greater than the default in case greater speeds are required to complete a cycle. To cause the crankshaft
to rotate at other than the initial default speed, the speed control knob must be rotated completely
counterclockwise, then rotated back clockwise to the desired speed setting. If the Jog button is depressed
within three seconds of setting the speed control knob, the crankshaft will rotate at the speed defined by
the position of the speed control knob. The new speed setting will remain active for a maximum of three
seconds after the Jog button is released, or until the crankshaft completes the cycle. If the cycle is not
complete and the Jog button is again pressed within three seconds from its release, the crankshaft will
rotate at the speed defined by the position of the speed control knob. Failure to push the Jog button within
the three seconds of its release will cause the crankshaft jog speed to revert back to the initial minimum
default value. After the Jog button is released, the speed control knob can be rotated in either direction to
increase or reduce the crankshaft jog speed, but Jog button must be activated again within three seconds
of the release or the speed will revert back to minimum default speed. The speed control knob can be
reset as many times as desired.
The ram may drift downward if the Jog button is released in mid-stroke.
C. Jog (With Guards Disabled) Mode
(Figure 10)
Since Machine -4 does not employ safety interlock switches in the guard doors, this section does not apply to
Machine -4.
The foot pedal will NOT initiate cycling in this mode.
To avoid personal injury, be very careful of moving mechanisms when jogging the machine with the guards open.
This mode allows maintenance and setup personnel to slowly rotate the crankshaft with the guard door
open. To activate this mode, turn “off” power, and open the guard door. Turn the power back “on” and,
immediately after the machine ready and guard disable indicators flash “on”, press and hold the Jog
button. The guard disable indicator will flash at a rate of two flashes per second, indicating that the guard
has been disabled. Pressing the Jog button will rotate the crankshaft at a reduced rate until the Jog button
is released or the crankshaft completes one cycle.
Pressing the Jog button causes the crankshaft to be rotated at a default–reduced speed in the forward
direction until the Jog button is released or the crankshaft completes the cycle. If the Jog button is
released in mid–cycle and then pressed again, the crankshaft will continue to rotate in the forward
direction at the default reduced speed. If the machine does not complete the cycle, see “Adjusting the
Speed Control Knob,” below.
Holding the Jog button for more than five seconds and not completing the cycle may cause the machine to
“err.” To clear the error, “power down” the machine, clear the problem area, and then “power up” the
machine. Another method of clearing an error is to hold down the foot pedal until the green status indicator
stops flashing. If the motor is stalled, it may be necessary to manually cycle the machine to the home
position. See the CAUTION and DANGER statements above for manual cycling.
Adjusting the Speed Control Knob
The default speed of the crankshaft in the Jog Mode is set to a minimum initial value which is
not defined
by the initial position of the speed control knob. Adjusting the speed upwards enables jogging at speeds
greater than the default in case greater speeds are required to complete a cycle. To cause the crankshaft
to rotate at other than the initial default speed, the speed control knob must be rotated completely
counterclockwise, then rotated back clockwise to the desired speed setting. If the Jog button is depressed
within three seconds of setting the speed control knob, the crankshaft will rotate at the speed defined by
