Requirements
ALL
Differential Stepper
/ Encoder Signals
1. Screened, twisted pair cable
2. Connect screen to metal chassis at both ends
(See Cable Shields on page 11 and Product
Technical Manual)
3. 0V reference connected at both ends
ALL
CAN bus
1. Screened, twisted pair cable with
characteristic impedance of 120 Ohm (±10
Ohm)
2.
Connect screen to Chassis at every node
ALL
Digital I/O
1. It is highly recommended to separate PSU
and 0V return (the I/O is internally isolated)
ALL
ADC / DAC
1. Use DAC 0V reference pin not common 0V
ALL
RS232 / RS422 /
RS485 Serial ports
1. Screened cable
2. Connect screen to Chassis at both ends
3. 0V reference connected at both ends
4. (See cable shields, page 11 and in Product
Technical Manual)
ALL
Ethernet
1. Overall Foil Braided Shield / Unshielded
Twisted Pair, (Compliant with Industrial SF/
UTP and TIA Cat5e, minimum)
2. Cable ≤30m in length
ALL
EtherCAT
1. Overall Foil Braided Shield / Unshielded
Twisted Pair, (Compliant with Industrial SF/
UTP and TIA Cat5e, minimum)
2. Connect screen to Chassis at both ends, this
is achieved by the shield connection built in
to the RJ45 socket
3. Cable ≤30m in length
