● Compliant with IEC 60204‑1 and IEC 60364‑5‑52 standards
● PVC insulated cables with copper conductors
● Heat resistance: ambient temperature of 40°C and cable surface temperature of
70°C (Remark: When the ambient temperature exceeds 40°C, contact Inovance.)
● Sysmetric cable with copper‑braided shield
Note
If the recommended cables for peripheral equipment or options are not suitable for the
product, contact Inovance.
To meet the EMC requirements, the cable with the shield must be used. The shielded
cables are divided into three‑conductor cables and four‑conductor cables, as shown
below. If the conductivity of the three‑conductor cable shield cannot meet
requirements, add an independent PE cable. Alternatively, use a four‑conductor cable
with one conductor as the PE wire. The shield of the shielded cable is comprised of
coaxial cooper braids to suppress radio frequency interference. To enhance the
shielding performance and conductivity, the braided density of the shield must be
greater than 90%.

Main circuit routing requirements
The power supply input cable of the AC drive and motor cable can generate strong
electromagnetic interference. To avoid electromagnetic interference caused by long‑
distance parallel coupling between the strong disturbing cable and control circuit
cable, ensure a distance longer than 30 cm between main circuit cables and signal
cables when cabling. Common main circuit cables include input R/S/T cables, output
U/V/W cables, DC bus, and brake cables. Signal cables include I/O signal cables,
communication cables, and encoder cables.
Cable ducts must be in good connection and well grounded. Use aluminum cable
ducts to ensure equipotentiality of the drive. Connect the filter, AC drive, and motor
