Chap. 9 FUNCTION CODES
Service life alarm -- LIFE
(Function code data = 30)
This output signal comes ON 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 of the capacitors and cooling fan. If this
signal comes ON, use the specified maintenance procedure to check the service life of these
parts and determine whether the parts should be replaced or not.
For detail, refer to the FRENIC-Mini Instruction Manual (INR-SI47-1729-E), Chapter 7
"MAINTENANCE AND INSPECTION."
Consumable part Judgment criteria of life forecasting
DC link bus capacitor 85.0% or below of the initial capacitance at shipment
Electrolytic capacitors on printed
circuit boards
Exceeding 87,000 hours of cumulative run time
(Estimated at an inverter ambient temperature of 40°C
and load factor of 80%)
Cooling fan
Exceeding 87,000 hours of cumulative run time
(Estimated at an inverter ambient temperature of 40°C
and load factor of 80%)
Inverter running 2 -- RUN2
(Function code data = 35)
This signal acts in the same way as RUN (Function code data = 0) except that RUN2 is ON
even when the DC braking is in operation.
Overload prevention control -- OLP
(Function code data = 36)
This output signal comes ON when overload prevention control is activated. The minimum
ON-duration is 100 ms. (Refer to the description of H70.)
Current detected and Current detected 2 -- ID and ID2
(Function code data = 37, 38)
The ID or ID2 output signal comes ON when the output current of the inverter exceeds the
level specified by E34 (Current detection (Level)) or E37 (Current detection 2 (Level)) and
stays above that level for the period longer than the one specified by E35 (Current detection
(Timer)) or E38 (Current detection 2 (Timer)), respectively. The minimum ON-duration is
100 ms.
The ID or ID2 goes OFF when the output current drops below 90% of the rated operation
level.
These two output signals can be assigned to two different digital output terminals
independently if necessary.
Function code E34 is effective for not only the operation level of the curren
detection ID but also the motor overload early warning OL. (Refer to the
description of E34.)
Low current detected -- IDL
(Function code data = 41)
This output signal comes ON when the inverter output current drops below the low current
detection level (E34) and it remains at the low level for the timer period (E35). When the
output current exceeds the current detection level (E37) by 5% or more of the inverter rated
current, this signal goes OFF. The minimum ON-duration is 100 ms. (Refer to the description
of E34.)
