7.7.8 Free technology controllers
Additional technology controllers
The inverter has 3 additional technology controllers in the following parameter ranges:
● p11000 … p11099: free technology controller 0
● p11100 … p11199: free technology controller 1
● p11200 … p11299: free technology controller 2
For more information, refer to the parameter descriptions and the function block diagram
7030 in the List Manual.
7.7.9 System protection
In many applications, monitoring the motor speed and torque provides information about the
plant or system status. By setting the appropriate responses in the case of faults, failures
and damage to the plant or system can be avoided.
Examples:
● For fans or conveyor belts, an excessively low torque can mean a broken drive belt.
● For pumps, an excessively low torque down to zero speed can mean an inadmissible
operating state.
● For extruders and mixers, excessively high torque can mean overload or a blocked
system.
System protection functions
The inverter offers the following options of monitoring the motor load torque and speed:
● No-load monitoring
● Blocking protection
● Stall protection
● Load monitoring
● Load failure monitoring
