Application fit

Is Servo Power Cable with Brake Pair right for your machine?

Ideal for vertical Z-axes, gantry loaders and servo actuators that integrate a 24 V DC holding brake or stator thermal sensor inside the motor power plug.

Energy chain / drag chain

Suitable

Individually braided control pairs and Class 6 power cores withstand ≥ 8 million cycles at 7.5 × OD.

VFD inverter to AC motor screened feeder

Suitable

Individual pair screens isolate the 24 V brake coil and KTY/PTC sensor from 1000 V PWM motor switching noise.

Fixed installation

Suitable

UL 1000 V AWM Style 21223 allows single-cable routing from servo drive cabinet to vertical axis motor.

Motorised monospiral reel

Not suitable

Designed for guided energy chains rather than high-tension monospiral outdoor crane drums.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why must the 24 V DC brake pair and thermal sensor pair be individually screened inside a servo power cable?
Inside a single hybrid jacket, the brake and KTY/PTC sensor pairs lie only millimetres away from the U/V/W phase cores carrying 400–690 V PWM pulses with dv/dt edges exceeding 5 kV/µs. Without an individual foil-and-braid screen around each control pair, capacitive coupling injects high-frequency spikes into the temperature evaluation module or PLC brake relay.
How do I choose between a 1-pair (4G + 1×2) and a 2-pair (4G + 2×2) servo hybrid cable?
Modern digital servo motors using single-cable feedback (EnDat 2.2, HIPERFACE DSL, DRIVE-CLiQ) transmit motor temperature digitally over the encoder cable, so the power cable only needs one screened pair for the 24 V DC holding brake (4G + (2×1.0)C). Legacy SinCos or resolver motors route the PTC/KTY84 thermistor inside the power plug and require the 2-pair version.
Why do larger servo cables (≥ 4G6.0) step up the brake pair from 1.0 mm² to 1.5 mm²?
High-torque servo motors with 6 mm² to 35 mm² phase conductors have much larger spring-applied holding brakes drawing 1.5 A to 3.0 A at 24 V DC. Upgrading the brake pair to 1.5 mm² keeps ohmic voltage drop below 1.2 V over 30–50 m cable runs so the brake releases reliably even at +80 °C coil temperature.
Does UL AWM Style 21223 allow 24 V control pairs and 600/1000 V motor power cores in the same jacket?
Yes. Because both the power cores and the individually screened control pairs are insulated and rated for 1000 V under UL AWM Style 21223 (and tested at 4000 V / 2000 V AC), NFPA 79 and UL 508A permit combining them within a single composite servo cable.
