Features:
- Provides Reliable Interface Between RMIO Control Board And IGBT Power Modules.
- Supports High-Frequency Switching And Stable Motor Output Up To 500 Hz.
- Designed For Robust Operation In Industrial Environments With Auxiliary Power Support.
The ABB GINT-6611C is the core main circuit board for ACS800 series high-power frequency inverters. It serves as the link between the RMIO control unit and the IGBT power semiconductors, ensuring accurate voltage and frequency delivery to the connected motor. The board provides auxiliary +24 V DC power and a +10 V DC reference voltage to support connected devices and enhance system stability.
Engineered for high-performance industrial applications, the GINT-6611C allows switching frequency control typically between 2 kHz and 8 kHz, enabling precise modulation of the drive system. It is tested for insulation withstand up to 1000 V DC, providing electrical safety and reliability for long-term operation.
The board operates at rated temperatures up to 50 °C without derating and can be stored in environments with 5% to 95% relative humidity, non-condensing. Proper installation with recommended tightening torque of 30 N·m for motor cable terminals ensures secure connections and consistent performance, making it suitable for demanding ACS800 drive applications.
The GINT-6611C 68577349 ABB Main Circuit Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Hardware Version Replacement: The GINT-6611C is an optimized version of the earlier GINT series, enhancing electromagnetic compatibility (EMC) in high-harmonic environments.
- Critical Component Lifespan: This board integrates large-capacity filter capacitors; preventative replacement or full board refurbishment is recommended after 6 to 9 years of operation, according to the ABB maintenance manual.
- Conformal Coating Reinforcement: Newer spare parts typically use a higher level of conformal coating to withstand corrosive gases from environments such as chemical plants.
- Interchangeability Check: When replacing with a new board, verify that its version number (e.g., Rev. G or higher) is compatible with the firmware version of the existing RMIO control board.
- Non-Direct Programming Logic: The board itself does not directly support user application programming; logic is transmitted from the upper-layer RMIO control board via fiber optic cable or ribbon cable.
- Current Transformer Calibration: After replacing this board, it is usually necessary to access the inverter parameter group via DriveWindow software or the control panel to verify the current measurement offset.
- Drive Parameter Matching: The frame size (e.g., R7 or R8) must be correctly set in the inverter firmware to ensure that the protection threshold of the GINT board matches the power hardware.
- STO Safety Configuration: If the safety torque interruption function is involved, a closed-loop test of the onboard safety circuit is required to ensure that the signal trigger time meets the SIL 3 standard value.
- ACS800-01/04 Single-Unit Drive: Widely used in the core control of wall-mounted or cabinet-type inverters in the 90kW to 200kW range.
- Heavy-Duty Lifting Equipment: Responsible for accurate torque calculation and IGBT triggering in the frequency converter control system of tower cranes and mining hoists.
- Extreme industrial environments: Used in dusty and high-temperature environments such as paper mills and metallurgical plants, serving as an electrical isolation barrier between power units and control units.
- Multidrive systems: Used as the core board of independent inverter units in large paper machine or continuous rolling mill production lines.
