Parameter Descriptions
I2T INHIBIT
PREF: 161.01
Default: FALSE

This parameter enables/disables the I2T trip action. The drive continues to look for the motor load, but does not trip if the
level is higher than 100%:
FALSE :
I2T trip is enabled
TRUE :
I2T trip is disabled.
ENABLE
PREF: 161.05
Default:TRUE
Range: FALSE / TRUE
This parameter disables this function block. Thus the I2T trip and the drive no longer limits motor current. This parameter is
available in firmware version 3.9 or higher.
