Figure 7-25 Load failure monitoring using a digital input
Parameter Description
p2192 Load monitoring delay time (factory setting 10 s)
After the motor is switched on, if the "LOW" signal is present at the associated
digital input for longer than this time, the inverter signals a load failure (F07936).
p2193 = 1…3 Load monitoring configuration (factory setting: 1)
0: Monitoring is deactivated
1: Torque monitoring (see Load monitoring (Page 395)) and load failure
2: Speed deviation monitoring (see below) and load failure
3: Load failure monitoring
p3232 = 722.x Load monitoring failure detection (factory setting: 1)
Interconnect the load monitoring with a digital input of your choice.
For more information, see the List Manual (the parameter list and function diagram 8013).
7.7.10 Real time clock (RTC)
The real-time clock (RTC) is the basis for time-dependent process controls, e.g.:
● To reduce the temperature of a heating control during the night
● Increase the pressure of a water supply at certain times during the day
Real-time clock: Format and commissioning
The real-time clock starts as soon as the Control Unit power supply is switched on for the
first time. The real-time clock comprises the time in 24-hour format and the date in "day,
month, year" format.
After a Control Unit power supply interruption, the real-time clock continues to run for approx.
five days.
