More Information

Overview Manuals Order Code Motor and Feedback Commissioning Application
  • C power option for 40–85 V AC or 60–120 V DC operation at the documented 5 A class
  • E encoder-feedback option with R serial RS-232, RS-422, or RS-485 communication
  • A option includes the documented firmware feature set for stand-alone or host operation

SB1381-C-E-R-A is a one-axis digital servo controller configured by its complete C-E-R-A order suffix.

It combines high-rate servo control, encoder feedback, isolated I/O, serial host connectivity, and programmable stand-alone/PLC behavior in one controller.

Before replacement, archive tuning and motion logic, then match the motor, feedback device, bus supply, serial mode, I/O, mechanics, and firmware features.

Availability, condition, price, and shipping time for SB1381-C-E-R-A are confirmed during quotation.

  • C identifies the documented power-input and 5 A current class
  • E selects encoder feedback while R selects serial host communication
  • A denotes inclusion of the documented firmware-option set
  • Motor type, encoder data, commutation, and feedback polarity must match
  • Automatic sinusoidal commutation does not remove the need for correct motor setup
  • Retain current, velocity, and position-loop tuning before controller exchange
  • Restore the application, I/O logic, serial settings, and motion limits
  • Prove feedback direction and loop stability at controlled energy
  • Validate travel, braking, fault response, and the complete loaded motion cycle
  • Single-axis AC-servo positioning with encoder feedback
  • Stand-alone programmable motion with isolated machine I/O
  • Host-controlled motion through RS-232, RS-422, or RS-485 communication
Description
SB1381-C-E-R-A is an ACS Motion Control single-axis digital servo controller configured by its complete C-E-R-A order suffix.

The controller combines encoder feedback, high-rate current and motion processing, isolated I/O, serial host communication, and programmable stand-alone or PLC-coordinated operation.

Before replacement, preserve the motion program and tuning, then match the power option, motor, feedback device, serial mode, I/O logic, mechanical load, and enabled firmware functions.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why must every suffix be matched when ordering ACS Motion Control SB1381-C-E-R-A?
Each suffix defines a functional choice: C power class, E encoder feedback, R serial communication, and A firmware options. A base SB1381 with different suffixes can be electrically or functionally unsuitable.
What motor and feedback information should be retained before replacing ACS Motion Control SB1381-C-E-R-A?
Retain motor type, winding data, encoder type and resolution, commutation settings, polarity, cable pinout, and all tuned current, velocity, and position-loop parameters.
Can ACS Motion Control SB1381-C-E-R-A be connected to any available DC bus?
No. Verify the documented C-option power range, bus polarity, regenerative behavior, source capacity, grounding, and protective devices before energizing.
What can prevent host communication after installing ACS Motion Control SB1381-C-E-R-A?
A wrong RS-232/422/485 mode, connector pinout, termination, address, baud setting, cable reference, or host protocol can leave the controller powered but unreachable.
What should be backed up from ACS Motion Control SB1381-C-E-R-A before removal?
Back up the motion program, I/O assignments, firmware-option use, motor and encoder configuration, tuning values, limits, homing logic, serial settings, and fault history.
Why should mechanical and regeneration conditions be reviewed for ACS Motion Control SB1381-C-E-R-A?
Load inertia, braking energy, duty cycle, cooling, and enclosure mounting affect stability and thermal performance even when the electrical suffix matches.
What commissioning sequence is appropriate for ACS Motion Control SB1381-C-E-R-A?
Verify wiring and limits with power isolated, confirm feedback direction at low energy, test current and velocity loops, validate travel and protection logic, then prove the complete motion cycle under controlled load.
