VII. Common Alarm Codes & Fehlerbehebung

1. RH4: Surge suppression circuit fault → Frequent power cycling, damaged main circuit charging relay/diode; power off and cool down before inspecting power board
2. HV: Overvoltage → Excessive regenerative energy during deceleration (install external braking resistor); input voltage out of specification
3. LV: Undervoltage → Missing main power phase, excessive voltage drop on input cables, poor contact of contactor terminals
4. Et/EC: Encoder fault → Broken encoder cable, loose connector, damaged encoder
5. OC1/OC2: Output overcurrent → Short circuit on motor U/V/W terminals, power cable grounding fault, damaged drive IGBT module
6. AH: Drive overheating → Blocked cooling fan, poor cabinet ventilation, long-term overload operation

VIII. Typische Anwendungsszenarien

Feed axes of CNC machine tools, Graviermaschinen, Laserschneidmaschinen

Packaging equipment: Labelers, Schneidemaschinen, positioning conveyor axes

Automatisierte Produktionslinien, manipulator joints, warehousing stacking positioning

Precision feeding equipment for textile and printing industries

1. Key Selection Pitfalls to Avoid
2. VV2 only supports incremental encoders. Select VV3 model if absolute origin memory after power-off is required;
3. External braking resistor is mandatory for frequent forward/reverse operation and high-inertia loads to prevent HV overvoltage alarms;
4. Single-phase 220V power supply delivers 20% lower load capacity than three-phase input; three-phase power is preferred for heavy-duty applications;
5. Models with -ZC1 suffix must be purchased for fieldbus communication with PLCs; standard VV2 has no RS485 interface.

Full Practical Application Cases of Fuji RYH152F5-VV2 (1.5kW ALPHA5 Smart Pulse-Type Servo)

This drive is a differential pulse command version equipped with a 2500-line incremental encoder, compatible with medium-inertia GYB152D5 and low-inertia GYS152D5 motors. It is ideal for medium-load, high-precision positioning applications and low-rigidity mechanical structures such as gear racks and belt drives. Below are mass-production cases covering six major industries, including equipment process, servo configuration, selection advantages and debugging tips.
