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)
Interrelationship between parameters:
P1262 Constant Running
P1263 100 % <100 %
P1264 <100 % 100 %
––> Limiting? No Yes
