The following signals are available for the ”i
2
t power module limit” func-
tion:
Output terminal signal
––> function number 37
(power module current not limited)
PROFIBUS status signal
––> MeldW.10
(power module current not limited)
The following parameters are available for the ”i
2
t power module limi-
ting” function:
Parameters which have to be set:
– P1260
i2t limiting, limit current power module S6
– P1261
i2t limiting, rated power module current
These parameters are preset to protect the power module. It
may be possible to protect the motor against continuous over-
load by reducing the parameter values.
Parameters used for diagnostics:
– P1262
i2t time in limiting
– P1263
actual i2t limit factor
– P1264
i2t actual utilization factor (from SW 4.1)
