Source mode
In SRC mode, 18…24 V applied to an input is the ON state and 0…6 V is OFF. The field device supplies the positive control signal to the selected terminal.

Product Description
Allen-Bradley 22A-A1P5N104, 22A-A2P3N104 and 22A-A4P5N104 are compact PowerFlex 4 variable-frequency drives for running three-phase induction motors from a 200…240 V single-phase branch. Mounted in the machine panel ahead of the motor, they provide adjustable speed, forward/reverse control and programmable acceleration or stopping for small fans, pumps, conveyors, machine tools and material-handling equipment.
In 22A-A1P5N104, 22A-A2P3N104 and 22A-A4P5N104, incoming single-phase power is rectified to the DC bus and the inverter creates 0…230 V three-phase motor output. The fixed keypad and potentiometer provide local operation; dedicated stop, start and reverse terminals, two programmable digital inputs, one isolated analog speed input, a Form C relay and integral RS-485 DSI provide the external command, reference and status paths.
Control wiring on 22A-A1P5N104, 22A-A2P3N104 and 22A-A4P5N104 uses a DIP switch to make the 24 V digital-input circuit operate as sink or source logic, and the terminal connections must follow that selection. A factory jumper completes the stop circuit for keypad operation; terminal-controlled machines replace it with the required normally closed stop path, while the motor rating selects the appropriate model within the otherwise common control arrangement.

Sink/Source Control Wiring
A control-logic DIP switch changes how the 24 V digital inputs are referenced, so the terminal circuit and switch position must be planned as one electrical arrangement.
Sink mode
In SNK mode, 0…6 V is the ON state and 18…24 V is OFF. The field circuit therefore pulls the input toward digital common rather than applying the source voltage.
Factory jumper
A jumper between Stop and the internal 24 V point permits keypad operation in the shipped configuration. Removing it without providing the required closed stop circuit prevents the drive from starting.
Start, Reverse and Speed References
Dedicated run inputs establish the basic motor commands, while programmable terminals and one active analog channel extend the operating sequence.
Two-wire or three-wire control
The Stop, Start/Run Forward and Direction/Run Reverse terminals can be assigned for two-wire or three-wire operation. The selected scheme must match the physical contact logic.
Programmable inputs
Digital Inputs 1 and 2 can select preset frequencies, jog, local control, second acceleration/deceleration, fault clearing, RS-485 control or an auxiliary fault.
Analog reference choice
Speed can follow either the 0…10 V input or the 4…20 mA input. Connecting both as simultaneous frequency references produces an undefined reference and is not a valid control arrangement.
Frequently Asked Questions
How are 22A-A1P5N104 / 22A-A2P3N104 / 22A-A4P5N104 separated during selection?
The output current and motor rating rise from the 0.2 kW model through the 0.75 kW model. Their Frame A outline and 240 V single-phase input are shared, so motor sizing supplies the decisive difference.
What happens if the sink/source switch is wrong on 22A-A1P5N104 / 22A-A2P3N104 / 22A-A4P5N104?
The ON and OFF voltage interpretation no longer matches the field-device wiring. A command can remain inactive or behave opposite to the intended circuit until the switch and wiring method agree.
Why is the Stop jumper present on 22A-A1P5N104 / 22A-A2P3N104 / 22A-A4P5N104?
The factory jumper completes the stop circuit for keypad operation out of the box. A terminal-controlled installation replaces that jumper with the required normally closed stop path.
Can two analog references be connected to 22A-A1P5N104 / 22A-A2P3N104 / 22A-A4P5N104?
Only one analog frequency source is used at a time on PowerFlex 4. Simultaneous voltage and current references can produce an undetermined frequency command.
Which serial terminal belongs to 22A-A1P5N104 / 22A-A2P3N104 / 22A-A4P5N104?
The integral RS-485 DSI connection uses its shield terminal bonded to protective earth. The serial route can support PC programming or an RTU multi-drop network.
What panel space is common to 22A-A1P5N104 / 22A-A2P3N104 / 22A-A4P5N104?
All three use the Frame A outline of 80 × 152 × 136 mm and an approximate shipping weight of 1.4 kg. Cable bends and environmental enclosure space remain additional installation allowances.
