P504 Pulse frequency
S
The internal pulse frequency for actuating the power component can be changed with this
parameter. A higher setting reduces motor noise, but leads to increased EMC emissions and
reduction of the possible motor nominal torque.
NOTE: The radio interference suppression limiting curve A1 according to EN55011 is
complied with at a setting of 6.0kHz on condition that the wiring guidelines are
complied with. For further details, see Section 9.4 EMC limit value classes.
3.0 ... 16.0 kHz
{ 6.0 }
NOTE: Raising the pulse frequency leads to a reduction of the possible output current,
depending on the time (I
2
t curve). For further details, see Section 9.5 Reduced
output power.
P505 Absolute mini mum freq uency
S P
0.0 ... 10.0 Hz
{ 2.0 }
Gives the frequency value that cannot be undershot by the FI. If the setpoint is smaller than the
absolute minimum frequency, the FI switches off or changes to 0.0Hz.
At the absolute minimum frequency, braking control (P434) and the setpoint delay (P107) are
actuated. If a setting value of "Zero" is selected, the brake relay does not switch during
reversing.
When controlling lift equipment, this value should be set at a minimum of 2Hz. From 2Hz, the
current control of the FI operates and a connected motor can supply sufficient torque.
NOTE: Output frequencies < 4.5Hz result in a reduced current overload capacity. For
further details, see Section 9.5 power derating.
P506
Automatic error
acknowled gement
S
0 ... 7
{ 0 }
In addition to the manual error acknowledgement, an automatic acknowledgement can also be
selected.
0 = No automatic error acknowledgement
1 ... 5 = Number of permissible automatic error acknowledgments within one mains-on cycle.
After mains off and switch on again, the full amount is again available.
6 = always , an error message will be acknowledged automatically if the cause of the error is
no longer present.
7 = quit disable (via enable deactivated) , acknowlegement is only possible with the OK
key or by switching off the mains. Acknowledgement is not implemented by removing
the enable!
