Central unit
The "Line_Term" switch.
The "Line_Term" switch identifies which are the elements that occupy the ends of the CAN bus; i.e.
the first and last physical element in the connection.
The central unit must always be at one end of the line. The other end will be the last one of the remote
module groups.
The switch of the elements at the ends must be in the "1" position and the rest of the elements in
the "0" position. The CNC does not have a switch and always has the terminating resistor activated.
Characteristics of the CAN cable.
Use a specific CAN cable. The ends of all the wires and the shield must be protected by the
corresponding terminal (pin). Also use the terminals (pins) to secure the cable to the connector.
Type: Shielded. Twisted pairs (1 x 2 x 0,22 mm
2
).
Flexibility: Extremely flexible. Minimum bending radius, static = 50 mm and dynamic
= 95 mm.
Cover: PUR
Impedance: Cat.5 (100 - 120 )
CAN connector pinout.
5-pin male Phoenix minicombicon connector (3.5 mm pitch).
The connector has two shield pins. Both pins are equivalent; the CAN shield may be connected to
either one.
