Profile Algorithm
(OPC03)
The following bits determine the algorithm for each clamp open profile.
- BIT 06 configures the open slow profile
- BIT 04 configures the third clamp open profile
- BIT 02 configures the second clamp open profile
- BIT 00 configures the first clamp open profile
0 = Velocity vs. Position algorithm
1 = Pressure vs. Position algorithm
We recorded the value of 1 for pressure vs. position on
Worksheet 8-E.
Important: All other bit selections in OPC03 should be zero.
Expert Response Compensation
(OPC04)
- BITs 15, 14, 13, 12, 11, 10, 09, and 08 determine whether you apply
Expert Response Compensation (ERC) to clamp open profiles. ERC
is an exclusive algorithm that adjusts for changes in your machine,
hydraulics, raw materials, and other process variables. It
compensates for abrupt upsets and long run term deviations.
0 = Expert Response Compensation ON
1 = Expert Response Compensation OFF
We recorded the value of 1 (ERC = Off) on Worksheet 8-E.
OpenĆloop or ClosedĆloop Control
(OPC04)
- BITs 07, 06, 05, 04, 03, 02, 01, and 00 determine whether you use
open- or closed-loop control of clamp open profiles. In open loop, a
valve position moves the cylinder without sensor feedback. In closed
loop, sensor feedback controls the valve regulating pressure or flow.
0 = Closed loop
1 = Open loop
We recorded the value of 1 for open-loop control on Worksheet 8-E.
Important: All other bit selections in OPC03 should be zero.
