1.负载类型和变频器的选择：变频器不是在任何情况下都能正常使用，因此用户有必要对负载、环境要求和变频器有更多了解,电动机所带动的负载不一样，对变频器的要求也不一样。
A:风机和水泵是普通的负载：对变频器的要求为简单，只要变频器容量等于电动机容量即可（空压机、深水泵、泥沙泵、快速变化的音乐喷泉需加大容量）。
B:起重机类负载：这类负载的特点是启动时冲击很大，因此要求变频器有余量。同时，在重物下放肘，会有能量回馈，因此要使用制动单元或采用共用母线方式。
C:不均行负载：有的负载有时轻，有时重，此时应按照重负载的情况来选择变频器容量，例如轧钢机机械、粉碎机械、搅拌机等。
D:大惯性负载：如离心机、冲床、水泥厂的旋转窑，此类负载惯性很大，因此启动时可能会振荡，电动机减速时有能量回馈。应该用容量稍大的变频器来加快启动，避免振荡。配合制动单元回馈电能。
