Description
Load monitoring configuration (factory setting: 1)
1: Torque and load failure monitoring
2: Speed and load failure monitoring
3: Load failure monitoring
Load monitoring delay time (factory setting 10 s)
If, after the motor is switched on, the "LOW" signal is present on the associated
digital input for longer than this time, a load failure is assumed (F07936)
Load monitoring failure detection (factory setting: 1)
Interconnect the load monitoring with a digital input of your choice.
