MCC
MCC27 Clamp Position Minimum Software Travel Limit [13] The module continuously compares real-time clamp position against this entry.
The module sets alarm status bit SYS07-B02 and forces all of its outputs to zero when executing a clamp close profile and clamp
position is less than or equals this entry. A zero entry inhibits SYS07-B02.
MCC28 Clamp Position Maximum Software Travel Limit[13] The module continuously compares real-time clamp position against this entry.
the module sets alarm status bit SYS07-B03 and forces all of its outputs to zero when executing a clamp open profile and clamp
position equals or exceeds this entry. A zero entry inhibits SYS07-B03.
MCC29 Clamp Software Travel Limit Alarm Deadband [17] After sensing a clamp overtravel and latching alarm status bit SYS07-B02 or
SYS07-B03, the module will not unlatch bit until real-time clamp position is inside the overtravel setpoint by an incremental length
equal to this entry. This incremental position will be added to MCC27 in order to determine the clamp position required to unlatch
SYS07-B02. This incremental position will be subtracted from MCC28 in order to determine the clamp position required to unlatch
SYS07-B03.
MCC30 Clamp Position Transducer Digital Filter [23] A non-zero entry forces the module to filter the input before using the result for all
clamp position calculations. Use this parameter to soften the input signal from a linear potentiometer.
Clamp Pressure Transducer Configuration
The module accesses data in MCC31-MCC36 if bit patterns in
MCC02 and MCC03 indicate that the module is connected to a
clamp pressure sensor.
Word Description
MCC31 Minimum Clamp Pressure [02]
MCC32 Maximum Clamp Pressure [02]
MCC33 Analog Signal at Minimum Clamp Pressure [24]
MCC34 Analog Signal at Maximum Clamp Pressure [24]
MCC35 High Clamp Pressure Alarm Setpoint [02] The module continuously compares real-time clamp pressure against this entry. and sets
alarm status bit SYS05-B01 when clamp pressure equals or exceeds this entry. A zero entry inhibits SYS05-B01.
MCC36 Clamp Pressure Alarm Time Delay [23] Total time the module must monitor a continuous clamp pressure in excess of the non-
zero entry in all clamp pressure alarm setpoints before setting the associated alarm status bit. Setpoint/bit pairs affected are:
Setpoint Alarm Status Bit
MCC35 SYS05-B01
JGC07 SYS05-B10
FCC57 SYS05-B12
SCC57 SYS05-B13
TCC57 SYS05-B14
LPC57 SYS05-B15
FOC57 SYS06-B09
SOC57 SYS06-B10
TOC57 SYS06-B11
OSC57 SYS06-B12
Use a non-zero entry in this word to filter out clamp pressure spikes of short enough duration to avoid nuisance alarms.
Ejector Position Transducer Configuration
The module accesses data in MCC37-MCC44 if bit patterns in
MCC02 and MCC03 indicate that the module is connected to an
ejector position sensor.
Word Description
MCC37 Minimum Ejector Position [15]
MCC38 Maximum Ejector Position [15]
MCC39 Analog Signal at Minimum Ejector Position [24]
MCC40 Analog Signal at Maximum Ejector Position [24]
MCC41 Ejector Position Minimum Software Travel Limit [15] The module continuously compares real-time ejector position against this entry.
The module sets alarm status bit SYS07-B04 and forces all of its outputs to zero when executing an ejector retract profile and ejector
position is less than or equals this entry. A zero entry inhibits SYS07-B04.
