*1: AC reactor (PFL): Mandatory for VFAS1-6110KPC and above.
*2: Transformer for fan supply (TRS) ⇒Refer to section 1.4.4.
*3: ⇒ Refer to Section 2.3.2 for switch functions.
*4: 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.
*5: 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.
*6: For PWR connection conforming to safety standards, refer to Section 9.3.
*7: If you use a braking unit (optional) and external braking resister (optional) in combination.
*8: TRS(Transformer for fan power supply) can not be used this system for VFAS1-6110KPC and above.
