BALDOR FD2A05TR-RN20 – High-Performance AC Servo Amplifier | FlexDrive II Series
Engineering Background
The BALDOR FD2A05TR-RN20 is a member of the FlexDrive II family — BALDOR’s second-generation compact AC servo amplifier platform engineered for demanding motion control applications. Designed to deliver precise torque, velocity, and position control, the FD2A05TR-RN20 integrates seamlessly into multi-axis machine architectures where reliability and dynamic response are non-negotiable.
Product Positioning
Targeting OEM machine builders, system integrators, and MRO procurement engineers, the FD2A05TR-RN20 occupies the mid-range power tier of the FlexDrive II lineup. Its 5A continuous output rating makes it ideal for compact servo axes in packaging, semiconductor handling, CNC, and precision assembly equipment. At Konmask.com, every unit is sourced from verified supply channels and undergoes functional inspection prior to dispatch.

- BALDOR / ABB Ecosystem – Direct compatibility with BALDOR BSM and BSE servo motor families
System Architecture & Signal Flow
The FD2A05TR-RN20 operates as a closed-loop servo amplifier within a standard motion control hierarchy:
- Motion Controller / PLC issues ±10 V analog velocity/torque command or step-direction position pulses
- FD2A05TR-RN20 Amplifier receives command signal, closes the current loop at 10 kHz PWM, and drives the servo motor
- Servo Motor (BALDOR BSM/BSE) generates torque; encoder or resolver feedback is returned to the amplifier’s feedback port
- Position Loop (optional) closed externally at the motion controller using encoder pass-through signals
- I/O Interface provides enable, fault relay, and limit switch inputs for machine safety integration

Technical FAQ
- Q: Is the FD2A05TR-RN20 compatible with third-party servo motors?
- A: Yes, provided the motor’s feedback type (resolver for RN20 variant) and current rating are within the amplifier’s specifications. Motor parameter configuration is required via BALDOR’s setup software.
- Q: What is the difference between FD2A05TR-RN20 and FD2A05TR-RN00?
- A: The RN20 suffix denotes the resolver feedback interface option. RN00 typically indicates no resolver option or a different feedback configuration. Always verify the suffix against your motor’s feedback device.
- Q: Can this drive operate on single-phase 240 VAC?
- A: Yes. The FlexDrive II accepts single-phase 120/240 VAC input, though three-phase input is recommended for full rated output current and reduced input ripple.
- Q: Do you provide the original BALDOR setup software and documentation?
- A: BALDOR’s DriveWare configuration software and the FD2 series user manual are publicly available from ABB/BALDOR’s support portal. Konmask.com can provide links upon request.
- Q: What warranty applies to this unit?
- A: Konmask.com offers a 30-day DOA (Dead on Arrival) guarantee. Extended warranty options are available — contact us for details.
