Pressure Control Limits
Word Description
FCC41 Pressure Minimum Control Limit [02] Minimum controllable clamp pressure attainable during any Press/Pos First Clamp Close Pro-
file. The module expects this clamp pressure when setting its selected pressure valve to the%-output in FCC43.
FCC42 Pressure Maximum Control Limit [02] Maximum controllable clamp pressure attainable during any Press/Pos First Clamp Close
Profile. The module expects this clamp pressure when setting its selected pressure valve to the%-output in FCC44.
FCC43 Selected Pressure Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected pressure
valveduring any Press/Pos First Clamp Close Profile. The module expects a pressure equal to FCC41 when setting the selected
pressure valve to this %-output during profile execution. The Press/Pos First Clamp Close Profile will be executed as a reverse-act-
ing algorithm if this entry is greater than FCC44.
FCC44 Selected Pressure Valve Output for Maximum [19] 100% CV output percentage that Module uses to drive the selected pressure
valveduring any Press/Pos First Clamp Close Profile. The module expects a pressure equal to FCC42 when setting the selected
pressure valve to this %-output during profile execution. The Press/Pos First Clamp Close Profile will be executed as a reverse-act-
ing algorithm if this entry is less than FCC43.
Velocity Control Limits
Word Description
FCC45 Velocity Minimum Control Limit [08] Minimum controllable clamp velocity attainable during any Vel/Pos First Clamp Close Profile.
The module expects this clamp velocity when setting its selected velocity valve to the %-output in FCC47.
FCC46 Velocity Maximum Control Limit [08] Maximum controllable clamp velocity attainable during any Vel/Pos First Clamp Close Profile.
The module expects this clamp velocity when setting its selected velocity valve to the %-output in FCC48.
FCC47 Selected Velocity Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected velocity valve
during anyVel/Pos First Clamp Close Profile. The module expects a velocity equal to FCC45 when setting the selected velocity
valve to this %-output during profile execution. The Vel/Pos First ClampClose Profile will be executed as a reverse-acting algorithm
if this entry is greater than FCC48.
FCC48 Selected Velocity Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected velocity
valve during any Vel/Pos First Clamp Close Profile. The module expects a velocity equal to FCC46 when setting the selected veloc-
ity valve to this %-output during profile execution. The Vel/Pos First Clamp Close Profile will be executed as a reverse-acting algo-
rithm if this entry is less than FCC47.
Profile Tuning Constants
Word Description
FCC49 Proportional Gain for Pressure Control [30]
FCC50 Integral Gain for Pressure Control [27] or [28]
FCC51 Derivative Gain for Pressure Control [26] or [21]
FCC52 Proportional Gain for Velocity Control [28]
FCC53 Feed Forward Gain for Velocity Control [30]
FCC54 - 56 Open
Profile Pressure Alarm Setpoint
Word Description
FCC57 Profile High Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when executing the
First Clamp Close Profile. The module sets alarm status bit SYS05-B12 when clamp pressure equals or exceeds this entry during
the First Clamp Close Profile. A zero entry inhibits SYS05-B12.
