IronHorse GSD8 DC Drives User Manual – 1st Ed. Rev. A – 10/15/2019
Run Mode
is the default display mode when power is applied. The GSD8 drive will spend the majority
of its time in this mode. In Run Mode, the display shows the Target or Actual (“Tach”) speed value
in the user-defined Engineering Units format for rate, time, or percentage of Master if in “Follower”
mode. The GSD8 drive control algorithm will continuously adjust motor speed to achieve the Target
value. In Run mode, the Up and Down buttons increase or decrease the displayed target within the
display minimum and maximum limits. Depending on the alarm configuration, these buttons may
also serve as alarm-silence or alarm-reset buttons. For example, displays for rate, time, and follower
operating modes could be 13.60, 45:30, and 1000, respectively.
Additionally, the GSD8-240-5C-D, 10C-10 and 10N4X when equipped with the GSDA-AI-A8 option, have
an “Auto/Manual” Annunciator which displays a “solid” light if the source of the Target Setting comes
from the 4-20mA input (“Auto”), or a “blinking” light if the Target Setting comes from the “front panel”
Target setting (“Manual”).
Parameter Mode
can be entered by pressing and holding the Enter button down for three seconds.
Once in Parameter Mode, the “Parm” LED will illuminate. The display will indicate the currently
selected parameter number for editing purposes. Pressing the Up or Down button will increase or
decrease the selected parameter number on the display. Although the parameter numbers are in
numerical order, some numbers are skipped. These numbers represent reserved Parameters that are
not yet implemented and are not displayed.
Further, parameter numbers above 999 are actually located on the option card(s) that are installed
in the GSD8 Drive. The numbering scheme is the “slot number (100, 200 or 500) times 10, plus the
parameter number. Once the desired parameter number is displayed, a press of the Enter button will
change the display to Value Mode. So, for example, to view/edit Parameter 20 on an option card in
Slot 200, “Browse” to parameter number 2020 (200 X 10 + 20).
NOTE: When in Parameter Mode, pressing the Enter button with parameter 0 selected will return to
Run Mode. Consult the parameter map for a complete list of GSD8 parameters.
Value Mode
is used to modify the value of the selected parameter. When in Value Mode, the “Valu”
LED will illuminate. Pressing the Up or Down button will increase or decrease the selected parameter’s
value. With the exception of parameter 10, changes in parameter values are processed by the drive as
the value changes and without pressing the Enter button. For example, when adjusting P-I-D settings,
the change in response can be observed “live”, which greatly facilitates the P-I-D “tuning” process.
Once the desired value is showing in the display window, pressing the Enter button again will return to
Parameter-Selection Mode and the new value will be saved in permanent memory. Removing power
from the unit while in Value Mode will result in the specified new value being lost, and the previous
(old) value being used. This can be used as an “undo”, for example, during editing a value that is being
edited in the wrong Parameter.
NOTE: Changes to Parameter 10, Operating Mode, do not take effect until power is removed and re-
applied to the GSD8 drive.
