Velocity Control Limits
Word Description
TCC45 Velocity Minimum Control Limit [08] Minimum controllable clamp velocity attainable during any Vel/Pos Third Clamp Close Profile.
The module expects this clamp velocity when setting its selected velocity valve to the %-output in TCC47.
TCC46 Velocity Maximum Control Limit [08] Maximum controllable clamp velocity attainable during any Vel/Pos Third Clamp Close Profile.
The module expects this clamp velocity when setting its selected velocity valve to the %-output in TCC48.
TCC47 Selected Velocity Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected velocity valve
during any Vel/Pos Third Clamp Close Profile. The module expects a velocity equal to TCC45 when setting the selected velocity
valve to this %-output during profile execution. The Vel/Pos Third Clamp Close Profile will be executed as a reverse-acting algorithm
if this entry is greater than TCC48.
TCC48 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 Third Clamp Close Profile. The module expects a velocity equal to TCC46 when setting the selected veloc-
ity valve to this %-output during profile execution. The Vel/Pos Third Clamp Close Profile will be executed as a reverse-acting algo-
rithm if this entry is less than TCC47.
Profile Tuning Constants
Word Description
TCC49 Proportional Gain for Pressure Control [30]
TCC50 Integral Gain for Pressure Control [27] or [28]
TCC51 Derivative Gain for Pressure Control [26] or [21]
TCC52 Proportional Gain for Velocity Control [28]
TCC53 Feed Forward Gain for Velocity Control [30]
TCC54 - 56 Open
Profile Pressure Alarm Setpoint
Word Description
TCC57 Profile High Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when executing the
Third Clamp CloseProfile. The module sets alarm status bit SYS05-B14 when clamp pressure equals or exceeds this entry during
the Third Clamp Close Profile. A zero entry inhibits SYS05-B14.
TCC58 - 64 Open
