Monitor P-N Voltage (Internal DC Voltage)
How to see the movement of the voltage between P and N terminal (internal DC voltage) of the
Q
inverter?
How to monitor the voltage between P and N terminal (internal DC voltage) when the motor is in
regenerative state?
DC bus voltage monitor [d102]
A
Displays the DC voltage (DC voltage between P and N on the inverter main circuit terminal
block) charged in the main circuit capacitor of the inverter.
During running, the monitor value also fluctuates according to the actual inverter DC voltage.
The voltage between P-N is DC voltage. If the voltage between P and N exceeds approx. 400
!
VDC (200 V class)/ approx. 800 VDC (400 V class), "Overvoltage error [E07]" occurs.
See "15.2 Troubleshooting for Protection Functions Related Error" for more information about
troubleshooting when [E07] occurs.
