Q VFPS1-4300PLE~4900PLE
A switch or switches enable to reduce grounding capacitance.
Q VFPS1-4007PDE~4220PDE
There is no switch.
Q VFPS1-4300PDE~4900PDE
A switch enables to reduce grounding capacitance.
1.3.4 In case of adopting external braking resistor (Optional)
To wire for external braking resistor, an attention is needed because PA/+ terminal have a wiring to the internal DC
reactor. Refer to followings when you wire for external braking resistor.
Q0.75~22kW
With reference of the figure right, make the each
solderless terminal in back to back and fasten
them with the screw.
Q30~90kW
Fasten with the screw both of copper bar connected to the PA/+ terminal and the stripped cable for external braking
resistor.
To change the capacitance
