4.1.27 Trip monitoring 1 to 6

When the trip monitoring function (d081 to d086) is selected, the inverter displays the trip history data. The last six protective trips the inverter made can be displayed.

Select the trip monitoring 1 (d081) to display the data on the most recent trip.

4.1.28 Programming error monitoring

If an attempt is made to set the data conflicting with other data on the inverter, the inverter displays a warning.

The PRG (program) lamp lights up while the warning is displayed (until the data is rewritten forcibly or corrected). For details on the programming error monitoring function, see Section 5.2. Warning Codes

4.1.29 DC voltage monitoring

When the DC voltage monitoring is selected, the inverter displays the DC voltage (across terminals P and N) of the inverter.

While the inverter is operating, the monitored value changes as the actual DC voltage of the inverter changes.

(Display)

0.0 to 999.9 in steps of 0.1 V

4.1.30 BRD load factor monitoring

When the BRD load factor monitoring function (d103) is selected, the inverter displays the BRD load factor. If the BRD load factor exceeds the value set as the dynamic braking usage ratio (b090), the inverter will trip because of the braking resistor overload protection (error code "E06").

(Display)

0.0 to 100.0 in steps of 0.1%

4.1.31 Electronic thermal overload monitoring

When the electronic thermal overload monitoring function (d104) is selected, the inverter displays the electronic thermal overload. If the electronic thermal overload exceeds 100%, the inverter will trip because of the overload protection (error code "E05").

(Display)

0.0 to 100.0 in steps of 0.1%
