Vertex-Pro Motor-Driven Compressor Control
Woodward
29
When using load sharing a maximum of three parallel compressor controls can
be connected by CAN communication. Redundant CAN communication can be
performed by using both CAN #1 and CAN #2 ports on the CPU module. Figure
5-11 is the example of single CAN communication with redundant CPU hardware
configuration.

5.1.10—CAN Cable Specification
Thick cable is preferred and recommended for all uses. Most CAN / DeviceNet™
(trademark of ODVA, Inc.) cable is not rated for temperatures above 80 °C so be
careful during installation to avoid hot routing areas. Always use shielded cables
for improved communications in industrial environments.
Impedance:
120
Ω
10% at 1 MHz
DC resistance:
< 7
per 1000 ft.
Cable capacitance:
12 pF/ft at 1 kHz
Propagation delay
1.36 ns/ft (maximum)
Data Pair:
19 strands, 1.0 mm² corresponds to 18 AWG, individually tinned, 3 twists/foot
Power Pair:
19 strands, 1.5 mm² corresponds to 15 AWG, individually tinned, 3 twists/foot
Drain / Shield Wire:
19 strands Tinned Copper shielding braid or shielding braid and foil
Cable type:
twisted pair cable. 2x2 lines
Bend Radius:
20x diameter during installation or 7x diameter fixed position
Signal attenuation:
0.13 dB/100 ft @ 125 kHz (maximum)
0.25 dB/100 ft @ 500 kHz (maximum)
0.40 dB/100 ft @ 1000 kHz (maximum)
