Description Product Introduction The ABB RMIO-01C is the main control board for ABB ACS800 drives—the brain that runs the motor control algorithms, processes I/O signals, and handles communication with higher-level systems. This board mounts inside the drive’s control compartment, typically on the swing-out panel or directly above the power section. It’s the single most critical component in the drive: no RMIO, no run. What distinguishes the ABB RMIO-01C from earlier revisions (RMIO-01, RMIO-01B) is the expanded memory and improved I/O handling. The “C” revision has faster processing for the drive’s advanced control algorithms (like DTC—Direct Torque Control) and better support for fieldbus adapters. In my experience, the RMIO-01C is the one to use if you’re replacing a failed board or upgrading an older drive. It works in any ACS800 frame (R2 through R8), though the physical mounting varies by frame size. The board itself is identical across frames—only the mounting bracket changes. Key Technical Specifications Parameter Specification Model ABB RMIO-01C Series ACS800 Function Drive Control Board (CPU) Processor 32-bit (motor control communication) Control Algorithm DTC (Direct Torque Control) Integrated I/O 6 digital inputs, 3 digital outputs, 2 analog inputs, 1 analog output, 1 relay output Communication DDCS fiber-optic (to power section), RS-485 (Modbus RTU), option slot for fieldbus adapters Fieldbus Support PROFIBUS, DeviceNet, CANopen, EtherNet/IP, Modbus TCP (via adapter modules) Encoder Interface Via RDCO option module Status Indication LEDs for power, run, fault, communication Mounting ACS800 drive control compartment (all frames R2–R8) Power Supply 24 VDC from drive power section or external 24 V Operating Temp 0°C to 55°C Programming Drive parameters, PC tools (DriveStudio, Drive Composer) Firmware / Software Versions & Upgrade Notes The ABB RMIO-01C contains firmware that is field-upgradable via the drive’s option slot using a PC and a suitable fieldbus adapter or a dedicated firmware upgrade tool. Minimum firmware: Version 5.0 (required for the RMIO-01C hardware). Version 4.x does not recognize the “C” revision’s expanded I/O capabilities. Recommended firmware: Version 5.2 or later. Version 5.2 fixes a known issue with the analog output scaling when used in torque control mode. Software compatibility: DriveStudio 2.0 or later, or Drive Composer Pro 1.5 or later. DriveStudio 1.x cannot upgrade RMIO-01C firmware. Upgrade procedure: Connect a PC to the drive’s optional fieldbus adapter (or use a dedicated firmware upgrade tool connected to the X5 terminal). Use the software to load the new firmware file. Takes about 5 minutes. Do not interrupt power during upgrade. Rollback: Not recommended. Downgrading firmware can cause parameter corruption. If you must roll back, perform a full parameter backup first and restore after the downgrade. ⚠️ Field note: The ABB RMIO-01C has a battery-backed real-time clock. The battery is a CR2032. If the battery dies, the drive will still run, but fault logs and runtime counters may reset on power cycles. Replace the battery with the drive powered up—the board stays active from the 24 V supply while you swap the cell. Compatibility & Replacement Matrix Original Model Replacement Model Compatibility Level Key Notes ABB RMIO-01 (original) ABB RMIO-01C Drop-in (with parameter check) Same mounting, same connectors. The C revision has faster processing. Parameters from RMIO-01 transfer but may need verification. ABB RMIO-01B ABB RMIO-01C Drop-in Direct swap. The C revision is the final production version. No wiring changes. ABB RMIO-01C (same) ABB RMIO-01C Drop-in Direct replacement. Any C revision is interchangeable. ABB RMIO-02 (different frame) ABB RMIO-01C Incompatible RMIO-02 is for ACS800 liquid-cooled drives or different I/O configuration. Not interchangeable. Third-party control board ABB RMIO-01C Incompatible No substitute. The control board is proprietary to ABB drives. Frequently Asked Questions Q: What ACS800 frames does this board fit? The ABB RMIO-01C fits all ACS800 frame sizes from R2 through R8. The board itself is identical. The mounting bracket varies by frame size—transfer the bracket from the old board to the new one. For frames R2–R4, the board mounts vertically; for R5–R8, it mounts horizontally. Q: How do I transfer parameters to a new RMIO-01C? The parameters are stored on the board itself, not in the power section. If you’re replacing the , you have two options: Use the optional parameter backup module (ACS800-PMP) to save and restore parameters. Use DriveStudio or Drive Composer to upload parameters from the old board (if it still powers up) and download to the new board. If the old board is dead, you’ll need to manually re-enter parameters from a backup sheet. Q: My drive shows “BOARD FAULT” after installing the new RMIO-01C. This usually means the is not communicating with the power section. Check the fiber-optic cables (DDCS) between the control board and the power interface board (AINT or AINP). The cables are polarized—the transmitter (TX) on the RMIO must connect to the receiver (RX) on the power board. Swap the cables if you’re not sure. Q: Does this board support external 24 V for control power? Yes. The has a 24 V input terminal (X5). If you connect an external 24 V supply, the control board stays powered even when the drive main power is off. This keeps the fieldbus communication alive and allows for parameter viewing without running the drive. It’s a common practice in critical installations. Q: What’s the difference between and RMIO-01B? The “C” revision added: Faster processor for DTC algorithms Expanded memory for fieldbus communication buffers Improved analog input filtering Support for newer fieldbus adapters (FENA, FPBA) Electrically and mechanically, they are identical. The C revision is the preferred replacement for any earlier version. Q: My analog input reads incorrectly. Could the RMIO be bad? Possibly, but check the wiring and parameter settings first. The has two analog inputs (AI1, AI2). Verify the input type (0-10 V or 4-20 mA) is set correctly in parameters 12.01 and 12.02. If the wiring and parameters are correct, the input may have failed. You can test by applying a known voltage (like 5 V) and reading the value in parameter 01.17. If it’s off by more than 5%, the analog input circuit is damaged. Q: Can I use this board with an ACS880 drive? No. The is specifically for ACS800 drives. ACS880 uses the ZCU series control units. They are not interchangeable. Q: How do I identify if my board is an without installing it? Look at the white label on the side of the board. The model number is printed clearly: “”. Also, the board has a green PCB with a large processor chip visible. The “C” revision has a slightly different component layout than the “B” revision—the date code on the label is usually 2010 or later. 3BHE024855R0101 PLC 3BSE018291R1 PLC 6SY7010-0AB07 PLC 6SY7010-0AB08 PLC PC834-001-N PLC Email: [email protected] Phone: 86 15340683922 Sales:Wu Jiedong Our products are guaranteed for 1 year, with new and original production stopped and imported spare parts.
