Control and Signal Wiring

General Wiring Information

General requirements for analog signal wire include: stranded copper
0.750-0.283 mm

2

(18-22 AWG), twisted-pair, 100% shield with drain

wire, 300V minimum insulation rating and a temperature rating
suitable for the application (not less than 60 degrees C.) The recom-
mended signal (analog I/O) wire is:

• Belden 8760/9460(or equiv.) – 0.750 mm

2

(18AWG), twisted pair, shielded.

• Belden8770(or equiv.) – 0.750 mm

2

(18AWG), 3 conductor, shielded for remote pot only.

The recommended wire for encoder or pulse inputs/outputs is:

• Lengths less than or equal to 30 meters (98 feet)

Belden 9730(or equiv.) – 0.196 mm

2

(24AWG), individually shielded.

• Lengths greater than 30 meters (98 feet)

Belden 9773(or equiv.) – 0.750 mm

2

(18AWG), twisted pair, shielded.

Signal Connections

If the drive control connections are to be linked to an electronic
circuit or device, the common or 0V line should, if possible, be
grounded at the device (source) end only.

Important:

Signal Common - User speed reference signals are
terminated to logic common at TB2, terminal 5. This puts
the negative (or common) side of these signals at earth
ground potential. Control schemes must be examined for
possible conflicts with this type of grounding scheme.

Shield Termination - TE (True Earth)

The TE terminal block (not available on A Frame drives) provides a
terminating point for signal wiring shields. A Frame drives can use
TB2, terminal 5 for signal wiring shield termination. Refer to

Figure

2.1

for location.

The maximum and minimum wire size accepted by this block is 2.1
and 0.30 mm

2

(14 and 22 AWG). Maximum torque is 1.36 N-m (12

lb.-in.). Use Copper wire Only and always separate control and power
cabling.

Cable Routing

If unshielded cable is used, signal circuits should not run parallel to
motor cables or unfiltered supply cables with a spacing less than 0.3
meters (1 foot). Cable tray metal dividers or separate conduit should
be used.

Important:

When user installed control and signal wiring with an
insulation rating of less than 600V is used, this wiring
must be routed inside the drive enclosure and separated
from any other wiring and/or uninsulated live parts.
