热过载保护（TOL）热过载保护是通过对电动机运行中热容量的跟踪计算来保护电动机免于因过热而缩短寿命或损坏。同时，热过载保护的热记忆功能对需要频繁启动电机的场合具有重要的意义。热过载保护具有热记忆功能，可以有效地保护马达过热状态下重复起动。M101/M102装置模拟了电机在各种运行状态下的热状态，以便大限度地使用电机，又能保证电机的安全。热过载保护同时考虑了电机转子和定子的温升，并充分考虑了三相不平衡对电机发热的影响。当要重新起动马达时，装置会自动判断马达停止运行后的温度是否已下降到可以重新起动的限值，是则允许重新起动马达，否则闭锁起动操作直至电机温度下降到满足重新起动的限定条件。M102-MwithMD2124VDCM102-MwithMD3124VDCM102-PwithMD2124VDCM102-PwithMD3124VDCM102-MwithMD21110VACM102-MwithMD21240VACM102-MwithMD31110VACM102-MwithMD31240VACM102-PwithMD21110VACM102-PwithMD21240VACM102-PwithMD31110VACM102-PwithMD31240VACM102-P2.5-5.0withMD2M102-P12.5-30.0withMD2M102-P12.5-30.0Aw/MD224VDCM102-P30.0-63.0Aw/MD224VDCM101-MwithMD2124VDCM101-MwithMD3124VDCM101-PwithMD2124VDCM101-PwithMD3124VDCM101-MwithMD21110VACM101-MwithMD21240VACM101-MwithMD31110VACM101-MwithMD31240VACM101-PwithMD21110VACM101-PwithMD21240VACM101-PwithMD31110VACM101-PwithMD31240VACM101-P1.0-2.5withMD2M101-P5.0-12.5withMD2M101-P12.5-30.0withMD2M101-P30.0-63.0withMD2M101-M24VDCwithoutMD&1.2McableM101-P24VDCwithoutMD&1.2Mcable)
