Unit Description / Notes
0.0 to 10.0
This is the time that the CFW-09 waits before enabling the ramp after
[ 0.0 ]
receiving the "Start" command.
0.1 s
0.00 to 9.99
Time constant of the filter applied to the torque current. The sampling
[0.00]
time is 5 ms.
0.01 s
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 outputs AO3 and
AO4 when they are set to the option "Iq with P357" (P255 and/or P257 =
38).
0.00 to 9.99
Establishes the percentage of hysteresis that is applied to the
[2.00]
commutation of a digital (DOx) or relay output when they are set to the
0.01 %
options 34 or 35.

0 to P134
The motor accelerates up to the stabilization speed and remains at this
[90]
speed during the time set at parameter P363.
1 rpm
During this period, the CFW-09 detects the load condition by using the
average current.
