For system-level compatibility verification, share your existing BOM or control panel schematic with our technical team.
Selection Guide
Use the following criteria to confirm the 9500-8201A is the right drive for your application:
- Step 1 – Power Rating: Match drive continuous and peak current to motor nameplate data
- Step 2 – Feedback Type: Confirm encoder/resolver interface (incremental, absolute, SinCos)
- Step 3 – Bus Voltage: Verify AC input voltage range matches your panel supply
- Step 4 – Communication: Confirm fieldbus protocol matches your PLC/controller
- Step 5 – Environment: Check IP rating, ambient temperature, and derating requirements
- Step 6 – Certifications: Confirm CE/UL marks meet your regional compliance requirements
Not sure? Contact our engineers with your motor nameplate data and we’ll recommend the correct drive.
