Check the following about connection:
● Wiring is performed correctly.
● Appropriate power supply voltage is applied.
● The phase sequence is correct.
When the phase sequence is correct, check for the short circuit across terminals
SOF and SD and across terminals RES and SD.
Check the following about connection:
● Connection is performed correctly.
● Wiring for the main circuit terminals R/L1, S/L2, and T/L3 on the inverter is performed
correctly.
● The inrush current limit resistor is not damaged.
Check the following about connection:
● Connection is performed correctly.
● Wiring for the main circuit terminals R2/L12, S2/L22, and T2/L32 on the converter is
performed correctly.
Check the following about the setting:
● The parameter settings in the inverter are appropriate. (Setting method differs by the
inverter series.)
Check the following about connection:
● Wiring is performed correctly.
● Appropriate power supply voltage is applied.
● The phase sequence is correct.
Identify the cause of the trip and remove it before turning ON the power of the breaker.
It is not a fault if noise comes from the dedicated reactor during regenerative driving of the
converter (in other words, it is a fault if noise comes despite the stop state of the converter
by the Converter stop (SOF) signal).
If needed, devise methods of reducing noise by modifying the enclosure in which the
reactor is installed.
