YNRM = MPOS or YNRM = FLOW
Presetting: YA = 0% and YE = 100%
Example:
YNRM = MPOS with YA = 10 % and YE = 80 %
Example:
YNRM = FLOW with YA = 10 % and YE = 80 %

Tight closing with manipulated variable
With this function the valve can be driven to the seat with the maximum
actuating force of the actuator (continuous contact of the
piezo--valves). The tight closing function can be activated on one side
or for both limit positions. YCLS becomes active when the setpoint is
below YCDO or above YCUP (figure 61, page 103).
NOTE
When the tight closing function is activated, monitoring for the control
deviation is switched off for the respective overflow direction
(YCDO: < 0 %, YCUP: > 100 %) for parameter 45. LIM. We
recommend parameter 48. ZERO and 49. OPEN in the end positions
for long--term monitoring.
