• LED monitor on the keypad displaying all types of data
You can access and monitor all types of inverter's data and information including output frequency,
reference frequency, load shaft speed, output current, output voltage, alarm history, input power etc.
using built-in keypad with LED.
Refer to Chapter 3, "OPERATION USING THE KEYPAD."
• Menu mode accessible from the keypad
You can easily access the menu mode including "Data setting," "Data checking," "Drive monitoring,"
"I/O checking," "Maintenance information," and "Alarm information."
Refer to Chapter 3, "OPERATION USING THE KEYPAD."
Maintenance
FRENIC-Mini series features the following facilities useful for maintenance.
Refer to Chapter 3, Section 3.3.5 "Reading Maintenance Information" and the FRENIC-Mini
Instruction Manual, Chapter 7 "MAINTENANCE AND INSPECTION" for details.
• The lifetime of the DC link bus capacitor (reservoir capacitor) can be estimated
The capacitor's condition compared with its initial state can be confirmed.
• Recording and displaying of cumulative running time of the inverter
The inverter records and displays the accumulated running time of the inverter itself, the printed
circuit board and cooling fan.
• Displaying Information that contributes to equipment maintenance
In addition to inverter maintenance information, the inverter displays data that also take equipment
maintenance into consideration.
Item Purpose
Motor cumulative
running time (hr)
The actual cumulative running time of the equipment (motor) using the inverter is
calculated.
<Example of use>
If the inverter is used to control a fan, this information is an indication of the timing
for replacing the belt that is used on the pulleys.
Number of starts
(times)
The number of the inverter start and stop times can be counted.
<Example of use>
The number of equipment start and stop times is recorded, so this information can
be used as a guideline for parts replacement timing in equipment in which starting
and stopping puts a heavy load on the machinery.
