Lenze i410 - Heavy Load Monitoring

9.5.7 Heavy load monitoring
If the apparent current of the motor exceeds a dened threshold value due to a heavy duty
s
tate, a congurable error is triggered (incl. logbook entry).
Condions
Monitoring is acvated as soon as the motor is running. Monitoring can be deacvated with
the seng "No response".

Details
Exceedance of the dened threshold:
•
If the actual appar
ent current exceeds the congured threshold value, the delay me
encoder is started.
•
If the actual appar
ent motor current falls below the threshold value minus 5% (hysteresis -
not adjustable), the delay me encoder is set to zero.
Independent of the error response, the output signal (Heavy duty monitoring [84]) is
triggered:
•
If the actual appar
ent current of the motor exceeds the threshold for longer than the delay
me, the output signal is set to TRUE.
•
If the actual appar
ent current of the motor falls below the threshold value minus 5%
(hysteresis), the output signal is set to FALSE.
•
If the delay me is set to 0 seconds, the output signal is immediately set to TRUE.
The error response is acvated according to its sengs:
•
If the actual appar
ent current of the motor exceeds the threshold value for longer than the
congured delay me, the selected error response is acvated.
•
When the error response is triggered, an entry is generated in the logbook (excepon:
Error response - Selecon [0]). 465337 ^ 306
