Motor Electronic Thermal Warning
Use this function to output a warning signal before the motor electronic thermal function executes an
overload protection. The electronic thermal warning operates at or above the current value set in the
Overload early warning 2 Level (OL2) (3005Hex-23Hex). Generally, set to around 80% to 90% of the
current value of the Motor Electronic Thermal Level (3004Hex-0CHex/3009Hex-08Hex). The tempera-
ture characteristics of the motor are set in Motor Electronic Thermal Characteristic Selection
(3004Hex-0BHex/3009Hex-07Hex) or Motor Electronic Thermal Time Constant (3004Hex-0DHex/
3009Hex-09Hex).
Parameter No.
