The figure below shows an example of typical wiring in the main circuit VFPS1-6500KPC to 6630KPC inverter.
*1: AC reactor (PFL): Mandatory for VFPS1-6110KPC 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

with the internal power supply of the inverter.
To back up control power, set the parameter
⇒ 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 and external braking resister in combination.
*8: TRS(Transformer for fan power supply) can not be used this system for VFPS1-6110KPC and above.
(Control power supply backup option failure monitoring) properly.
