8.9

IntAGain

      

This value determines how rapidly the over-ride output will ramp down 
when  the  current  from  the  battery  pack  exceeds  the  programmed 
current limit. Too low of a value will result in considerable overshooting 
of  the  set  point  current,  while  too  large  of  a  gain  will  cause  the 
controller  to  oscillate  above  and  below  the  limit.  The  range  of 
allowable values is from 0 to 999.

                   

8.10

IntVGain

      

Default = 800

This  value  determines  how  rapidly  the  over-ride  output  signal  will 
scale  down  when  the  pack  voltage  falls  below  the  set  low  voltage 
cutout. The range of allowable values is from 0 to 999, and the scaling 
is arbitrary.

      

8.11

ITermMax

   

Default = 3.79V

This  puts  an  upper  limit  on  how  high  the  throttle  over-ride  will  drift 
upwards when none of the limit values are being exceeded. Ideally this 
value  is  set  to  the  voltage  that  is  considered  full  throttle  by  the 
controller. For hall effect throttles, full power occurs at about 4V, and 
limiting the ITerm to this value will speed up the response time of the 
limiting  features.  Allowable  values  are  from  0  to  4.99V. 

   

8.12

ITermMin

   

Default = 0.0V

This value imposes a lower bound on how low the throttle over-ride 
can  drift  downwards  when  one  of  the  limiting  values  is  being 
exceeded. By preventing the over-ride signal from going all the way to 
0V,  you  can  decrease  the  recovery  time  for  the  signal  to  go  back 
upwards. Range is from 0 to 4.99V, and must be less than ItermMax.          

8.13

Max Throttle

  

   

Default = 4.99V

This value puts a maximum cap on the throttle output signal. It can be 
used to simulate a lower speed motor by simply clamping the throttle 
signal to a value between 0 to 5V.   Be aware that the majority of hall 
effect throttles only operate from 1V to 4V, and so the desired setting to 
reduce the speed would fall in this range (less the diode voltage drop). 
 

 

Default = 300
