Expert Response Compensation (ERC) Percentage
Word Description
PLC05 Minimum RPM Control ERC Percentage [31]
PLC06 Minimum Pressure Control ERC Percentage [31]
Although error coding allows range of 00000 to 09999, the module limits it to a minimum of 01000.
PLC07 RFU
Watchdog Timer
Word Description
PLC08 Profile Watchdog Timer Preset [21] When the module starts Plastication Profile, it:
starts an internal Profile Watchdog timer
stops this timer and reset its accumulated value to zero (after reporting total execution time in PPS57) when it completes the profile
sets master status bit SYS04-B08 when the accumulated value of this timer equals or exceeds this entry
A zero entry inhibits SYS04-B08.
Unselected Valve Set-output Values
When the module starts the Plastication Profile, it:
• ignores the unselected value of the selected output
• uses ramp rates PLC17-20 and PLC25-28 to ramp unselected outputs
• sets its unselected outputs to the values listed below
Word Description
PLC09 Output #1 Set-output Value during Profile [19]
PLC10 Output #2 Set-output Value during Profile [19]
PLC11 Output #3 Set-output Value during Profile [19]
PLC12 Output #4 Set-output Value during Profile [19]
PLC13-16 Reserved for Future Use
Output Ramp Rates
The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during the Plastication Profile. The module
interprets a ramp rate of zero as a step function ramp (ramp disable).
Word Description
PLC17 Output #1 Acceleration Ramp Rate during Profile [20]
PLC18 Output #2 Acceleration Ramp Rate during Profile [20]
PLC19 Output #3 Acceleration Ramp Rate during Profile [20]
PLC20 Output #4 Acceleration Ramp Rate during Profile [20]
PLC21-24 RFU
PLC25 Output #1 Deceleration Ramp Rate during Profile [20]
PLC26 Output #2 Deceleration Ramp Rate during Profile [20]
PLC27 Output #3 Deceleration Ramp Rate during Profile [20]
PLC28 Output #4 Deceleration Ramp Rate during Profile [20]
