Reference selection
The drive selects its command from the configured analog, keypad, or terminal source rather than combining them.

Bulletin 1305 Series C · exact-model technical comparison
Product Introduction
Allen-Bradley 1305-BA02A / 1305-BA01A occupy the low-power end of the 380/460 V Bulletin 1305 Series C drive family. Their main power path rectifies the three-phase supply, maintains the DC link, and switches the motor output, while the regulator applies the selected volts-per-hertz pattern to the commanded frequency.
For field control, 1305-BA02A / 1305-BA01A combine programmable discrete terminals with a voltage-or-current analog reference and configurable status outputs. The BA02A provides the higher motor-output step; keeping the exact catalog number with current and kVA data prevents a low-power frame from being selected by appearance alone.

Installation Highlights — Terminal and Grounding Layout
Correct conductor placement helps 1305-BA02A / 1305-BA01A keep high-energy motor switching away from control references.
Line and motor terminals
Incoming line and outgoing motor conductors stay on the identified power terminals and are not interchanged.
Control-terminal routing
Analog and digital control wiring follows a separate path from motor and braking conductors.
Protective earth and shields
The drive ground and cable shields use short, direct bonds to the grounded enclosure structure.
Ordering and Support Questions
When is 1305-BA02A / 1305-BA01A the wrong pair for an available supply?
1305-BA02A / 1305-BA01A require the 380/460 V three-phase class. If the site supply is 200/230 V or single-phase, a BA catalog number should not be chosen merely by motor horsepower.
What explains a zero-speed result when 1305-BA02A / 1305-BA01A show no active fault?
On 1305-BA02A / 1305-BA01A, verify the selected command source, run input, analog-reference wiring, and programmed minimum and maximum frequency. A healthy power stage can still receive a zero command.
How can unstable analog speed on 1305-BA02A / 1305-BA01A be isolated?
For 1305-BA02A / 1305-BA01A, measure the reference at the control terminals, confirm voltage-versus-current selection, inspect the signal common and shield, and temporarily separate the cable from motor leads.
Why must 1305-BA02A / 1305-BA01A motor data be entered before overload testing?
Electronic protection in 1305-BA02A / 1305-BA01A depends on the configured motor relationship. Incorrect nameplate values can make overload behavior inconsistent with the connected motor.
What catalog details should accompany an order for 1305-BA02A / 1305-BA01A?
An order for 1305-BA02A / 1305-BA01A should retain the full model, input class, motor rating, enclosure, control interface, and any braking or communication accessories.
Can 1305-BA02A / 1305-BA01A be swapped without reviewing the motor circuit?
No. Although 1305-BA02A / 1305-BA01A share a family and voltage class, their output current and motor-power steps differ, so motor suitability and upstream protection must be rechecked.
