5.3 Description of Function Codes 5.3.2 E codes (Extension terminal functions)
Low DC link bus voltage detection “U-EDC” assignment (Function code data = 77)
This output signal comes ON when the DC intermediate voltage drops below E76 (DC link bus low-voltage detection
level), and it goes OFF when the DC intermediate voltage exceeds E76.
( Function code E76)
During decelerating at momentary power failure “IPF2” assignment (Function code data = 79)
When F14 is 2 or 3, signal turns ON when the intermediate DC voltage will drop to or below the H15 “continue to
run level”, and the motor continues to run. The signal turns OFF after power has been restored, and the intermediate
DC voltage reaches the “voltage set at H15 + 10 V or more”.
Even when F14 data is set to 4 or 5, the signal comes ON when the DC intermediate voltage drops below the
undervoltage level, and it goes OFF when the DC intermediate voltage becomes “at least 10 V higher than the
undervoltage level.”
( Function codes F14, H15)
Positioning completed “PSET” assignment (Function code data = 82)
This output signal comes ON as a positioning completion signal. This signal is used when in-position with the
position control function, and when settling is complete with servo lock function.
Refer to function codes J97 to J99 for details on the servo lock function. Refer to d201 to d299 for details on
the position control function.
Maintenance timer counted up “MNT” assignment (Function code data = 84)
Once the inverter’s cumulative run time or the startup times for the motor 1 exceeds the previously specified count,
this output signal comes ON.
( Function codes H78, H79)
Frequency arrival AND frequency detected “FARFDT” assignment (Function code data = 87)
The FARFDT, which is an AND composite signal of FAR and FDT, comes ON when both signal conditions are met.
( Function codes E30 to E32)
Magnetic pole position detection signal “PTD” assignment (Function code data = 89)
An ON signal is output if the magnetic pole position is detected when a PM motor starts running.
