Section 5.7.16 Parameter 016 - Crankshaft Angle
Value:
Standard Numeric
Meaning:
The angle of the press crankshaft in .01 degrees. Note that if “Send Decimal Point” is “No”, then the
PLC must assume a decimal position of two. For example:
30 degrees would be sent as 3000
45.6 degrees would be sent at 4560
359 degrees would be sent as 35900
etc.
Due to serial port speed limitations, this value should not be considered a real-time angle value. It
can, however, provide an accurate measurement of where the press stopped. See parameter 023 for
determining if the press is running or not.
Section 5.7.17 Parameter 017 - Effective Flywheel Speed.
Value:
Standard Numeric
Meaning:
The effective flywheel speed in RPM. The accuracy of this value depends on calibration (see
OmniLink Press Control Manual). Note that the flywheel may not actually be turning at this RPM
(typical for geared presses) but this value represents the speed the crankshaft should turn when the
clutch is engaged.
Section 5.7.18 Parameter 018 - Crankshaft Speed.
Value:
Standard Numeric
Meaning:
The actual crankshaft speed in RPM This value is read from the resolver on the press crankshaft. It
should be zero when the clutch is not engaged.
