34. Faults 1 7 Thermal Overload Protection The Soft Starter plays an important role in the protection of your motor in that it monitors the motor for excessive thermal conditions due to starting running and ambient conditions The soft starter has a Dynamic Thermal Register system in the CPU that provides a mathematical representation of the thermal condition of the motor This thermal information is retained in memory and is monitored for excesses in both value and rate of change Inputs are derived from current values imbalances and optional RTD measurements making it dynamic to all processes involving the motor The Soft Starter monitors these conditions separately during the Start and Run modes to provide proper thermal protection at all times 1 7 1 Start Mode overload protection is selectable using one of three methods e Basic Protection 121 data is accumulated and plotted based on an Overload Curve selected in programming This is programmed per NEMA Class 5 30 standard curves and is based on the Locked Rotor Current from the motor nameplate as programmed into the Soft Starter Measured Start Capacity The user enters a measured amount of thermal capacity from a pre selected successful start as a set point to the Thermal Register for the soft starter to follow Learned Curve Protection The user sets the soft starter to the LEARN mode and starts the motor under normal starting conditions The CPU then samples and records
