Note on laying SMI wires in
custom cables
The I+ and I- SMI wires can be laid in the motor connec
-
tion line of the SMI drive (as above) or in their own cable.
It is not permitted to lay SMI wires together with wires
carrying other signals in one cable.
If SMI drives wired in parallel are supplied with electrical
power from different phases, the SMI I+ and I- wires
must be laid in a separate cable.
