Rotation Monitoring - Siemens Sinamics G110M Operating Instructions Manual

If the motor current for the time p2180 lies below the current level p2179, the inverter signals
"output load not available" and alarm A07929.

Rotation monitoring

The inverter monitors the speed or velocity of a machine component via an electromechanic
or electronic encoder, e.g. a proximity switch. Examples of how the function can be used:
● Gearbox monitoring for traction drives and hoisting gear
● Drive belt monitoring for fans and conveyor belts
● Blocking protection for pumps and conveyor belts
The inverter checks whether the encoder consistently supplies a 24 V signal during motor
operation. If the encoder signal fails for time p2192, the inverter signals fault F07936.

Description
Actual current value [A]
[0] = Unsmoothed
[1] = Smoothed with p0045
Output load detection current limit (Factory setting: 0 A)
p2179 = 0: No load detection deactivated
Output load detection delay time (factory setting: 2000 ms)
Status word, monitoring functions 1
r2197.11 = 1: Output load not available
Function plan and time response of the speed monitoring
Description
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).
Load monitoring configuration (factory setting: 1)
0: Monitoring switched off
1: Monitoring torque and load drop
2: Monitoring speed and load drop
3: Load failure monitoring
Load monitoring failure detection (factory setting: 1)
Connect the load monitoring to a DI x digital input of your choice. p3232 = 722.x
