Automation and Drives - SCE

Output Parameters:

Parameter	Data	Value Range	Default	Description
	Type
LMN	REAL	0.0		MANIPULATED VALUE. At the output "Manipulated value",
				the effectively active manipulated value is read out in the
				floating point format.
LMN_PER	WORD	W#16#0000		MANIPULATED VALUE PERIPHERY. The manipulated value
				in the periphery format is wired to the controller at the output
				of "Manipulated value periphery“.
QLMN_HL	BOOL	FALSE		HIGH LIMIT OF MANIPULATED VALUE REACHED. The
				manipulated value is always limited to a high and low limit.
M
				The output "High limit of manipulated value reached" signals
				that the high limit has been exceeded.
QLMN_LL	BOOL	FALSE		LOW LIMIT OF MANIPULATED VALUE REACHED. The
				manipulated value is always limited to a high and low limit.
M
				The output "Low limit of manipulated value reached" signals
				that the low limit is underrange.
LMN_P	REAL	0.0		PROPORTIONALITY COMPONENT. The output "P-
				component" contains the proportional component of the
				manipulated variable.
LMN_I	REAL	0.0		INTEGRAL COMPONENT. The output "I-component“
				contains the integral component of the manipulated variable.
LMN_D	REAL	0.0		DERIVATIVE COMPONENT. The output "D-component"
				contains the derivative component of the manipulated
				variable.
PV	REAL	0.0		PROCESS VARIABLE / actual value. At the output "Actual
				value", the effectively active actual value is read out.
ER	REAL	0.0		ERROR SIGNAL / System deviation. At the output "System
				deviation", the effectively active system deviation is read out.
