P6.49 Input Phase Loss Treatment (OrP)
Range/Units (Format: 16-bit binary)
0: Warn and ramp to stop
1: Warn and coast to stop
Over ripple protection.
To prevent damage to the capacitors from overheating due to an input phase loss, the drive will
monitor the input phases. This is done by monitoring the DC bus ripple amplitude and frequency.
The detection time is related to the output current shown below.
Current (%)
Time (seconds)
When the input voltage is greater than the setting in P6.70 for the time determined in the table
above, this situation is seen as an input phase loss. An error message OrP will be shown on the
keypad.
Related parameters: P6.69, P6.70
P6.50 GFF Detect Current Level (% of INV I-Rated)
Range/Units (Format: 16-bit unsigned)
0�0~100�0% (% of drive rated current)
The Ground Fault Filter (GFF) level is a user settable level of output current difference between
phases that can be tolerated within the time frame specified in P6.51.
P6.51 GFF Low Pass Filter Gain
Range/Units (Format: 16-bit unsigned)
0�00~655�35 seconds
When the drive detects the unbalanced three-phase output current that is higher than the setting
of P6.50 for the time specified in P6.51, GFF protection will be activated. The drive will stop at this
point.
P6.52 Low Current Level
Range/Units (Format: 16-bit unsigned)
0�0~100�0%
Percentage of drive's rated current that will trigger the action selected in P6.54 if the current is
below P6.52 for the time specified in P6.53. An under-current fault (uC) will occur if enabled.
P6.53 Low Current Detection Time
Range/Units (Format: 16-bit unsigned)
0�00~360�00 sec
The current must be greater than the setting in P6.52 before the time limit specified in P6.53
elapses or else the action selected in P6.54 will be initiated. An under-current (uC) will occur if
enabled.
