Jog Your Machine

ATTENTION: You can connect up to four different valves to
your QDC module. Although all four may not directly jog the
ram (screw), clamp, and/or ejector, consider their indirect effect
when setting jog set-output values. Indirectly, they could cause
unexpected machine motion with possible damage to equipment
or injury to personnel.
ATTENTION: A value of 0 entered in your data table does not
necessarily correspond to zero pressure or flow. For an output
configured + 10V dc, an output of 50% corresponds to zero
volts signal output (see graph). Amplifier electronics or spool
offsets may also be designed such that zero volts signal input
does not result in no flow or pressure. Please consult your valve
and amplifier specifications for more details.
