7.1.17 Warning monitoring
If an attempt is made to set the data conflicting with other data on the inverter, the inverter displays a warning in the
operator.
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 Chapter 9.3 Warning Codes
7.1.18 DC voltage monitoring
When the DC voltage monitoring is selected, the inverter displays the DC voltage 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
7.1.19 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%
IMPORTANT! Please be sure to set the motor nameplate data into appropriate parameters to ensure
proper operation and protection of the motor.
*B012 is the motor overload protection value
*A082 is the motor voltage selection
*H003 is the motor kW capacity
*H004 is the number of motor poles
Please refer to the appropriate pages in this guide and the QRG for further details.
