  • Page 5: Ironhorse Gsda-Dp-D Motor Speed Control General Information

    IronHorse GSDA-DP-D Motor Speed Control General Information The GSDA-DP-D motor speed control is a compact, microprocessor-based unit capable of being either field or factory configured for a number of motion control needs. The control is designed around a velocity form PID algorithm, and provides a DC speedpot signal to an external drive. A flexible open-loop mode is also available for applications where using a speed pickup is not practical or desired.

The GSDA-PU2E is designed for indoor use and the GSDA-PU2R for wash down or outdoor use. Both provide one, ten or twenty pulses per revolution. Their design provides for ease of installation in otherwise difficult to reach areas.

  • Page 12 overshoot is eliminated and/or the desired upper response time is reached. To adjust D: (Parameter 28): D can be used to dampen the effect of P. By making D too large, the response time of the control can be reduced, so keep D as small as possible on non-regenerative controls. Generally speaking, the proportion of P-I-D seems to be more critical than the individual values, i.e..

  • Page 23: Gsda-Dp-D Software Parameter Descriptions

    GSDA-DP-D Software Parameter Descriptions Parameter Parameter Name Description When Parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running Mode and, depending on the value of Parameter 12, will display Exit to Running Mode the running (Target) or actual (Tach) value. This should be selected once changes to Parameters are completed.
  • Page 24 Parameter Parameter Name Description This Parameter selects what the GSDA-DP-D will show on its display during Run Mode. Note that it can “toggle” between whatever the Display Mode is set to and its “opposite” by briefly pressing and releasing the ENTER button. For example, if this Parameter is set to 1 (Target Speed/Time), pressing the ENTER button will briefly show the Actual (Tach) Display (and illuminate the “Tach”...
  • Page 25 Parameter Parameter Name Description When Power-up Mode is set to 2, this Parameter will designate the default Power-up Value display value at power-up in the user’s desired units of measure (“engineering units”), e.g. RPM, GPM, FPM, etc. This Parameter determines what happens if the user “Double-Clicks” the Enter Button (two button presses quickly) on the front panel of the GSDA-DP-D.
  • Page 26 Parameter Parameter Name Description This Parameter controls two behaviors in the GSDA-DP-D, Low-Speed “Gain- Tracking”, and Ultra-Low-Speed Control Mode (“gearbox” mode). When set to a value of 1 (or 3), this parameter automatically (and proportionally) reduces the “gain” of the PID values when the Target Speed (in RPMs) is less than 200.
  • Page 27 Parameter Parameter Name Description Somewhat analogous to a “Min. Speed” control on analog motor speed controls, this sets a “minimum output” that is applied as soon as the Target Speed is above Zero RPM. Careful use of this setting can help with “stiction” (the tendency for motors to require a bit more “oomph”...
  • Page 28 Parameter Parameter Name Description Signal Input #2 Setup Parameters This Parameter determines the operating mode of signal input 2 (S2). • Mode 1: Disabled (Follower Mode) The S2 input is inactive. This is the required setting for Follower Mode. • Mode 2: Emergency Stop When S2 High (Not Wired To Common) When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the GSDA-DP-D will enter emergency-stop mode.
  • Page 29 Parameter Parameter Name Description User Input #1 (UIN1) Setup Parameters This Parameter determines the operating mode of user input 1 (UIN1). • Mode 1: Disabled The UIN1 input is inactive. • Mode 2: Emergency Stop When UIN1 High (Not Wired To Common) When the UIN1 input is at an electrically high (+5V) state or allowed to float disconnected, the GSDA-DP-D will enter emergency-stop mode.
  • Page 30 Parameter Parameter Name Description This Parameter determines the accel/decel profile of the GSDA-DP-D when it is going into and out of “Inhibit” Mode. There are 4 possible settings: • Mode 0: No Accel/Decel When going into Inhibit, the GSDA-DP-D will immediately shut off its output, disregarding any Decel setting, and when coming out of Inhibit, the GSDA-DP-D will immediately return to its Target Speed, disregarding any Accel setting.
  • Page 31 Parameter Parameter Name Description This setting determines which actions will cause an active alarm to be silenced or reset. • Mode 1: No Silencing, Reset On ENTER Button Press In this mode, an active alarm cannot be silenced. Once the alarm condition ceases to exist, however, the ENTER button may be pressed to cause a manual reset.
  • Page 32 Parameter Parameter Name Description Alarm Output #2 Setup Parameters This Parameter, in conjunction with Parameters 71 & 72, defines which conditions will result in the Alarm 2 output being activated. The function is Alarm 2 Logical “OR” Activation that of a Logical “OR”ing of the selected Drive Condition Flags. A setting of Conditions (Flags Table 1) zero defeats this “OR”...
  • Page 33 Parameter Parameter Name Description This Parameter defines the number of seconds the output should be disabled Alarm 2 Pulse off Time during the ‘off’ phase of an active pulsing alarm’s output. This setting determines how many pulses are outputted when the alarm is Alarm 2 Pulse Count activated and is configured in pulse output style.
  • Page 34 Parameter Parameter Name Description When set to the desired Modular Bus Slot number (100, 200, 500) and the ENTER button is pressed, the Default settings for that Modular Bus card’s Parameters will be copied to the selected Slot’s “partition” in the non-volatile storage of the GSDA-DP-D.
  • Page 35 Parameter Parameter Name Description Current Time (In Hours) This displays the current time in hours that the unit has been running. This option can be used to extend the maintenance time of the device when the system is not working as hard as it could. Scaling allows the timer to be scaled when the motor is running below a pre-set value.

  • Page 36: Application Examples

    Application Examples SCADA-driven Pump Controller with 4-20mA I/O, plus”Fault” and “Run” Relay Outputs Description: A GSDA-DP-D drive (with GSDA-AI-A8 installed) operating a waste pump control receives a target speed setting from the SCADA system, 4-20 mA output. The GSDA-DP-D drive will display the actual pump rate in liters per minute, and will continuously report the pump’s actual flow rate to the SCADA system using the GSDA-AI-A8’s 4-20 mA output.

  • Page 38 using the “inverters” (Parameter 51 in the case of Alarm1). In negative logic, a positive logic “AND” is actually a negative logic “OR”. So, to set up that “but NOT if this OR this OR this” condition, we simply set both the Inverters (Parameter 51 for Alarm1) as well as the AND conditions (Parameter 52 for Alarm1) to the BCD sum of the flags we wish to consider.
