ADJUSTABLE FEATURESSX TRANSISTOR CONTROLS Page 36May 2000FUNCTION 20 HILL CLIMBING SPEED LIMITThis function allows for the adjustment of the speed limitwhen the vehicle is on such an incline that the tilt sensorswitch is open.Range 0 to 20Set 0 to 20Resolution 1 pulse per sampleExample: Setting of 5 = 5 pulses persample rateFUNCTION 21 NOT APPLICABLEThis function is not applicable to this type of control andshould not be adjusted.FUNCTION 22 NOT APPLICABLEThis function is not applicable to this type of control andshould not be adjusted.FUNCTION 23 ERROR COMPENSATION(Push CONT 8)This function is used to reduce the ripple in the field currentdue to the interaction between the motor field design andthe digital field current regulation circuit. The value for thisfunction will be defined to the vehicle manufacturer by theGE application engineer.Important Note: The 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 24 FIELD WEAKENING START(Push CONT 9)This function allows for setting the armature current atwhich minimum field current will be achieved.Range 0 to 414 ampsSetting 0 to 255Resolution 1.625 per set unitExample Setting of 20 = 32.5 ampsFUNCTION 25 MONITOR( Push CONT 10)This function allows the monitoring of certain controlfunctions by looking directly at the RAM of themicroprocessor. Because absolute memory locations needto be known, this function should not be used withoutdetailed instructions from the GE application engineer.To ensure optimum operation of the control, this functionmust be left with zero stored in this register.FUNCTION 26 RATIO( Push CONT 11)This function sets the ratio between armature and fieldcurrent when transitioning from minimum field to maximumfield current. The setting represents the quantity of fieldcurrent changed for each 1 amp of armature currentchanged.Max Max Resolution ExampleFld Ref Change Set Per unit value If set at 520 .24 0 to 10 0.024 amps 0.12 amps30 .24 0 to 10 0.024 amps 0.12 amps40 .27 0 to 10 0.027 amps 0.135 amps50 .48 0 to 10 0.048 amps 0.24 amps60 .48 0 to 10 0.048 amps 0.24 ampsFUNCTION 27 NOT APPLICABLEThis function is not applicable to this type of control andshould not be adjusted.FUNCTION 28 STORED STATUS CODE COUNTPOINTER( Push CONT 13)This register contains the location of the last stored statuscode recorded of the 16 stored status codes. These storedstatus codes have caused a PMT controller shutdownand/or disruption of normal vehicle operation.To determine which stored status code was the last onerecorded, read the number stored in Function 28. Using theMemory Map for your logic card, match the "stored statuscode pointer number" [the number shown in (bold italics)in the HS (Handset) number column] on the memory map,with the number obtained from Function 28. This will be thelast stored status code recorded.Note: When scrolling through the stored status coderegister, the register always starts at status code 1 andscrolls to status code 16. Instructions for scrolling theregister are in section 5.3.2 of this instruction booklet.Note: The following functions have function numberslarger than the numbers on the Handset keyboard. Toaccess these functions, push the CONT key and thenumber shown in the following instructions at the sametime. The seat switch must be closed.
