P6.65 to P6.68 is for heavy loads in order to prevent OV or OC faults. A heavy load will be
accelerated to P6.66 and remain there for the time specified in P6.65, then continue to accelerate
to the commanded speed. The same behavior occurs for the Dwell Frequency and Time for the
Decel portion.

0�20
This parameter sets the monitoring time interval to detect an input phase loss. The factory setting
is 0.20 second, which means the drive will check every 0.20 second.
Related parameters: P6.49, P6.70

When the input voltage is greater than the setting in P6.70 for the time determined as shown
below, this situation is seen as input phase loss.
