6.7.6 Monitoring the driven load
In many applications, the speed and the torque of the motor can be used to determine whether
the driven load is in an impermissible operating state. The use of an appropriate monitoring
function in the converter prevents failures and damage to the machine or plant.
Examples:
● For fans, an excessively low torque indicates a torn drive belt.
● For pumps, insufficient torque can indicate a leakage or dry-running.
● The motor can be blocked by an excessively high torque at a low speed.
