NOTE! A counterbalance pressure that is far too low or far too high during any shut height
adjustment may place excessive load on the shut height adjust motor and may even
stall the motor. This condition can also occur with non-automatic motorized slide
adjust systems. If the automatic slide adjust doesn’t see slide adjust movement within
two seconds of a command to move, it will stop its command to move and generate
the Fault message “Slide Did Not Move”.
IMPORTANT! Automatic movement will be terminated if the ESTOP button, “JOG UP”
softkey, “JOG DN” softkey, or “CANCEL AUTO ADJUST” softkey is
pressed while the slide is moving automatically. Automatic movement will
pause if the slide adjust switch is turned off. It will resume when the slide
adjust switch is turned back on.
same direction every time. Note that a slide setpoint of 00.000 (used to store a job that will not
overwrite the previous slide setpoint on recall), will prohibit automatic adjustment. Automatic
movement is subject to the following conditions:
a) The slide adjust switch must be on.
b) The press must be stopped.
c) The press must be at the top of the stroke.
d) The hydraulic overload on the press, if present, must not be tripped.
e) The Link Master Control (LMC) relay must be engaged.
f) There must be no faults in the slide system and the counterbalance system, if present.
g) The auto adjust sequence for the slide will not start until the counterbalance system, if present, is
at least up to its pressure setpoint. If the correct pressure setpoint for the counterbalance has
been entered, this will ensure that the counterbalance has taken up any clearances in the slide
connection system to increase accuracy of shut height adjustment. When the slide adjust system
waits for the counterbalance system to finish adjusting to its pressure setpoint, the status
message of the slide adjust system will be “Waiting for Cntr-Bal”.
Section 5.1.3 Manual Slide Movement
As noted in the section explaining the softkeys in the slide screen, the slide may be manually moved by
pressing the “JOG UP” and “JOG DN” softkeys. Note that the jog keys will only appear when the
editing cursor is on a slide adjust setpoint. These keys will work regardless of whether the slide system
is on, off, or in manual mode. Note, however, that these keys will not override the mechanical up and
down limit switches in the slide. In addition, these keys will not allow movement beyond the electronic
limits entered in the configuration screen for the slide unless the slide system is “OFF”.
