Faulty Encoder Reading from SDC2130

Hi,
I have two issues with my Encoder settings and count value.
1. Counter1 is not showing the encoder reading correctly(should show 90000 counts per cycle, but show different values that not even close to that value each time)
2. Encoder is having 22500 PPR, but i can only type 5000 (max) in Roborun+ utility.
I will be very thankful for your help.

Hi,
I am here sending you the link to encoder data sheet
www.zhengkemotor.com/product/product60.html





Encoder was mounted in the back side of motor, which having 1:45 gear ratio. Encoder is giving 500PPR and when it multiply by gear ratio should be give 22500 pulses and count value in counter should be 22500*4 which is 90000. I verified this count value by directly reading encoder from micro controller. It was giving me the correct count value.when try to use SDC2130 counter it gives faulty reading(like 1000, 3000, etc) which is not even close to 90000.

motor data sheet also attach with related picture.thank you
