Selecting the control cables
All control cables except 220 V or 115 V must be shielded.
Use a double-shielded twisted pair cable (Figure a, e.g. JAMAK by NK Cables,
Finland or BELDEN type, USA) for analogue 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 analogue signals.
A double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded twisted multipair cable (Figure b) is also usable.
Run analogue and digital signals in separate, shielded cables.
Relay-controlled signals, providing their voltage does not exceed 48 V, can be run in
the same cables as digital input signals. It is recommended that the relay-controlled
signals be run as twisted pairs.
! Never mix 24 VDC and 115/230 VAC signals in the same cable .
DCS800 panel cable
The cable connection of the DCS800 panel to the drive must not exceed 3 meters
(10 ft). The cable type tested and approved by ABB is used in control panel option
kits.
