ABB SNAT 617 CHC – Gate Drive & Firing Control Module | ACS 600 / ACS 800 Series
Engineering Background
The SNAT 617 CHC is a precision gate drive and firing control board engineered by ABB for use within the ACS 600 and ACS 800 family of medium-voltage AC drives. Designed to interface directly with IGBT/thyristor power stacks, this module governs the precise timing and sequencing of switching pulses that determine motor torque, speed stability, and drive protection response. In high-demand industrial environments — from steel rolling mills to marine propulsion systems — the integrity of this board is mission-critical.

Engineering Advantages
- Precision Firing Timing: Ensures accurate IGBT gate pulse sequencing, minimizing switching losses and harmonic distortion in the output waveform.
- Integrated Fault Detection: Onboard diagnostics report gate drive faults back to the drive’s main control unit via DDCS, enabling rapid fault isolation.
- Thermal Resilience: Designed for sustained operation in high-ambient drive cabinets with robust component derating margins.
- Direct OEM Replacement: Pin-compatible and firmware-transparent — no parameter re-configuration required upon swap-out in most ACS 600/800 configurations.
- Fiber-Optic Isolation: Galvanic isolation between control and power sections eliminates ground loop interference and protects upstream PLC/DCS systems.
System Architecture & Signal Flow
Within the ACS 600/800 drive architecture, the SNAT 617 CHC sits between the main control board (NAMC / RMIO) and the IGBT power module stack. The control board issues speed/torque reference commands via the internal DDCS fiber-optic ring. The SNAT 617 CHC receives these commands, translates them into precise gate pulse trains, and drives the IGBT gates through isolated gate driver circuits. Simultaneously, it monitors gate voltage feedback and overcurrent signals, feeding fault status back to the NAMC board in real time. This closed-loop architecture ensures sub-millisecond fault response and protects the power semiconductors from shoot-through and desaturation events.

Technical FAQ
Q: Is the SNAT 617 CHC compatible with both ACS 600 and ACS 800 drives?
A: The SNAT 617 CHC is primarily designed for the ACS 600 platform. Compatibility with specific ACS 800 variants depends on the drive’s power rating and hardware revision. Please provide your drive’s type code for confirmation before ordering.
Q: Can this board be replaced in the field without ABB service tools?
A: In most cases, yes. The board is a direct plug-in replacement. However, some ACS 600 configurations may require a parameter download from the NAMC board after replacement. We recommend consulting the drive’s hardware manual (3AFY58919285) or contacting our technical team.
Q: Do you supply refurbished units, and how are they tested?
A: We supply both new and professionally refurbished units. Refurbished boards are cleaned, re-soldered at critical joints, and functionally tested on a drive test bench. Condition is clearly stated on the invoice.
Q: What is the typical lead time for stock items?
A: In-stock units ship within 1–3 business days. For sourced or refurbished units, lead time is typically 7–15 business days depending on origin.
Q: Can you provide a test report or inspection certificate?
A: Yes. A pre-shipment inspection report is available for all orders. Third-party inspection (SGS, BV) can be arranged for large-volume orders at buyer’s cost.
