Three selector inputs
SW1, SW2, and SW3 on 160-BA01NPS1 / 160-AA02NPS1 create the binary combinations used for the eight presets.
Allen-Bradley 160-BA01NPS1 / 160-AA02NPS1 preset-speed drives
Model Overview
Allen-Bradley 160-BA01NPS1 / 160-AA02NPS1 are Bulletin 160 SSC variable speed drives with the Preset Speed control option. Each drive converts a three-phase mains input into variable-frequency, three-phase motor output for a 0.37 kW motor, while the BA01 and AA02 power sections serve different incoming voltage classes.
Preset commands enter 160-BA01NPS1 / 160-AA02NPS1 through SW1, SW2, and SW3 at terminal block TB3. Dry contacts or open-collector devices switch these inputs against the internal 12 V control supply, and the three-input combination selects one of the eight frequencies stored in parameters 61 through 68.
Although their motor rating is common, 160-BA01NPS1 / 160-AA02NPS1 connect to different supplies. The BA01 power stage accepts the 380-460 V class, while the AA02 power stage accepts the 200-240 V class; each stage then produces the current associated with its own voltage class rather than sharing one interchangeable mains connection.

Configuration and Programming — Preset-Speed Selection
The PS1 control in 160-BA01NPS1 / 160-AA02NPS1 converts three discrete selector inputs into eight stored output-frequency choices.
Stored frequency values
Parameters 61–68 hold the preset frequencies used by 160-BA01NPS1 / 160-AA02NPS1.
Keypad changes
A Program Keypad Module is required when the factory preset values in 160-BA01NPS1 / 160-AA02NPS1 must be changed.
Operating Characteristics — Two Voltage Classes
The common 0.37 kW rating in 160-BA01NPS1 / 160-AA02NPS1 is delivered from two different three-phase supply classes.
High-voltage input
The BA01 member of 160-BA01NPS1 / 160-AA02NPS1 uses 380–460 V AC and a 1.2 A output rating.
Low-voltage input
The AA02 member of 160-BA01NPS1 / 160-AA02NPS1 uses 200–240 V AC and a 2.3 A output rating.
Motor-side control
Both 160-BA01NPS1 / 160-AA02NPS1 convert their respective mains input into variable-frequency three-phase motor output.
Common Product Questions
Why are 160-BA01NPS1 / 160-AA02NPS1 not interchangeable on the same incoming supply?
The BA01 member of 160-BA01NPS1 / 160-AA02NPS1 requires 380–460 V three-phase input, while AA02 requires 200–240 V three-phase input. Their shared horsepower does not override this supply difference.
How are the eight speeds selected on 160-BA01NPS1 / 160-AA02NPS1?
Dry contacts or open-collector devices switch SW1, SW2, and SW3 at TB3 on 160-BA01NPS1 / 160-AA02NPS1. The three-input combination selects one of the eight stored preset-frequency parameters.
Why might a replacement 160-BA01NPS1 / 160-AA02NPS1 run at the wrong preset frequencies?
The stored parameter values in 160-BA01NPS1 / 160-AA02NPS1 may not match the commissioned drive. Compare parameters 61–68 and use the Program Keypad Module when the defaults need to be changed.
What wiring reference must be shared when one selector controls several 160-BA01NPS1 / 160-AA02NPS1 drives?
When a common preset-speed input operates multiple 160-BA01NPS1 / 160-AA02NPS1 drives, their TB3-7 commons must be connected as specified. If that chain is tied to another common, make the tie at one point only.
When is the optional 24 V interface relevant to 160-BA01NPS1 / 160-AA02NPS1?
For control wiring longer than 15 m (50 ft), the optional 24 V DC interface is recommended for 160-BA01NPS1 / 160-AA02NPS1. It supports noise immunity where the internal 12 V input path would otherwise run over a long field cable.
Does IP20 allow 160-BA01NPS1 / 160-AA02NPS1 to operate as outdoor enclosures?
No. The N enclosure code in 160-BA01NPS1 / 160-AA02NPS1 is an IP20 open-style construction. The installation must provide the environmental and access protection required around the drive.
