CIMR-G7 Control Board Replacement Procedure

This document provides the recommended procedure for replacing a control board in large capacity CIMR-G7 drives (models 4055 to 4300, revision B or later). It emphasizes the critical need to set On-Delay Compensation parameters (n9-47 through n9-52) using the Shipping Adjustment Auto-tuning function, as replacement boards contain null values that must be calibrated to match the drive's IGBT configuration.
