5.4 Details of Function Codes
5-148
Assignment of lifetime alarm LIFE (Function code data = 30)
This function outputs an ON signal when it is judged that the service life of any one of capacitors (DC link
bus capacitors and electrolytic capacitors on the printed circuit boards) and cooling fan has expired. This
signal should be used as a guide for replacement. If this signal is output, use the specified maintenance
procedure to check the service life of the parts and determine whether the parts should be replaced or not.
(
Function code H42)
This output signal turns on when the locking status of the internal air circulation DC fan (45 kW or above for
200 V class series, 75 W or above for 400 V class series) has been detected.
Assignment of reference loss detected REF OFF (Function code data = 33)
This function outputs an ON signal when an analog input is used as a frequency command source, and
when the broken wire of the analog input (reference loss) is detected. This signal turns off when the normal
operation under the regular frequency reference is resumed.
(
Function code E65)
Assignment of Overload prevention control operating OLP (Function code data = 36)
This function outputs an ON signal when overload prevention control is activated. (The minimum output
signal range: 100 ms)
(
Function code H70)
Assignment of Current detect ID Current detect 2 ID2, and Current detected 3 ID3 (Function code data =
37, 38, 39)
When the inverter output current is same or above the set level of the current detect (operation level) and
when the current detect (timer) continues same or longer than the set time, this function outputs the ON
signal. (The minimum output signal range: 100 ms)
(
Function code E34)
Assignment of Low current detected IDL (Function code data = 41)
This function outputs an ON signal when the output current of the inverter decreases below the set level of
the current detection (operation level) or lower, when the current detect (timer) continues longer than the set
time. (The minimum output signal range: 100 ms)
(
Function code E34)
Assignment of PID alarm output PID-ALM (Function code data = 42)
This function can output absolute value alarm and deviation alarm as the PID alarm.
