Bus Supply Characteristics

The BUS Supply must meet the following requirements:

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 a capacitive filter.Note: BUS Supply Return is connected to earth ground.

Wiring from BUS Supply to Drive

Maximum length: 10 ft
Minimum wire gauge: 16 AWG
Wire type: Twisted pair
Daisy chaining of multiple drives is acceptable.
No contactor or switching allowed in the BUS wiring.

Control Voltage (J1-1 to J1-2)

+10 VDC to +90 VDC

Control Supply Type

Isolating
Unregulated or Regulated
Common GND with bus supply and I/O RTN
20-watt supply or 1-amp short circuit capacity

Control Supply Wiring

Option 1: Wire control (J1-1) to bus (J1-3)
Option 2: Wire control (J1-1) to a separate supply to preserve status and fault information.

(+10 VDC to +30 VDC supply can be shared by Control and I/O)

Control Supply Current

20 to 110 mA at 75 VDC
60 to 330 mA at 24 VDC
125 to 660 mA at 12 VDC

NOTEDo not allow the Bus Voltage to exceed +90 VDC. This will cause damage to the drive.Target design center voltage for unregulated supplies: +70 to +75 VDC. This provides 15 to 20 VDC margin for line tolerance, transformer regulation, and regen pump-up.Design center voltage for regulated supplies can be up to +80 VDC.
