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)
