*1: AC reactor (PFL): Mandatory for VFAS1-6110KPC and above.
*2: Transformer for fan supply (TRS) ⇒Refer to section 1.4.4.
*3: Every model with a capacity of 160kW or less come with dynamic braking unit drive circuits (GTR7) built into them as
standard equipment, so if your inverter is among these models, connect an external braking resistor (optional) alone.
*4: If you are using a 200kW model or larger, use a braking unit (optional) and an external braking resistor (optional) in
combination.
*5: ⇒ Refer to Section 2.3.2 for switch functions.
*6: The functions assigned to terminals OUT1, VI/II and RR/S4 can be switched by changing parameter settings.
⇒ For details refer to Section 2.3.2.
*7: To supply control power from an external power supply for backing up the control power supplied from the inverter, an
optional control power backup device (CPS002Z) is required. In such a case, the backup device is used at the same time
with the internal power supply of the inverter.
To back up control power, set the parameter (Control power supply backup option failure monitoring) properly.
⇒ For more information, refer to 6.33.24.
*8: For PWR connection conforming to safety standards, refer to Section 9.3.
*9: TRS(Transformer for fan power supply) can not be used this system for VFAS1-6110KPC and above.
