Table 3-19 BICO parameters for ramp-function generator

	Parameter	Description
P1140	BI: RFG enable	The ramp-function generator output is set to 0 if the
		binary signal = 0.
P1141	BI: RFG start	The ramp-function generator output keeps its actual
		value if the binary signal = 0.
P1142	BI: RFG enable setpoint	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.

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 drive inverter frequency is defined in the setpoint channel using parameter P1080. The maximum possible frequency is 650 Hz.
