The Effect Of Carrier Frequency [C6-03] Adjustment On Output Current - YASKAWA CIMR-LE2A0018DAC Manual De Instrucciones

1 Selecting an L1000E AC Drive for Elevator Applications

Drive Nameplate Output Current
The L1000E nameplate current is the output current that the L1000E can supply at the default carrier frequency for a
maximum run of 180 seconds and a motor electrical frequency above 6.0 Hz operating 50% of the time. Increasing the
Carrier Frequency [C6-03] or operating below 6.0 Hz will reduce the allowable output current and available motor torque.


The Effect of Carrier Frequency [C6-03] Adjustment on Output Current

Table 1 lists constant-speed output amps for L1000E models adjusted for carrier frequencies common to elevator
applications. Select a higher Carrier Frequency [C6-03] to reduce audible motor noise when required by the application.
Selecting a lower carrier frequency or a larger L1000E model, does not always result in increased current capacity.
