GPD515/G5 OV Suppression Software Option Manual

This document describes a Yaskawa GPD515/G5 inverter software option (part number CIMR-G5MXXXXXF-017) designed to control regeneration and DC bus overvoltage in applications where the motor is overhauled by stored energy, such as flywheel and cam clutch systems. It details the acceleration and deceleration OVP (Over-Voltage Protection) control logic, including parameters for DC bus filtering, deadband, gain, and deceleration rate adjustments to manage regenerative energy.
