Dependency: Following physical values influence the converter overload protection (see diagram):
•
Heat sink temperature (r0037[0]); causes A504 and F4.
• IGBT Junction temperature (r0037[1]); causes F4 or F6.
•
Delta temperature between heat sink and junction temperature; causes A504 and F6.
• Converter I

t (r0036); causes A505 and F5.
Notice: P0290 = 0, 2:
• Reduction of output frequency is only effective if the load is also reduced.
This is for example valid for light overload applications with a quadratic torque characteristic as pumps or fans.
•
For settings P0290 = 0 or 2, the I-max controller will act upon the output current limit (r0067) in case of
overtemperature.
P0290 = 0:
• With pulse frequencies above nominal, pulse frequency will be reduced to nominal immediately in the
event of r0027 greater than r0067 (current limit).
P0290 = 2, 3:
• The pulse frequency P1800 is reduced only if higher than 2 kHz and if the operating frequency is below 2 Hz.
• The actual pulse frequency is displayed in r1801[0] and the minimal pulse frequency for reduction is
displayed in r1801[1].
•
Converter I

t acts upon output current and output frequency, but not on pulse frequency.
A trip will always result, if the action taken does not sufficiently reduce internal temperatures.

Bit 00 for enabling/disabling automatic pulse frequency reduction at output frequencies below 2 Hz. The
benefit is to reduce the noises at frequencies below 2 Hz.
