P1140 BI: RFG enable
P1141 BI: RFG start
P1142 BI: RFG enable setpoint
The ramp-function generator itself is enabled after the pulses have been enabled
(inverter enable) and after the excitation time has expired (P0346). After limiting to
the maximum speeds for the positive and negative directions of rotation (P1082, -
P1082 or 0 Hz for the direction of rotation inhibit) the setpoint speed for the control
is obtained (r1170).
NOTE
The maximum frequency of the setpoint channel is set using parameter P1080.
In V/f mode the maximum frequency is 650 Hz.
In vector mode the maximum frequency it is limited to 200 Hz (r1084).

BICO parameters for ramp-function generator
Parameter Description
The ramp-function generator output is set to 0 if the
binary signal = 0.
The ramp-function generator output keeps its actual
value if the binary signal = 0.
If the binary signal = 0, then the ramp-function
generator input is set to 0 and the output is reduced
to 0 via the ramp-function generator ramp.
