t Current [232]
Sets the current limit for the motor I
2
t protection.
Communication information
Motor I
2
t Time [233]
Sets the time of the I
2
t function. After this time the limit for
the
I
2
t is reached if operating with 120% of the I
2
t current
value. Valid when start from 0 rpm.
Communication information
Fig. 79 I
2
t function
Fig. 79 shows how the function integrates the square of the
motor current according to the “Mot I
2
t Curr [232]” and
the “Mot I
2
t Time [233]”.
When the selection Trip is set in menu [231] the AC drive
trips if this limit is exceeded.
When the selection Limit is set in menu [231] the AC drive
reduces the torque if the integrated value is 95% or closer to
the limit, so that the limit cannot be exceeded.
