Expert Q&A & Selection Guide
What does “Normal Duty 45 kW” and “Heavy Duty 37 kW” mean?
- Normal Duty means 45 kW for standard applications. Heavy Duty means 37 kW for tough jobs with frequent starts and stops. Choose based on your hardest daily use.
What can I install in the three option slots?
- You can add a feedback card for encoder input, a safety card for safe torque off, or a communication card like Ethernet/IP. This lets you customize the drive.
Does this drive need an external braking resistor?
- The braking transistor is built in. But you need to add an external resistor to handle the braking energy. Match the resistor to your motor size.
Is the IP20 enclosure enough for a dusty environment?
- IP20 protects against fingers and small objects. It is not dust-tight. For very dusty areas, install the drive in a higher-rated external cabinet.
How do I program the drive without a Human Interface Module (HIM)?
- Use Connected Components Workbench software on a PC. Connect with a USB cable. This method is common for initial setup and advanced programming.
