I am using fatek PLC model 32MNT2. I need to interface a high speed maximum 5000 rpm magnetic disc stepper motor model DM50 Diamatec and with the shaft of stepper motor there is a 500ppr incremental disc encoder 9100A attached. I am using HSCTR function for taking encoder pulses. My aim is to find the RPM of stepper motor. I tried everything even, the code given in the manual but, there is too much variation in the RPM. For example, if the RPM of stepper is 3000 then the calculated RPM by the PLC will be varying between 2500 to 4000. I tried by changing time duration for 1ms to 5seconds but nothing works. Please, help me in this regard. I would be grateful.
