Setting and Monitoring Methods
Use the same methods for the Cumulative ON Time Monitor (refer to the previous function).
7-2-8 Conduction Time Monitor
■
Functions
• The time that power is supplied to the Slave’s internal circuit power supply is totaled and recorded
every 0.1 hours (six minutes).
• The DeviceNet Communications Unit/Card has three monitor values that can be set independently
for the following three time monitoring functions. Each of these values, however, is a total of the
time that the Inverter’s power is ON, and the fan and electrolytic capacitor are not monitored sepa-
rately. Use these operating times as a guide for when the corresponding parts need to be replaced.
• When the Main Unit operating time reaches or exceeds the monitor value, the Unit Maintenance
Flag will turn ON in the Unit’s Status Area.
• When the fan operating time or electrolytic capacitor operating time reaches or exceeds the monitor
value, the Unit Maintenance Flag (fan or electrolytic capacitor) will turn ON in the Unit’s Status
Area.
• Since the fan operating time and electrolytic capacitor operating time are used to indicate when
those parts need to be replaced, these monitoring times can be reset to zero
Note The Conduction Time is written to the EEPROM (in the DeviceNet Communications Unit or
Card) approximately every six minutes. Therefore, depending on the power OFF timing, up to
six minutes worth of data may be lost. To monitor more closely, click the
Save Maintenance
Counter Button located on the General Tab Page of the Maintenance Information Window
immediately before turning OFF the power. The maintenance information including the Con-
duction Time will be written to the EEPROM.
Main Unit operating time Cannot be reset.
Fan operating time The present value can be reset to zero.
Electrolytic capacitor
operating time
The present value can be reset to zero.
