Here are some tips to help you with an industrial AC drive start up.
Before You Start
• VFDs are mounted in an appropriate environment and required input circuit protection.
• Install all electrical conduit, if needed, prior to the AC drive start up
• The electrical in/out 3Ø power cable have been pulled and are terminated onto VFDs.
• The AC motors are mounted and are uncoupled from the load, if possible, to facilitate an auto tune of the VFD with access to the motor name plate data.
• The communication signals are pulled and are near the field connection terminals on the VFD.
