Chapter 6. Function Description (I/O)
2) I/O_46 (Fault Output Relay (30A, 30B, 30C))
This function can be used when the inverter fault signal is generated through the relay contact. the fault alarm is
triggered differently by setting the bits related to the low voltage trip, inverter trip and the number of retry.

3) I/O_59 ~ 61 (Overload trip enable, level, time)
If the inverter output current higher than the overload limit level is kept for the overload limit time, the inverter
blocks the gating of IGBTs and issues the trip message.
