4.5.3 Manipulated voltage limitation
5474
OUTPUT_VOLTAGE_POS_LIMIT [n] 0...7 index of the parameter set
Cross reference: -
Manipulated voltage limitation positive Related to:
HLA
Protection level:
3/3
Unit:
V
Default:
10.0
Minimum:
1.0
Maximum:
10.0
Data type:
FLOAT
Active:
Immediately
The manipulated variable setpoint is limited in the positive direction to the value
set in MD 5474 before the D/A conversion. A message is sent to the PLC if the
limit is violated.
5475
OUTPUT_VOLTAGE_NEG_LIMIT [n] 0...7 index of the parameter set
Cross reference: -
Manipulated voltage limitation negative Related to:
HLA
Protection level:
3/3
Unit:
V
Default:
10.0
Minimum:
1.0
Maximum:
10.0
Data type:
FLOAT
Active:
Immediately
The manipulated variable setpoint is limited in the negative direction to the value
set in MD 5475 before the D/A conversion. A message is sent to the PLC if the
limit is violated.
5476 OUTPUT_VOLTAGE_INVERSION Cross reference: -
Manipulated variable inversion
Bit 0= 0: No inversion
1: Inversion
Related to:
HLA
Protection level:
3/3
Unit:
-
Default:
0
Minimum:
0
Maximum:
1
Data type:
UNS.WORD
Active:
Immediately
The voltage output (manipulated variable) can be inverted in machine data MD
5476 in order to compensate for differences in sign in the piping or wiring. Alter-
natively, the wiring of the manipulated variable for the valve could be altered.
Definition of direction: See Subsection 3.9.1.
