 Simple and enhanced maintenance / enhanced protective functions.
 Information concerning life of consumable inverter parts is displayed.
Main circuit capacitance
Inverter cumulative running
time
 Life warning signal can be output to transistor output.
Output when the end of service life of main circuit capacitors, electrolytic capacitors on PC board,
cooling fan, or real time lock battery (optional) approaches.
 Information taking equipment maintenance into account is also displayed.
Information is added to maintenance information for the inverter itself and information taking
equipment maintenance into account is also displayed.
Item
Motor cumulative
running time (h)
Startup count (times)
 You can check alarm history for the past 10 times (latest and 9 past times).
Detailed information can also be checked for the past 4 times.
If using a real time clock, you can check the date and time of occurrence.
 Employs detachable interface board (terminal block for control signal line)
Keeps track of time that equipment (motor) using the inverter is actually running.
(Usage example)
If used for fan control, it approximates the time for replacement of belts used for
pulleys.
Counts the number of times the inverter is turned on and off.
(Usage example)
Because it keeps a record of how many times the equipment is turned on and off, it
approximates the times for replacement of equipment parts that place a load on
machinery when turned on and off.
