should make the residual output voltage due to regeneration almost
zero, before the drive resumes operation.
This parameter also determines the search time when performing
external Base-Block and Fault Reset (P72).
P 35 Maximum Current Level for Speed Search
Settings 30 to 200%
Following a power failure, the AC drive will start its speed search
operation only if the output current is greater than the value determined
by P35. When the output current is less than that of P35, the AC drive
output frequency is at a "speed synchronization point" and will accelerate
or decelerate back to the operating frequency at which it was running
prior to the power failure.

Maximum Output Frequency is 60Hz,the Maximum Output Frequency
will be limited to 50Hz.Setting of this parameter must be equal to or
greater than the Lower Bound of OutputFrequency (P37).
P 37 Lower Bound of Output Frequency
Settings
0.00 Hz to 400.0 Hz
Setting of this parameter must be equal to or less than the Upper Bound
of Output Frequency.
If the Lower Bound of Output Frequency is 10Hz, and the Minimum
Output Frequency (P08) is set at 1.0Hz, then any command frequency
between 1-10Hz will generate a 10Hz output from the drive.
