7 Cable Dimensioning

Cables must be routed in compliance with applicable regulations.

7.1 Max. Cable Length

The table below shows maximum permitted cable lengths from the MotorController to actuators, based on cable cross-section.

7.1.1 Formula for Calculating Max. Actuator Cable Length

Max. cable length = (2V voltage drop × copper conductivity (56) × cable cross-section in mm²) / (Max. total actuator current per motor line (I) × 2)

For ±24V standard actuators, the cable cross-section must be at least 0.75 mm². Maximum actuator cable length is measured from the MotorController to the last junction box plus the actuator cable. Permissible voltage drop is 2V. Total actuator current is the sum of all connected actuators' current per motor line. Do not use the PE wire (green/yellow) in the actuator cable.

Example: Max. actuator cable length with 0.75mm² cross-section and 2A current: (2 × 56 × 0.75) / (2 × 2) = 21m.

7.1.2 Max. Cable Length – ±24V Standard Actuators

Actuator cables require a minimum of 2 wires. The PE wire (green/yellow) must not be used.

7.1.3 Max Cable Length – Actuators with MotorLink®

Actuator supply cables require 3 wires: 2 for current carrying, 1 for communication. Using a 5-wire cable is not recommended for parallel-wire configurations.

Diagram Description: Two diagrams illustrate MotorLink® wiring with 3-wire and 5-wire cables, showing '+' and '-' terminals and a 'ML-comm' (MotorLink® communication) terminal. A third diagram shows a 5-core cable connection with specific distance requirements between terminals. A fourth diagram shows L1, L2, L3, N, PE connections for a 3-phase supply, indicating L2 can be used for 'Com'.

For MotorLink® actuators, the maximum total cable length is 50m, irrespective of the formula calculation.

Definition of Total Cable Length: The sum of all cables from the MotorController output to the last actuator, including the actuator's mounted cable.

Diagram Description (Example 1 & 2): Two diagrams illustrate total cable length calculation. Example 1 shows 4 actuators with individual cable lengths (L1-L7) summing up to 50m. Example 2 shows a scenario with a 30m main cable (L1) and four shorter cables (L2-L5) summing to 50m total.
