n Alarm Outputs for Maintenance Monitors
An output can be set up to inform the user when a specific components has neared its expected
performance life.
When one of multi-function digital output terminals has been assigned the maintenance
monitor function (H2-oo = 2F), the terminal will close when the cooling fan, DC bus
capacitors, or DC bus pre-charge relay reach 90% of the expected performance life, or when
the IGBTs have reached 50% of their expected performance life. Additionally the digital
operator will display an alarm like shown in
that may need maintenance.

<1> This alarm message will be output only if the Maintenance Monitor function is assigned to one of the digital
outputs (H2-oo = 2F). The alarm will also trigger a digital output that is programmed for alarm indication (H2-
oo = 10).

Displays the accumulated cooling fan operation time as a percentage of the
specified maintenance period (displayed in percent %).
Displays the accumulated time the capacitors are used as a percentage of the
specified maintenance period.
Displays the number of times the drive is powered up as a percentage of the
performance life of the inrush circuit.
Displays the percentage of the maintenance period reached by the IGBTs.
