Error code R002 on a PowerFlex 525 drive signifies a 'Regen Overvoltage Fault'. This happens when the DC bus voltage rises above its safe operating limit, often during deceleration. This can be caused by high inertia loads or situations where the drive regenerates a significant amount of power. Consider using a dynamic braking resistor or adjusting deceleration ramp times.
