Glentek GA4569P-1 Servo Amplifier

The Glentek GA4569P‑1 is a high‑performance analog PWM servo amplifier used to drive DC brush or brushless servomotors in CNC routers and industrial automation systems. Common failure points for this model include overheating of the power MOSFET array, degradation of the PWM driver ICs, and loss of feedback signal due to damaged encoder connections or cable insulation breakdown. Initial checks should verify that the supply voltage is within spec and that all input signals (position, velocity, torque) are present and clean; inspect the board for burn marks or swollen electrolytic capacitors, then review any error codes logged by the host controller.[oss-gpt-20b]
