at which the press will stroke in that mode. On variable speed presses that have high maximum stroking
speeds for the Continuous mode, the stroking speeds in Inch and Single Stroke may be limited to prevent
excessive clutch and brake wear.

Figure 5.6 Machine Speed
Configuration
Section 5.2.13.1 Maximum Strokes/Minute
This parameter also appears in the Machine Parameters screen and can also be programmed in that screen.
See Section 5.2.5. This parameter is used to scale the analog input of flywheel speed to the R/D board for
variable speed presses and its value equals a full scale input to the A/D converter. The minimum resolution
of flywheel speed is equal to this speed divided by 255. The parameter is also used in combination with the
motion filter to determine the length of time that loss of motion can exist during the stroke without causing
a stop condition (see Section 5.2.6). This value is limited to between 10 and 920 rpm. Speed parameters
are rounded to the nearest resolvable number when entered into the press control. The maximum
strokes/minute value entered should be set slightly greater than the actual high speed for which the variable
speed drive is adjusted.
Section 5.2.13.2 Fixed Inch Spm
This parameter is used to configure the press control to stroke at a fixed speed in Inch and Timed Inch
modes. The example shown in Figure 5.6 describes a press that has a maximum stroking speed of 400 spm
but has been configured to Inch at a fixed speed of 50 spm. Each time Inch or Timed Inch mode is selected,
the analog output of the press control will command the drive to run at 50 spm. If a fixed Inch speed is not
desired, a programmed setting of 0000 will turn this feature off and the press control will base inch speed on
the maximum single stroke spm (Section 5.2.13.3). If turned off in the example (Figure 5.6), the press could
inched at any speed setting up to the maximum single stroke limit (100 spm).
Section 5.2.13.3 Max Single Spm
This parameter is used to set a maximum stroking speed for single stroking modes (any mode that
automatically stops at the end of each stroke). These modes include Single Stroke, Setup/Stop Time Test,
