CHAPTER 6 - DETAILED PARAMETER DESCRIPTION

6.3.1 Parameters for Crane Applications and for Torque Master/Slave Function - P351 to P368

[Factory Setting]
Parameter
(1)

This parameter
is shown on the
display(s) only when
P202 = 3 or 4.
(1)
P352
Delay for E34
Long Period at
Torque Limitation
This parameter
is shown on the
display(s) only when
P202 = 3 or 4.
(1)
P353
Delay for N < Nx
Brake Activation
P354 (1)
Delay for Resetting
the Integrator of the
Speed Regulator
This parameter
is shown on the
display(s) only when
P202 = 4 (vector
with encoder)
P355 (1)
Delay for Accepting
new "Start/Stop"
commands
208
Range
Unit Description / Notes
0.0 to 99.9
If the difference between N (Real Speed) and N* (Speed Reference)
[ 99.9 ]
remains greater than the value set at parameter P292 for a period longer
0.1 s
than that set at parameter P351 the inverter will trip with an error code
E33.
99.9 = E33 is disabled
0 to 999
If the CFW-09 remains at torque limitation for a period longer than the
[ 999 ]
value set at P352 the inverter will trip with an error code E34.
1 s
999 = E34 is disabled.
NOTE!
When the CFW-09 is used in "master/slave" applications, disable
this function on the slave inverter.
0.0 to 20.0
Defines the time to activate the brake, i.e., the time that elapses between
[0.0]
the condition N < Nx and the brake activation.
0.1 s
0.0 to 10.0
This adjustment is needed to ensure that the motor current will be reduced
[2.0]
after the brake activation.
0.1 s
ATTENTION!
If this value is lower than time needed to activate the mechanical
braking, jerking, swinging or even falling may happen. If this value is
greater than that set at P351 or P352, the inverter may trip with an
error code E33 or E34, respectively.
0.0 to 10.0
This is the dead time that ensures the braking activation. Any other
[1.0]
"Start/Stop" command is not accepted during this period.
0.1 s
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.
