ADJUSTABLE FEATURESSX TRANSISTOR CONTROLS Page 34April 1999FUNCTION 13 FIELD RAMP UP RATE WHILE INREGENERATIVE BRAKING MODE(Push 13)Important Note: This function is used to optimize motor andcontrol performance and this setting will be determined byGE and OEM engineers at the time of vehicle development.This setting must not be changed by field personnel withoutthe permission of the OEM.FUNCTION 14 INTERNAL RESISTANCECOMPENSATION( Push 14 )This function is used when the Battery Discharge Indicatoris present. Adjustment of this function will improve theaccuracy of the BDI. In order to determine this setting, thevoltage drop of the battery under load must first becalculated by the following method:1. Record open circuit voltage (Vo) by measuring thevoltage at the control positive and negative powerterminals.2. Load the traction motor to 100 amps in 1A and record thevoltage (VL) at the control positive and negative powerterminals.3. Calculate voltage drop (VDrop) as follows:VDrop = VO - VL4. Use the table below to determine the appropriate settingusing the calculated VDrop as a reference.INTERNAL RESISTANCE COMPENSATIONTABLESetting VDrop Setting VDrop2 11.44 17 1.343 7.60 18 1.274 5.72 19 1.205 4.57 20 1.146 3.81 21 1.097 3.27 22 1.048 2.86 23 0.999 2.54 24 0.9510 2.28 25 0.9111 2.08 26 0.8812 1.90 27 0.8513 1.76 28 0.8214 1.63 29 0.7915 1.52 30 0.7616 1.43 31 0.74FUNCTION 15 BATTERY VOLTS(Push l5)This function allows for the adjustment of voltage range forcontrols equipped with the Battery Discharge Indicationfunction. In order for the BDI to operate properly, thesetting as shown in the table must be entered:Battery Volts Set Units24 volts Between 0 and 3136 volts Between 32 and 4448 volts Between 45 and 6936/48 volts Between 184 and 250No BDI Between 251 and 255FUNCTION 16 FIELD RAMP DOWN RATE WHILEIN REGENERATIVE BRAKING MODE(Push CONT 1)Important Note: This function is used to optimize motor andcontrol performance and this setting will be determined byGE and OEM engineers at the time of vehicle development.This setting must not be changed by field personnel withoutthe permission of the OEM.FUNCTION 17 JOYSTICK TIMER( Push CONT 2 )This function allows for the adjustment of the delay timefrom the point at which a direction is selected to actualvehicle movement.Range 1.0 to 25.5 secondsSetting Between 0 and 255Resolution 0.1 seconds per set unitExample Setting of 2 = 0.2 secondsFUNCTION 18 ARMATURE CURRENT RAMP UP RATEWHILE IN REGENERATIVE BRAKINGMODE( Push CONT 3 )Important Note: This function is used to optimize motor andcontrol performance and this setting will be determined byGE and OEM engineers at the time of vehicle development.This setting must not be changed by field personnel withoutthe permission of the OEM.FUNCTION 19 NOT APPLICABLEThis function is not applicable to this type of control andshould not be adjusted.FUNCTION 20 NOT APPLICABLEThis function is not applicable to this type of control andshould not be adjusted.The following functions have function numbers larger than thenumbers on the Handset keyboard. To access these functions,push the CONT key and the number shown in the instructions atthe same time. THE SEAT SWITCH MUST BE OPEN.
