Description / Notes
If the difference between N (Real Speed) and N* (Speed Reference)
remains greater than thevaluesetat parameter P292for a period longer
than that set at parameter P351 the inverter will trip with an error code
E33.
99.9 = E33 is disabled

Speed without Control
0.1 s
This parameter
is shown on the
display(s) only when
P202 = 3 or 4.
If the CFW-09 remains at torque limitation for a period longer than the
value set at P352 the inverter will trip with an error code E34.
999 = E34 is disabled.
NOTE!
When the CFW-09 is used in “master/slave” applications, disable
this function on the slave inverter.

This parameter
is shown on the
display(s) only when
P202 = 3 or 4.
Defines thetime to activatethe brake,i.e., thetime that elapses between
the condition N < Nx and the brake activation.

ATTENTION!
If this value is lower than time needed to activate the mechanical
braking,jerking, swinging or even falling mayhappen.If this value is
greater than that set at P351 or P352, the inverter may trip with an
error code E33 or E34, respectively.

Speed Regulator
This parameter
is shown on the
display(s) only when
P202 = 4 (vector
with encoder)
This is the dead time that ensures the braking activation. Any other
“Start/Stop” command is not accepted during this period.
Defines the time that the CFW-09 waits before accepting a new “Start”
command after the motor is stopped. During the period set at P355 the
commands are ignored.
