Alarm threshold, motor overtemperature

130.0 °C

Defines the alarm threshold for the motor overtemperature protection. This threshold, where either a shutdown (trip) or Imax reduction is initiated (P0610) always lies 10 % above the alarm threshold.

ϑtrip = 1.1⋅ ϑwarn = 1.1⋅ P0604	ϑwarn : Warning threshold (P0604)
	ϑtrip : Trip threshold (max. permissible temperature)

The alarm threshold should be at least 40 °C greater than the ambient temperature P0625.

P0604 ≥ P0625 + 40 °C

Inverter temperature reaction		2
Defines reaction when motor temperature reaches warning threshold.
0	No reaction, warning only
1	Warning and Imax reduction (results in a lower output frequency)
2	Warning and trip (F0011)
Motor overload factor [%]		150.0 %

Defines motor overload current limit in [%] relative to p0305 (rated motor current). Limited to maximum inverter current or to 400 % of rated motor current (p0305), whichever is the lower.
