Parameter
Description
Used to set the filtering time for external pulse command signals.
When the user sets Pn011 = 12 (12 × 12.5ns = 150ns), a filter width duration of less than 150ns will
be treated as an interference signal.

< 150 ns
When The pulse width of this segment is less than
150ns, it is considered as low alignment, so the
two input pulses are considered as one pulse.

When the width of High, Low-duty pulse is
greater than 150ns, it can ensure that the pulse
command is not filtered out
When the pulse width of this segment is less
than 150ns, it is considered as low alignment, so
two input pulses are considered as one pulse.
Calculation method
: the maximum pulse frequency sent by the user's upper unit mount is f kHz,
then.

Note:
The custom time is calculated based on when the hardware filter is turned off, and the custom
time is adjusted according to the actual working conditions after the hardware filter is actually turned
on.

Parameter
Description
When an external regenerative resistor is connected, the regenerative resistor power is set to a value
that matches the connected external regenerative resistor.
Note:
The setting value varies depending on the cooling of the external regenerative resistor. When
an alarm occurs and the regenerative resistor temperature is not high at that time, the corresponding
power value can be set large; conversely, set a smaller value.
