No-Flow Activation
Level
NF Act. Level
When the motor RPM falls below the programmed level in P2-12, the
no-flow detection will activate. A value of 0 disables this function.

P2-12 010CH
No-Flow Detection
Bandwidth
NF Det.Bandwidth
Sets the motor RPM fluctuation bandwidth. No-flow activates when
the motor RPM remains within the programmed bandwidth in P2-12
for a time specified in parameter P2-13.

Alternative Sleep
Activate Level
SLP Act. Level
When P2-01 Sleep Level Type is set for 0 (Output Frequency), the
sleep function becomes active when the output frequency is greater or
equal to the level in P2-20. When programmed to 0, the sleep function
will become active above the P2-02 Sleep Level.
A value of 0 disables this function.
