Power-up Mode
This parameter defines the mode which determines the default Running
Value when power
is initially applied to the MDP.
• Mode 1: Default to Zero
When in this mode, the unit will default to zero (display units).
• Mode 2: Default to Power-Up Value
When in this mode, the unit will default to the Power-up Value,
parameter 19.
• Mode 3: Default to Previously Running Value
When in this mode, the unit will default to the previous running value
before power was removed.
NOTE: A previous running value must have been active for at
least 3 seconds to be recalled after power has been disconnected
and reapplied.
Front Panel
DoubleClick Routing
This Parameter determines what happens if the user “Double-Clicks” the
Enter Button (two button presses quickly) on the front panel of the GSD8
(does not apply to GSD8-240-5C).
• Mode 0: DoubleClick Ignored
When in this mode, DoubleClicking on the Enter Button will have no
effect.
• Mode 1: Route DoubleClick to Inhibit
When in this mode, Double-Clicking on the Enter Button when the
drive is “running” will place the Drive in Inhibit, obeying the “acel/decel
rules” found in Parameter 42. Additionally, if the S2 and/or UIN1 inputs
are set up to provide Inhibit control, they are active as well, with the
following rules. Either the DoubleClick and/or S2/UIN1 can cause the
control to go into Inhibit, but both the DoubleClick AND S2/UIN1 have
to be “negated” (set to allow the control to “run”) before the control
will exit “Inhibit” mode and begin to “run” normally again. Note that
the DoubleClick action works as a “toggle”, so the operation could be
somewhat confusing if S2/UIN1 are “routed” to the Inhibit, along with
the DoubleClick, but this behavior is necessary for “safety” reasons.
• Mode 2: Route DoubleClick to EStop
Same as Mode 1, but DoubleClick is Routed to the E-Stop function.
• Mode 3: Route DoubleClick to Jog1
Same as Mode 1, but DoubleClick is Routed to the Jog1 function,
causing the control to temporarily run at the Target Speed in
Parameter 36. See, also, Parameter 36.
• Mode 4: Route DoubleClick to Jog2
Same as Mode 1, but DoubleClick is Routed to the Jog2 function,
causing the control to temporarily run at the Target Speed in
Parameter 41. See, also, Parameter 41.
• Mode 5: Auto/Manual 4-20mA Card
Same as Mode 1, but DoubleClick switches the drive from manual to
auto or vice versa and in manual mode the front keypad has control.
The Auto/Man Annunciator indicates what mode the control is
operating.
19
Power-up Value
When Power-up Mode is set to 2, this parameter will designate the
default display value at power-up in display units.

Display and Control/PID Setup Parameters
20
Display Minimum
This Parameter defines the lower end of the display range. This is the
value which limits how low the user is able to scroll the displayed value in
Running Mode. In Rate and Time modes, this value is set in engineering
units. In Follower Mode, this is set in percentage (actually, 10ths of
percentage) of the master rate. For example, in Follower Mode, a Target
of 150 represents 15.0 percent of the master rate.
21
Display Maximum
This Parameter defines the upper end of the display range. This is the
value which limits how high the user is able to scroll the displayed
value in Running Mode. In Rate and Time modes, this value is set in
engineering units. In Follower Mode, this is set in percentage (actually,
10ths of percentage) of the master rate. For example, in Follower Mode,
a Target of 1250 represents 125.0 percent of the master rate.
