The I
2
t monitoring reported by the module is given with respect to the first I
2
t monitor response
(power stage or motor), if both I
2
t monitors are activated (MP2302.x, MP2304.x). This early
warning is withdrawn as soon as the limit for reset is reached.

Error recognition:
Temperature
models
The temperature model of the motor or power module is defined by the entries in the motor
table or power module table, respectively (motor.mot, inverter.inv). Remember that calculation
of which temperature model to use depends exclusively on the availability or nonavailability of
the parameters. In addition, the parameters for motors and power modules are to be evaluated
separately.
