* In case of =2 setting, be sure to install the input AC reactor (ACL) between power supply and inverter,
6
to remove the protective label on the top of the inverter, and to connect the grounding capacitors by pressing
the grounding capacitor switch.
Then, to use the inverter at 40°C or less of the ambient temperature with setting f300 to 4.0 kHz or less.
* If parameter f316=0, 2 or 4 and current is increased to main module overheat level (ol3) or to
overheat level (oh), the l alarm or h alarm occurs. If the cumulative amount of overload is increased further,
ol3 trip or oh trip occurs.
In this case, to avoid such trips, reduce the stall prevention level (f601) properly.
* PWM carrier frequency is increased at high output frequency area for stable operation, even if f300 is set
to low PWM carrier frequency.
