In case of =2 setting, be sure to install the input AC reactor (ACL) between power supply and inverter
*
and use at ambient temperature 40°C or less. Set f300 to 4.0 kHz or less.
If parameter f316=0 or 2 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.
If parameter f316= 2 or 3, setting parameter f300 to 4.0kHz or less is recommended. Output voltage
*
may be reduced.
PWM carrier frequency is increased at high output frequency area for stable operation, even if f300 is set
*
to low PWM carrier frequency.
In case of three phase 500V-4.0kW model with aul= 2 setting, be sure to press the grounding capacitor
*
switch and connect the grounding capacitor to the ground.
