Expert Response Compensation (ERC) Percentage
Word Description
OSC05 Minimum Velocity Control ERC Percentage [31]
Although error coding allows range of 00000 to 09999, the module limits it to a minimum of 01000.
OSC06 Minimum Pressure Control ERC Percentage [31]
Although error coding allows range of 00000 to 09999, the module limits it to a minimum of 01000.
OSC07 Open
Watchdog Timer
Word Description
OSC08 Profile Watchdog Timer Preset [21] When the module starts the Clamp Open Slow Profile, it:
S starts an internal Profile Watchdog timer
S stops this timer and reset its accumulated value to zero (after reporting total execution time in OPS60) when it completes the profile
S sets master status bit SYS04-B13 when the accumulated value of this timer equals or exceeds this entry .
A zero entry inhibits SYS04-B13.
