It is used to display of the input bipolar transistor (IGBT) temperature of the inverter and
IGBT protection against overheating depending on the model.
It shows the total running time of the inverter. If this value reaches the value set in P8.17,
digital output (ON) will be switched on.
P7.12 is used to set the number of decimal places to display the loading speed. The
following example explains how to calculate the loading speed:
Let's assume that P7.06 (coefficient of loading speed the display) is 2,000 and P7.12 is 2 (2
decimal places). If the drive frequency is 40.00 Hz, the load speed is 40.00 x 2000 = 80.00
(display of 2 decimal places).
If the inverter is in the STOP state, the loading speed is the speed corresponding to the set
frequency, namely "set loading speed". If the frequency is set to 50.00 Hz, the loading
speed in STOP state is 50.00 x 2.000 = 100.00 (2 decimal places).
