Chap. 1 INTRODUCTION TO FRENIC-Mini
• Alarm history for up to 4 latest alarms
The inverter records detailed information for up to 4 alarms that occurred most recently, which can
also be displayed on the LED.
Refer to Chapter 3, Section 3.3.6 "Reading alarm information."
• Lifetime forecast signal via transistor output
This signal is output when the reservoir capacitor in the DC link bus, the electrolytic capacitors on the
printed circuit board, or the cooling fans have been nearing the end of their service life.
Refer to function code E20 in Chapter 9, Section 9.2.2 "E codes (Extension terminal functions)"
for details.
Interface for peripheral devices and comprehensive protective functions
• All models are equipped with an inrush current suppression circuit.
FRENIC-Mini series features an inrush current suppression circuit as standard in all models to reduce
the cost of peripheral devices such as input magnetic contactor.
• Terminals for a DC reactor (DCR) provided as standard
Terminals for connection of a DCR, which are necessary for suppressing harmonics, are provided as
standard in all models.
• Input/output phase loss protective function
FRENIC-Mini series can detect output phase loss at all times during starting and running. This feature
assists you for keeping operation of your system stable.
• Switchable sink/source
The input/output mode (sink/source) of the digital input terminals can be switched by means of an
internal jumper switch. No engineering change is required in other control devices including PLC.
• Motor can be protected by a PTC thermistor
The motor is protected by PTC (Positive Temperature Coefficient) thermistor which detects the
motor's temperature and stops the inverter before the motor is overheated.
Flexible through options
• Function code copy function
The optional remote keypad includes a built-in copy facility, so you can copy function code data set in
a source inverter and duplicate it into a destination inverter.
• Inverter support software FRENIC Loader available
The inverter support loader program (Windows-based), which simplifies the configuration of function
codes, is available as a free-of-charge option. It can be downloaded from our Website.
Refer to Chapter 5, "RUNNING THROUGH RS-485 COMMUNICATION" for details.
