产品详情资料

 记住，冷却是指数的，时间常数是从100%热容量到0%的总时间的五分之一。尝试根据电机上的可用数据确定保守值。有关详细信息，请参见以下示例。如果没有可用的数据，则必须进行有根据的猜测。也许可以从具有类似尺寸或用途的其他电机估算电机数据。注意，在更好地理解电机要求之前，保守保护好作为。请记住，目标是在不妨碍所需工作负载的情况下保护电机。C、 1.2示例电机数据表表明，允许的启动顺序为2冷或1热，之后必须等待5小时才能尝试再次启动。•这意味着在正常启动条件下，电机使用的热容量介于34%和50%之间。因此，允许连续启动两次，但不能连续启动三次。•如果热/冷曲线或热/冷安全失速比不可用，则将0.5（1热/2冷启动）编程为热/冷比。•编程启动抑制“开启”可在热容量可用时立即重新启动。
Remember that the cooling is exponential and the time constants are one fifth the total time to go from 100% thermal capacity used to 0%. Attempt to determine a conservative value from available data on the motor. See the following example for details. If no data is available an educated guess must be made. Perhaps the motor data could be estimated from other motors of a similar size or use. Note that conservative protection is better as a first choice until a better understanding of the motor requirements is developed. Remember that the goal is to protect the motor without impeding the operating duty that is desired. C.1.2 EXAMPLE Motor data sheets state that the starting sequence allowed is 2 cold or 1 hot after which you must wait 5 hours before attempting another start. • This implies that under a normal start condition the motor is using between 34 and 50% thermal capacity. Hence, two consecutive starts are allowed, but not three. • If the hot and cold curves or a hot/cold safe stall ratio are not available program 0.5 (1 hot / 2 cold starts) in as the hot/cold ratio. • Programming Start Inhibit ‘On’ makes a restart possible as soon as thermal capacity is available.
