Control limits let you span your selected valve outputs for effective control
with either direct-acting or reverse-acting valves. Your machine
manufacturer typically provides you with values to configure these limits.
Minimum Pressure Control Limit
(FCC41, SCC41, TCC41, LPC41, INC41, PKC41, HDC41, PLC41, FOC41, SOC41,
TOC41, OSC41)
The value in this word corresponds to the minimum controllable pressure
during the respective profile. The QDC module uses this word with the
Selected Pressure Valve, Output for Minimum (word 43) below. The QDC
module expects this pressure when setting the selected pressure valve to
the percentage output you enter in word 43.
We entered zero on corresponding worksheets.
Maximum Pressure Control Limit
(FCC42, SCC42, TCC42, LPC42, INC42, PKC42, HDC42, PLC42, FOC42, SOC42,
TOC42, OSC42)
The value in this word corresponds to the maximum controllable pressure
during the respective profile. The QDC module uses this word with the
Selected Pressure Valve, Output for Maximum (word 44) below. The QDC
module expects this pressure when setting the selected pressure valve to
the percentage output you enter in word 44.
Enter an initial control limit equal to the maximum pressure available
through the selected pressure valve during the profile.
Selected Pressure Valve, Output for Minimum
(FCC43, SCC43, TCC43, LPC43, INC43, PKC43, HDC43, PLC43, FOC43, SOC43,
TOC43, OSC43)
The QDC module uses this word with the Minimum Pressure Control
Limit (word 41) above. Enter the %-signal output that the QDC module
uses to drive the selected pressure valve for minimum profile pressure.
The QDC module expects a pressure equal to word 41 when setting the
selected pressure valve to this percentage output.
