ALLEN-BRADLEY / BULLETIN 1305
1305-BA04A
Adjustable Frequency AC Drive
The 1305-BA04A belongs to the Allen-Bradley Bulletin 1305 adjustable frequency AC drive family and is configured for three-phase 380–460 V AC applications. Its 1.5 kW (2 HP) rating and 4.0 A output rating make it a practical fit for compact motor-speed control duties where configurable frequency control, acceleration/deceleration adjustment and multiple control interfaces are required.

TECHNICAL CORE
1305-BA04A
|
The BA04A configuration is the 2 HP member of the 380–460 V three-phase portion of the Bulletin 1305 range. At 380 V input, its rated output current is 4.0 A; at 415 V and 460 V, the corresponding listed current capability is higher than the 380 V base value, subject to the applicable drive conditions and derating requirements. |

OUTPUT STAGE
3-Phase IGBT
The drive uses a three-phase output stage with sine-weighted PWM. Carrier frequency is adjustable from 2 kHz to 8 kHz in 100 Hz increments, with output-current derating above 4 kHz. |
The Bulletin 1305 family covers multiple motor ratings across 200–230 V and 380–460 V AC three-phase configurations. The BA04A occupies the 2 HP / 1.5 kW position within the 380–460 V group, between the smaller BA03A and larger BA06A configurations.

| 1305-BA01A | 380–460 V AC | 0.37 kW / 0.5 HP | 1.3 A at 380 V |
| 1305-BA02A | 380–460 V AC | 0.55 kW / 0.75 HP | 1.6 A at 380 V |
| 1305-BA03A | 380–460 V AC | 0.75 kW / 1 HP | 2.3 A at 380 V |
| 1305-BA04A | 380–460 V AC | 1.5 kW / 2 HP | 4.0 A at 380 V |
| 1305-BA06A | 380–460 V AC | 2.2 kW / 3 HP | 6.0 A at 380 V |
| 1305-BA09A | 380–460 V AC | 4.0 kW / 5 HP | 9.0 A at 380 V |
|
FIELD FIT
Application Logic
The 1305-BA04A is best considered where a three-phase induction motor requires adjustable-speed operation and the installation can accommodate the drive's 380–460 V input class and 2 HP output rating. |
|
| Motor does not accelerate properly
Check motor connections, mechanical loading, control input states, acceleration settings, current limit and boost parameters. |
Speed command is incorrect
Confirm the selected frequency source and verify the configured frequency command or active adapter. |
| Drive will not operate without HIM
Verify the SW1/SW2/SW3 configuration and confirm the frequency source and command settings. |
Adapter-related fault
Check the Logic Mask, confirm the adapter is not the active frequency source, and inspect the communication connection. |
