Drive Derating Data - YASKAWA L1000A Technical Manual

A.6 Drive Derating Data
The drive can be operated at above the rated temperature, altitude, and default carrier frequency by derating the drive
capacity.
◆ Rated Current Depending on Carrier Frequency
Table A.7 shows the drive output current depending on the carrier frequency settings.
The 2 kHz value is equal to the Normal Duty rated current. If the carrier frequency is increased above 2 kHz in ND, the
rated output current is reduced.
The 8 kHz and 5 kHz values are equal to the Heavy Duty rated current. They define the value up to which the carrier
frequency can be increased in HD without a current derating (default HD carrier frequency is 2 kHz). Increasing the
carrier frequency above 8 kHz or 5 kHz reduces the rated output current.
Use the data in Table A.7 to linearly calculate output current values for carrier frequencies not listed in the tables.
