Applications of servo motor cables
Servo motor cables have been developped for the quick connection of computer aided CNC machines as for example CNC mills or drilling machines. They combine a trouble-free combination of current supply and data transmission. Motor connection cables, feedback cables as well as transmission cables belong to the servo motor cables. Further application fields are for example the motor construction for temperature control or industrial fields with intelligent servo drives.
These cables are suitable for the fixed installation and flexible use e.g. in machine and industrial plant construction with average mechanical demand in dry, damp and wet conditions.
Type description | Technical description |
| SL 834 C | Low capacity PUR motor connection cable with overall copper screen 0.6/1 kV |
| SL 835 C | Symmetrical PUR motor connection cable with optimized EMC characteristics 0.6/1 kV |
| SL 851 C - Exploration | PUR motor connection cable with overall copper screen 0.6/1 kV |
Feedback cables are used for controlling motor speed and for giving feedback values. Transmission cables produce transmit control pulses for positioning and procedure characteristics.

Exemplary applications:
Highly flexible, mobile connection cables for e.g. speedo, brake, temperature control in motors, for continuously flexible applications in automation technology, control and production engineering, in cable tracks on wood-working machines, machine and industrial plant construction, even with high mechanical demands and in dry, damp and wet conditions, as well as at low temperatures flexible connection cables e.g. for speedo, brake, temperature control in motors, for continuously flexible applications in automation technology, control and product engineering.
These flexible motor connection cables are used for the power supply of motors. Depending on the construction type supply and control conductors are possible. The cables are suitable for high mechanical demands in dry, damp and wet conditions as well as at low temperatures.
This special multi-conductor cables shall be permitted for used in power, lighting, control and signal circuits in accordance to the National Electrical Code (NEC), NFPA 70 Article 336. In cable trays, in raceways and in outdoor locations supported by a messenger wire in accordance to Underwriters Laboratories Inc. (UL) Standard of Safety UL 1277. For class I division 2 circuits as permitted in NEC article 501.10 (B) and for class II division 2 circuits as permitted in NEC article 502.10 (B). In industrial establishments where the conditions of maintenance and supervision ensure that only qualified persons service the installation, and where the cables are continuously supported and protected against physical demage using mechanical protection, such as struts, angles or channels. These Tray Cables comply with the crush and impact requirements of Type TC and are identified for such use with the ER marking on the jacket. The cables are for use as exposed runs between a cable tray and the utilization device where the cables are continuously supported and protected against physical damage and are secured at intervals not exceeding 1.8 m (6 feet). Grounding for the utilization equipment shall be provided by an equipment grounding conductor within the cables. This Tray Cables shall also be permitted to be used in wet locations and are resistant to moisture and corrosive agents. Cables that are surface marked „oil resistant I” have a jacket that is for exposure to mineral oil at temperature not in excess of 60 °C (140 °F). Marked with „oil resistant II” they have a jacket that is for exposure to mineral oil at temperatures not in excess of 75 °C (167 °F). The Type TC is flame retardant and selfextinguishing. Also sunlight resistant depending on the jacket colour. The cables listed as MTW can be applied in the NFPA 79 machinery area. MTW cables are specified for use acc. to National Electrical Code (NFPA 70) and acc. to the National Fire Protection Association Electrical Standard for industrial machinery (NFPA 79). Wind turbine power and control cables are intended to be installed in cable trays or raceways within a wind turbine generator.

DESINA is an extensive concept for standardizing and distributing fluid and electric installations of machines and plants. A co-operation of machine construction, car manufacturing and supply industries has, furthermore, set up the specification of necessary components.
DESINA applies already existing solutions such as open bus systems, industrial standards for connectors, etc. By standardizing components, interfaces and connecting systems, e.g. an optical fibre copper hybrid cable, most varying systems can be realised on a physical basis.
The following sheath colours are defined as a function code:
