BONFIGLIOLI Active Cube User Manual

If Ramp Setpoint 434 = 2 (reference line value only), this reference line value is lim-
ited to fmin.
The sign in front of fmin
with reference value = 0 is derived from the sign in front of
the last reference line value which was not 0.
After Mains On, the reference line value is limited to +fmin.
For Ramp Setpoint 434 = 3, the sign of the total reference value results from the
total of internal reference frequency and reference line value.
The reference values can be controlled at the frequency inverter via the control unit or
the control software VPlus via the following parameters:

11.3.4 Example sequence
In configurations without Motion Control (Configuration 30 ≠ x40), the PLC must
send the correct sequence:
1
Control word =
0x0000
Disable voltage
2
Control word =
0x0006
Shut down
3
Control word =
0x0007
Switch On
4
Control word =
0x000F
Enable operation
OR
1
Control word =
0x0000
Disable voltage
2
Control word =
0x000F
Enable operation
In configurations without positioning control (Configuration 30 ≠ x40), the second
(shortened) sequence can be used, because transition
4‘ is available in these config
u-
rations.
