￭
Signals that can be run in the same cable
If their voltage does not exceed 48 V, relay-controlled signals can be run in the
same cables as digital input signals. The relay-controlled signals should be run as
twisted pairs.
￭ Relay cable
Recommend to use the cable type with braided metallic shield.
￭
Control panel to drive cable
Use EIA-485 with male RJ-45 connector, cable type Cat 5e or better. The maximum
permitted length of the cable is 100 m (328 ft).
￭ PC tool cable
Connect the Drive composer PC tool to the drive through the USB port of the
external assistant control panel. Use a USB Type A (PC) - Type Mini-B (control panel)
cable. The maximum length of the cable is 3 m (9.8 ft) or use the BCBL-01 USB to
EIA-485 cable to connect the drive with PC directly. .
Routing the cables
￭ General guidelines – IEC
• Route the motor cable away from other cables. Motor cables of several drives
can be run in parallel installed next to each other.
• Install the motor cable, input power cable and control cables on separate trays.
• Avoid long parallel runs of motor cables with other cables.
• Where control cables must cross power cables, make sure that they are
arranged at an angle as near to 90 degrees as possible.
• Do not run extra cables through the drive.
• Make sure that the cable trays have good electrical bonding to each other and
to the grounding electrodes. Aluminum tray systems can be used to improve
local equalizing of potential.
The following figure illustrates the cable routing guidelines with an example drive.
Note: When motor cable is symmetrical and shielded and it has short parallel runs
with other cables (< 1.5 m / 5 ft), distances between the motor cable and other
cables can be reduced by half.
