18.6.9 Driver life diagnosis function
The driver life diagnosis function via a network is available with drivers
You can check the cumulative energization time and the number of on/off times of the inrush relay based on
the data in the driver. This function gives an indication of the replacement time for parts of the driver including
a capacitor and a relay before they malfunction. The information of the driver life diagnosis function can be
obtained with the following objects.
The cumulative energization time of
the driver is returned.
Number of inrush
relay on/off times
The number of on/off times of the
inrush relay of the driver is returned.
