Simple operation and wiring
Frequency setting potentiometer is
standard equipment.
The frequency can be adjusted easily by hand.
A menu mode is included in the keypad.
A long-life cooling fan is included.
Cumulative running time is recorded and displayed.
The inverter records and displays the cumulative running time
(lifetime) of the inverter itself, PCB, and cooling fan.
Input/output phase loss protective function
It is possible to detect output phase loss at all times during
starting and operation.
Sink/Source can be switched.
The input/output mode (Sink/Source) of the digital input terminals
can be switched by means of an internal jumper switch.
The motor can be protected by a PTC thermistor.
In addition to the protection by an electronic thermal relay, the
The control circuit terminal block cover
and main circuit terminal block cover
can be quickly removed.
Maintenance
Interface for peripheral devices and comprehensive protective functions
Control circuit terminal block cover
Main circuit terminal block cover
All types of data can be displayed on
the keypad.
The output frequency, set frequency, load shaft speed, output
current, output voltage, alarm history, input power etc. can be
displayed.
The lifetime of the DC bus capacitor can
be estimated.
The capacitor
,
s condition compared with its initial state can be
confirmed.
All models are equipped with an inrush
current suppression circuit.
An inrush current suppression circuit is provided as standard
in all models, so the cost of peripheral devices such as input
magnetic contactors can be reduced.
A DC reactor (DCR) connection terminal
is provided as standard.
A terminal for connection of a DCR, necessary for suppressing
harmonics, is provided in all models.
The alarm history for the 4 latest
alarms is recorded.
Detailed information from back as far as the 4 latest alarms
can also be checked.
It is possible to output lifetime forecast
signal to the transistor output.
This signal is output when the capacitors in the DC bus circuit,
the electrolytic capacitors on the PCB or the cooling fans are
nearing the end of their service life.

Use of a long-life cooling fan (design life: 7 years with an
ambient temperature: 40°C (104°F) reduces maintenance work.
The menu items include the function menu for checking or
changing function codes, operation monitor , I/O check ,
maintenance info. and alarm info. See the FRENIC-Mini
User
