Altivar® 58 TRX AC Drives
Type H Specifications
[1]The maximum allowable input line unbalance is
5% for 460 V input line short circuit capacity of
15,000 A, 2.5% for 460 V input line short circuit capacity of 30,000 A, 0.5% for 460 V input line short circuit capacity of 65,000 A. If the resulting voltage harmonic distortion exceeds 5%, three phase line reactors are recommended.
[2]Input voltage is 460 V,
[3]See page 26 and following for available accessories and options.
[4]The drive controller can be configured to reduce switching frequency if the drive thermal state reaches 95%. When the drive thermal state returns to 70%, the switching frequency returns to the set value. If the duty cycle (drive controller run time) does not exceed 60% (36 second maximum for a 60 second cycle) derating is not required.
[5]Motor thermal protection can be set between 25 and 136% of the drive controller rating.
