directions.
Integral-Action Coefficient 1: Integral-action coefficient for both moving directions.
SETP_CUTOFF
Setpoint Cut-Off CLOSE: Lower level for the setpoint cut-off. The transducer
setpoint will be forced to zero if the AO.output is
equal or smaller than this value.
Setpoint Cut-Off OPEN: Upper level for the setpoint cut-off. The transducer
setpoint will be forced to 100% if the AO.output is
equal or greater than this value.
