Parameter Descriptions
I2T INHIBIT
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 :
TRUE :
ENABLE
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. Warning: Changing this parameter may result in damage to the motor. Thermal
devices in the motor should be used to protect the motor.
FALSE :
TRUE :
I2T LIMIT MOTOR
This diagnostic indicates the state of the motor current protection.
FALSE:
TRUE :
I2T MOTOR LOAD
This diagnostic indicates the percentage of thermal motor load.
This value is the output of the filter based on the THERMAL TIME CST and PERM CURRENT parameters of the MOTOR
PMAC 1 Function Block. When this output exceeds 100%, the drive trips in I2T MOTOR TRIP.
MOTOR I2T TRIP
This diagnostic reports on the state of the I2T motor trip:
