9 Apollo Motor Overload Protection
The Apollo Control System provides two types of motor overload protection.
•
I2T Motor Overload
– The I2T overload algorithm protects the motor from heat damage by modeling the heat
buildup in the motor. The parameters for setting up the I2T overload are shown in

•
Fixed Threshold/Time Delay Overload
– The fixed threshold overload algorithm is referred to as Motor
OverCurrent in the Apollo system and protects the motor from heat damage by monitoring motor current using a
simple thresholding algorithm. The parameters for setting up the overcurrent protection are accessible by selecting
Motor OverCurrent in
