18.5 Lenze motor
18.5.1 Utilisation >100 %, regarding the effective torque
18.5.2 Max. motor speed is higher than the permissible motor speed
18.5.3 Max. motor torque is higher than the permissible motor torque
Warning!
The utilisation of the motor relative to the effective torque is xxx %. Thus the limit value of 100 % is ex-
ceeded.
Cause Effects Possible remedies
The calculated effective torque of the
application on the motor is higher
than the permissible torque.
The motor is thermally overloaded. • Select different motor.
• Select a higher ratio if the speed
range of the motor is badly uti-
lised.
Warning!
The max. occurring motor speed is xxx rpm. Thus the max. permissible motor speed of yyy rpm is exceed-
ed.
Cause Effects Possible remedies
The maximum speed that occurs is
higher than the maximum permissi-
ble speed of the motor.
The motor is mechanically destroyed! • Reduce gearbox ratio or speed.
• Select motor with a higher per-
missible speed.
Warning!
The maximum permitted torque of the motor is exceeded. The motor might get damaged!
Cause Effects Possible remedies
For servo motors, the maximum per-
missible torque may not be exceed-
ed. This limit is compared to the
occurring max. torque (absolute val-
ue).
The motor is mechanically/electrical-
ly overloaded.
• Select bigger motor.
• If required, reduce load.
• If the use of a gearbox is intend-
ed, the torque can be reduced
by a greater ratio.
