius (80 degrees Celsius under UL/CSA), and for fixed installation it is minus 50 to plus 90 degrees Celsius. The minimum bending radius when flexing is from 7.5 times the outer diameter for cross sections up to 16 mm2 and from 10 times for 25 mm2 and above, while for fixed installation it is 4 times the outer diameter.

Approvals for the Lapp OLFLEX SERVO FD 796 CP include VDE registration number 8591 (some articles pending), UL AWM Style 20234, cULus AWM I/II A/B 1000 V 80 degrees Celsius FT1, CSA AWM I/II A 1000 V 80 degrees Celsius FT1 and UL file number E63634. For use in power chains Lapp asks installers to follow its assembly guideline, and bending cycle data are published in selection table A2-1 in the appendix of the online catalogue. The Lapp OLFLEX SERVO FD 796 CP range runs from 4 G 1.5 mm2 up to 4 G 50 mm2 as pure power versions and in many combinations with control cores up to 4 G 50 + (2 x 2.5) mm2.

Key Features of the Lapp OLFLEX SERVO FD 796 CP

Lapp lists these benefits for the Lapp OLFLEX SERVO FD 796 CP.

• It allows much faster speeds and accelerations, which increases the economic efficiency of machines.
• It is suitable for use with servomotor product lines from leading drive manufacturers.
• A low capacitance design enables a longer cable connection between the frequency converter and the motor.
• It resists contact with many mineral oil based lubricants, diluted acids, aqueous alkaline solutions and other chemical media.
• A wide temperature range suits harsh climatic environments.
• Copper braiding screens the cable against electromagnetic interference.
• The PUR sheath is abrasion and notch resistant, and the construction is halogen-free.
• It is suitable for indoor and outdoor use, and is UV-resistant.

Industrial Applications

The Lapp OLFLEX SERVO FD 796 CP is used as a connecting cable between servo controller and motor in power chains and moving machine parts. Typical uses are assembly and pick-and-place machinery, machine tools, particularly in wet areas, transfer lines, production lines and all kinds of machines with moving axes. In the Sultanate of Oman it suits automated packaging and bottling lines, workshop machine tools, material handling systems, robotic cells and cable carriers on gantry equipment in industrial estates such as Sohar and Salalah. For fixed runs inside panels and cable trays it can also be used, because the same construction is rated for fixed installation.

Cable selection for the Lapp OLFLEX SERVO FD 796 CP should consider the motor current, the cross section needed for voltage drop and heating, the number of control pairs for encoder or brake signals, the bending radius allowed by the chain and the required travel. Seven Star LLC can help customers map these requirements to the article numbers in the Lapp data, for example article 0027950 for 4 G 1.5 mm2, 0027951 for 4 G 2.5 mm2, 0027952 for 4 G 4 mm2 and 0027953 for 4 G 6 mm2, and to confirm lengths and drum quantities for the Lapp OLFLEX SERVO FD 796 CP.
