The following table illustrates the technical characteristics of all cables:
Cables (as norm EN60204)
Type Section Notes
for the
Main Supply
1.5mm
2
/15AWG
Always insert a power relay or a thermal
magnet on every phase of the products power
supply.
for the
Auxiliary
Supply
1.5mm
2
/15AWG
Connect the 0V of the auxiliary supply to the ground
bar.
for the
Motor's Brake
0.75mm
2
It must shielded.
for the
Motor's Power
1.5mm
2
/15AWG
It must be shielded.
It must have a capacity of ≤150pF/m.
In the conguration without lter, the cable can
reach a maximum length of 20/25m. If the length
exceeds 20/25m, insert an Axor 3x1.2mH lter.
for the
Control signals
and
I/O signals
from PLC/CNC
0.5mm

/20AWG See "2.6 Note about cable shielding"
for the
Encoder signals
0.25-0.35mm
2
/
22-24AWG
It must be shielded.
It must have a capacity less than 120pF/m(25m
max. length).
for the
Resolver signals
0.25-0.35mm
2
/
22-24AWG
for external
resistor
1.5mm
2
/15AWG
for the RS232
communication
0.22mm
2
/24AWG or
0.34mm
2
/22AWG
The length of the cable must be equal to or less
than 2.5m.
It must be connected when the main supply and the
auxiliary supply are both powered off.
It must have a capacity less than 160pF/m.
for the
CanBus
communication
0.25mm
2
/0.34mm
2
Cable capacitance: max 60 nF/km.
Impedance characteristics : 100...120Ω.
Lead resistance (loop): 159,8 Ω/km
The length depends upon the transmission speed:
• 1000kbit/s 20m max;
• 500kbit/s 70m max;
• 250kbit/s 115m max.
Note:
• Avoid crossing, overlapping and twisting cables together. If it is absolutely necessary to cross them,
do so at 90°.
• On request Axor provides motor signal cables series encoder or resolver for motors series Super-
SAX.
