6. Select the CONTINUOUS stroking mode on the press stroking selector and initiate press stroking.
7. The actual stroking speed will be shown at the top of the OmniLink Operator Terminal display
beside Stroke Speed as long as the press is stroking. This Stroke Speed will be used to calibrate the
Motor (Drive Speed). If the Input SPM Cal # parameter is set to 0, the Motor Speed (Drive Speed)
at the bottom of the screen will be 0. Calibration numbers between 0 and 4095 can be entered for
the Input SPM Cal #. Enter calibration numbers by trial and error until the Motor Speed agrees with
Stroke Speed. To do this press the CHANGE SETTING softkey with Input SPM Cal # selected and
enter the calibration #. Do not use the ENTER CAL. MODE softkey for the Input SPM Cal #. The
ENTER CAL. MODE softkey is used only when calibrating Output SPM calibration numbers
where the OmniLink is used to set press stroking speed.
8. Adjust the variable speed drive till the Stroke Speed display at the top of the screen indicates the
minimum stroking speed at which you will operate. If the Motor Speed Reading at the bottom of the
display is within 1 or 2 SPM of the Stroke Speed displayed at the top of the screen at the minimum
SPM stop here, you are finished. If not, it will be necessary to enter small numbers (start with the
number 5) for the SPM Input Offset parameter, gradually entering greater numbers until the Motor
Speed Reading equals Stroke Speed at the minimum SPM.
9. Return the press to the highest stroking speed and refine the Input SPM Cal # to make Drive Speed
again agree with Stroke Speed if necessary.
Section 4.2.2.3 Calibrating Variable Speed Drive Input SPM When Output Without Recall or
Output With Recall is Selected for Speed Mode
When either Output Without Recall or Output With Recall is selected for Speed Mode, the analog
Output SPM signal from the OmniLink to the variable speed drive that sets drive speed must be
calibrated and drive adjustments must be made so that the Drive SPM will actually track the speed
settings entered by use of the OmniLink II Operator Terminal. This calibration/adjustment procedure,
described in Section 4.2.2.4 must be performed first, before calibrating Input SPM, so that the
Operator Terminal can be used to set the drive speeds required in the Input SPM calibration procedure.
Once the analog Output SPM from OmniLink to variable speed drive is calibrated follow the procedure
of Section 4.2.2.2 to calibrate the Input SPM. In step 2 of the procedure, adjust drive speed by pressing
the MOTOR SPEED softkey on the Speed/Load Configuration menu to take you to the motor speed
adjustment screen and enter the desired speed. You will return to the Speed/Load Configuration menu
when the EXIT softkey is pressed once speed is set.
Section 4.2.2.4 Calibrating the Analog Output SPM Signal to Give Correct Drive Speed
If either Output Without Recall or Output With Recall is selected for Speed Mode, the analog Output
SPM signal from the OmniLink to the variable speed drive (see Section 2.3.7.2) that sets drive speed
must be calibrated and drive adjustments must be made so that the Drive SPM will actually track the
speed settings entered by use of the OmniLink II Operator Terminal. The calibration adjustment
procedure is as follows:
1. Go to Section 4.2.4.1 of this manual and configure Stroking Speed to be displayed in the top area of
the operator terminal display “When in a Production Mode”.
