Installation & Maintenance Best Practices

To get the best performance and lifespan from your R7 series servo drives, follow these key guidelines:

Handling and Installation

• Max shock tolerance: 98 m/s² handle carefully to avoid bearing or shaft damage

• Use proper tools (e.g., pulley removers) when mounting/removing couplings

• Maintain 100 mm spacing for airflow and ventilation

Environmental Requirements

• Operating Temp: 0–40°C (AP08H up to 55°C)

• Humidity: Max 85–90% RH, no condensation

• IP Rating: IP65 (except shaft/cable outlets)

• Avoid corrosive gases, vibration zones, or poor ventilation

Operational Safety

• Mount with the nameplate facing outward

• Keep units clean during installation protect from metal debris or oil

• Ensure loads and torques are within rated values to avoid mechanical fatigue

Proper handling ensures maximum accuracy and drive life across all models.
