摘要： Elevator brake or other drag is checked by establishing (10-13) baseline motor currents at plural determined positions as the car is moved up and down both empty and with full load. In a normal run (21), the load is recorded (22) and the motor current required to drive the load at rated speed at the next determined position is both predicted (28) and measured. If the difference between the predicted and actual current exceeds a tolerance (33, 34), the car stops at the next floor (35), the system is shut down (39) and a message generated (40). When the brake is in proper operating condition, baseline motor current required to move a car with the brake engaged is recorded. Thereafter, a high fraction (such as 90%) of baseline motor current is applied to attempt to move the car. If the car moves, the system is shut down (101) and a message generated (102).
摘要翻译：通过在多个确定的位置处建立（10-13）基线电动机电流来检查电梯制动或其他阻力，因为轿厢在空载和满载时上下移动。在正常运行（21）中，记录负载（22），并且预测（28）和测量在下一个确定位置以额定速度驱动负载所需的电机电流。如果预测电流和实际电流之间的差异超过容差（33,34），则轿厢停在下一层（35），系统关闭（39）并且生成消息（40）。当制动器处于正常工作状态时，记录在制动器接合时移动汽车所需的基准电机电流。此后，施加高比例（例如90％）的基准电机电流以尝试移动汽车。如果汽车移动，系统将关闭（101）并生成一条消息（102）。
