                                                                 产品详情资料：

t=时间（单位：分钟）τ=冷却时间常数（运行或停止）Ieq=等效电机加热电流过载_pickup=过载拾取设定值（FLA热/冷=热/冷曲线比率的倍数）电机制造商可提供热/冷电机的热极限信息。如果编程了热/冷曲线比率设定值，469热模型将适应这些条件。该设定值规定了继电器在电流水平低于过载拾取水平时所使用的热容量水平。当电机以低于过载拾取水平的水平运行时，所用热容量寄存器将上升或下降至基于平均相电流和热/冷曲线比率设定值的值。所用热容量将以每分钟5%的固定速率上升，或根据运行冷却时间常数下降。

                         产品英文详情资料：

t = time in minutes τ = Cool Time Constant (running or stopped) Ieq = equivalent motor heating current overload_pickup= overload pickup setpoint as a multiple of FLA hot / cold = hot/cold curve ratio The motor manufacturer may provide thermal limit information for a hot/cold motor. The 469 thermal model adapts for these conditions if the HOT/COLD CURVE RATIO setpoint is programmed. This setpoint value dictates the level of thermal capacity used the relay will settle at for current levels below the OVERLOAD PICKUP LEVEL. When the motor is running at a level that is below the OVERLOAD PICKUP LEVEL, the THERMAL CAPACITY USED register will rise or fall to a value based on the average phase current and the HOT/COLD CURVE RATIO setpoint. The THERMAL CAPACITY USED will either rise at a fixed rate of 5% per minute or fall as dictated by the running cool time constant.
