PF Min Current
PF Detection Minimum Current Level
PF detection minimum current level; % of drive rated current. Used for both,
standard method and dv/dt method (only during run, not evaluated for dv/dt
detection method at start)

dv/dt TuneFactor
dV/dt tuning factor
Factor applied to the dv/dt value(s) which have been determined during tuning.
The result is stored to the parameter(s) if tuning was completed successfully.

PF dVdt ErrCount
PF detection error counter
Shows a percentage value less than 100%. If the value is different to zero,
there have been dv/dt threshold exceeding events. Upon reaching 100%, PF
fault is triggered and the counter is reset to 0%.
Note:
Only applies for dv/dt Input Phase Loss detection method.

PF Max dVdtValue
PF detection maximum dV/dt value
Shows the maximum dv/dt value from the previous (or the current, while
running) travel. The value is reset at start and only updated while the drive is
running. When powering on (no previous travel), zero is shown.
The value is shown as absolute maximum dv/dt value (the internal value is
negative). The unit of this value is V/s but not shown in the operator.
Note:
Only applies for dv/dt Input Phase Loss detection method.

PF dVdtValue
PF detection actual dV/dt value
Shows the current dv/dt value with sign. The value unit is V/s but not shown in
the operator.
Note:
Only applies for dv/dt Input Phase Loss detection method.

Overview
When you activate Direct Landing, the drive decelerates within a fixed distance to the floor level while it does a
positioning operation. You can define the distance to the floor, and also the frequency reference when Direct
Landing is activated.
