Bulletin 160 Series C SSC · exact-model technical comparison
Product Details
Allen-Bradley 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 are low-power 380…460 V Bulletin 160 Series C SSC drives fitted with the SF1 analog signal follower interface. Each converts the three-phase line into adjustable motor frequency, while the SF1 control path turns a voltage or current reference into the commanded output speed.
At the terminals, 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 combine programmable digital inputs with the analog reference, relay status, and the main motor-power connections. The catalog progression changes the available output current and motor size without changing the basic relationship between the field reference, ramp logic, PWM regulator, and motor output.

Configuration and Programming — Analog Signal Follower Setup
The SF1 interface in 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 must be aligned with the field reference and run logic.
Voltage or current reference
Input selection and wiring must agree with the actual 0…10 V or 4…20 mA source.
Minimum and maximum speed
Programmed limits map the usable analog span into the required motor-frequency range.
Start and direction inputs
Digital terminals determine whether the valid analog command is allowed to run the motor and in which direction.
Selection and Use Questions
How are 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 distinguished when ordering?
Keep each 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 model with its output current and motor kilowatts; SF1 identifies the shared analog interface, not an identical power stage.
Why does 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 stay at minimum speed with a live reference?
Check the SF1 voltage/current selection, signal common, programmed minimum and maximum frequency, digital run input, and reference scaling on 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1.
What wiring practice helps a stable command on 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1?
Use shielded analog cable for 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1, terminate the shield as specified, and keep it apart from line and motor conductors.
Can 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 use the same upstream protection?
Not by assumption. The input and output demands of 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 differ, so branch devices must be selected for each catalog number.
What should be checked if 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 trip only under load?
Compare motor current, programmed motor protection, mechanical load, acceleration time, ventilation, and supply condition for the installed 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1 model.
Why is a control-terminal photo useful before removing 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1?
A photo preserves the analog reference, common, run, direction, and relay connections for 160-BA01NSF1 / 160-BA02NSF1 / 160-BA03NSF1, reducing the chance of moving a low-level signal to the wrong terminal.
