‹ Drive Derating Data
„ Carrier Frequency Derating
The drive can be operated at above the default carrier frequency by derating the drive capacity.
„ Temperature Derating
To ensure the maximum performance life, the drive output current must be derated as shown in Figure 24 when the drive
is installed in areas with high ambient temperature or if drives are mounted side-by-side in a cabinet. In order to ensure
reliable drive overload protection, set parameters L8-12 and L8-35 according to the installation conditions.
Parameter Settings
IP00 Enclosure
Drive operation between -10 °C and 50 °C allows 100% continuous current without derating.
IP00 Enclosure with Top Protective Cover
Drive operation between -10 °C and 40 °C allows 100% continuous current without derating. Operation between 40 °C
and 50 °C requires output current derating.

<1> The accuracy of these values depends on motor characteristics, ambient conditions, and drive settings. Specifications may vary with different
motors and with changing motor temperature. Contact Yaskawa for consultation.
<2> Overload protection may be triggered when operating with 133% of the rated output current if the output speed is less than 6 Hz.
<3> Ground protection cannot be provided when the impedance of the ground fault path is too low, or when the drive is powered up while a ground
fault is present at the output.
NOTICE
Refer to the L1000E Quick Start Guide TOEPYAIL1E01 or Technical Manual SIEPYAIL1E01 for more information
regarding the Carrier Frequency Derating and for complete product instructions necessary for proper installation, set
up, troubleshooting and maintenance. The L1000E Series CD-ROM No. CD.L1E.01 packaged with the drive contains
the L1000E Technical Manual No. SIEPYAIL1E01 and additional L1000E Series manuals.
