Figure 15.3 (b): Hot motor overload curves for loads of the HD and ND types
For the previous example, by plotting the 678 % value (x axis) of the Overload Current with the 4 seconds (y axis)
of the Overload Time in the graph of the
figure 15.3
(b)
(hot motor), the thermal class to be selected will be the
class 15 (t15).

Description:
When a fault occurs (except F067 – Inverted Encoder/Motor Wiring and F099 – Invalid Current Offset), the
inverter can reset itself automatically after the time set in P0340 has elapsed.
NOTE!
The faults F051, F078 and F156 allow a conditional Reset, i.e., the Reset will only occur if the
temperature gets back to the normal operation range.
