Possible Settings:

0Reduce output frequency

1Trip (F0004)

2Reduce pulse frequency and output frequency

3Reduce pulse frequency then trip (F0004)

Notice:

P0290 = 0:

Reduction of output frequency is only effective if the load is also reduced. This is for example valid for variable torque applications with a quadratic torque characteristic as pumps or fans.

A trip will always result, if the action taken does not sufficiently reduce internal temperature.

The pulse frequency P1800 is reduced only if higher than 2 kHz. The actual pulse frequency is displayed in parameter r1801.
