The BUS Supply should have the following characteristics:
Must provide safety isolation from the power line
Can be regulated or unregulated
Bus Supply Return is connected to the Control Supply Return and I/O
RTN in the drive
Typical BUS Supply:
Unregulated, Isolating, step down transformer with secondary rectified
into capacitive filter
BUS Supply Return is connected to earth ground
10 ft maximum
16 AWG (minimum)
Twisted pair
Daisy chaining of multiple drives is acceptable
No contactor or switching in the BUS wiring
+ 10 VDC to +90 VDC
Isolating
Unregulated or Regulated
Common GND with bus supply and I/O RTN
20 watt supply or 1 amp short circuit
Wire control (J1-1) to bus (J1-3)
or
Wire control (J1-1) to separate supply to preserve status and fault
information. (+ 10 VDC to + 30 VDC supply can be shared by Control
and I/O)
