28 Electrical planning guidelines

Selecting the control cables

￭

Shielding

Only use shielded control cables.
Use a double-shielded twisted pair cable for analog signals. This type of cable is
recommended for the pulse encoder signals also. Employ one individually shielded pair for
each signal. Do not use common return for different analog signals.
A double-shielded cable (figure a below) is the best alternative for low-voltage digital signals
but single-shielded (b) twisted pair cable is also acceptable.

￭

Signals in separate cables

Run analog and digital signals in separate, shielded cables. Do not mix 24 V DC and
115/230 V AC signals in the same cable.
￭

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 type

The cable type with braided metallic screen (for example ÖLFLEX by LAPPKABEL, Germany)
has been tested and approved by ABB.
￭

Control panel cable length and type

In remote use, the cable connecting the control panel to the drive must not be longer than
three meters (10 ft). Cable type: shielded CAT 5e or better Ethernet patch cable with RJ-45
ends.
