	(G135)		the main setpoint.
			The lowest value in each case of the connectors selected via the 4 indices
			is applied as the limit.
			Note: Negative values at the selected connectors result in a negative
			maximum value at the output of the limitation.

	(G135)		the main setpoint.
			The lowest value in each case of the connectors selected via the 4 indices
			is applied as the limit.
			Note: Positive values at the selected connectors result in a positive
			minimum value at the output of the limitation.
