Module 9367 I
2
t monitoring
The module reports
an I
2
t early warning
an I
2
t error (temperature exceeded)
The I
2
t monitoring reported by the module is given with respect to the first I
2
t
monitor response (power module or motor), if both I
2
t monitors are activated
(MP_motFactorI2t, MP_ampFactorI2t).
The I
2
t early warning is withdrawn as soon as the limit for reset is reached. For
the response behavior, see "Limit values" on page 969.
Constraints:
Unconnected axes respond with all error bits as 0.
The I
2
t monitor responds if the current value exceeds 110 % of the rated
current.
The "I
2
t early warning" is set approx. 200 ms before the limit takes effect.
The "I
2
t monitoring" is set when the limit is reached.
For the spindle axis, only the I
2
t early warning is possible.
