- 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
