This is the time that the CFW-09 waits before enabling the ramp after
receiving the “Start” command.

0.1 s
Time constant of the filter applied to the torque current. The sampling
time is 5 ms.
It works along with P358 and activates a digital or relay output that was
set to the option Torque Polarity +/-.
The filtered torque current may be available at analog outputsAO3 and
AO4 when theyare set to the option “Iq with P357” (P255 and/or P257 =
38).

Establishes the percentage of hysteresis that is applied to the
commutation of a digital (DOx) or relay output when they are set to the
options 34 or 35.

The motor accelerates up to the stabilization speed and remains at this
speed during the time set at parameter P363.
During this period, the CFW-09 detects the load condition by using the
average current.
