Zapi FZ5376-ACE2 Controller

The Zapi FZ5376‑ACE2 is a high‑current (36–48 V, up to 450 A) AC motor controller used in forklifts and other industrial traction applications. Common failure points include the IGBT module or gate driver ICs overheating, capacitor degradation on the DC link, and faulted MOSFET gates due to overvoltage spikes; these often manifest as a loss of motor drive or an “over‑current” error code. First‑check diagnostics should verify that the input supply voltage is within spec, inspect all IGBTs and gate driver chips for visible burn marks or excessive heat, and review any stored fault codes in the controller’s diagnostic interface.[oss-gpt-20b] Post Comment
