This parameter can be changed only with disabled inverter (stopped motor).

Range
Programs all parameters to the standard factory default,
0 to 999
when P204=5.
[ 0 ]
The parameters P142 (max. output voltage), P145 (field
-
weakening frequency), P156 (motor overload current),
P169 (maximum output current) are not changed when
the factory default parameters are loaded through
P204=5.
In the event of a fault trip, except for E14, E24 and E41,
0 to 255s
the inverter can start an automatic reset after the time
[ 0 ]
given by P206 is elapsed.
1s
If P206 2 Auto-Reset does not occur.
If after Auto-Reset the same fault is repeated three ti-
mes consecutively, the Auto-Reset function will be
disabled. A fault is considered consecutive if it happens
again within 30 seconds after the Auto-Reset. Thus if a
fault occurrs four times consecutively, this fault remains
indicated permanently (and inverter disabled).
It allows that the read-only parameter P002 indicates the
0.0 to 100
motor speed in any value, for instance, rpm.
[ 1.0 ]
The indication of P002 is equal to the output frequency
value (P005) multiplied by the value of P208, i.e., P002
0.01 (<10.0)
= P208 x P005.
0.1 (>9.99)
Always when the valuue of the multiplication of P208 x
P005 is higher than 999, the displayed value remains at
999.
0.0 to 15.0Hz
Defines the point where there is automatic gradual
[ 15.0Hz ]
reduction of the switching frequency.
0.1Hz
This improves considerably the measurement of the
output current at low frequencies, and consequently
improves the inverter performance.
In application where it is not possible to operate the in-
verter at low frequencies, ex. 2.5kHz (for instance, due to
acoustic noise), set P219=0.00.
