*1. The enclosure rating complies with JISC0920.
*2. If you must use the motor at higher than 50/60 Hz, check the allowable maximum motor speed and other
information with the motor manufacturer.
*3. In the HND/ND (light load) mode or PM motor mode compared with the HHD/HD (heavy load) mode, for
some parameters, the default data and setting range also differ. For details, refer to 6-2-2 Load Mode Selec-
tion on page 6-10.
*4. By default, the maximum frequency is adjusted to 10 V for a voltage input of 0 to 10 VDC. If necessary,
adjust the default parameter settings. For details, refer to 8-3-2 Analog Input Adjustment Function on page
8-34.
*5. Derating of the rated output current of the inverter may be required depending on the heavy/light load mode
selection, operating ambient temperature, side-by-side installation, and carrier frequency settings.
Use the inverter in an appropriate environment according to A-7 Derating Table on page A-287.

*1. In FreeRun mode, slaves perform I/O processing, i.e., refresh I/O data asynchronously with the communica-
tions cycle of the master. The communications cycle is determined by the cycle time of the master. For the
communications response time of the EtherCAT Communication Unit, refer to A-6 Communications Re-
sponse Time on page A-286.
