Signals allowed to be run in the same cable
If the voltage of relay control signal is 48 V or below, the signal can be run in the
same cables as digital input signals. The relay-controlled signals should be run as
twisted pairs.
■
Relay cable
The cable type with braided metallic screen (for example ÖLFLEX by LAPPKABEL,
Germany) is tested and approved by ABB.
■
Control panel cable
In remote use, the cable connecting the control panel to the drive must not exceed
100 m (330 ft). If multiple drives are connected, the total length of the panel bus
must not exceed 100 m (330 ft).
The cable type tested and approved by ABB is used in control panel option kits.
Suitable cables are CAT 5e unshielded or shielded twisted pair cables.
■
Drive composer PC tool cable
Use assistant control panel or RDUM-01 panel to connect the drive composer PC
tool with the drive. Use USB type A (PC) - type B (control panel) cable for assistant
control panel and BCBL-01 for RDUM-01 panel. The maximum length of the cable
must not exceed 3 m (9.8 ft).

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.
