Parameter Descriptions
I2T INHIBIT
PREF: 161.01
Default: FALSE
Range: FALSE / TRUE
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.
I2T LIMIT MOTOR
PREF: 161.02
Default:FALSE
Range: FALSE / TRUE
This diagnostic indicates the state of the motor current protection.
FALSE:
the level of motor load is lower than 100%
TRUE :
the level of motor load is higher than 100%
I2T MOTOR LOAD
PREF: 161.03
Default: —.0 %
Range: —.0 %
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
PREF: 161.04
Default: FALSE
Range: FALSE / TRUE
This diagnostic reports on the state of the I2T motor trip:
FALSE :
the motor is running, the level of the motor load is lower than 100% (if the trip is active)
TRUE :
the drive has tripped, the level of motor load is higher than 100%
