need help on OMRON servo drive

[wiwie 0]

I want to control the servo drives R88D-GT08H with PLC CP1H-Y20DT-D, PLC is a 100KHz pulse output and the servo drives max 500kpps, what does this mean for the PLC pulse is Hertz and the drive pulse is pps, how many Hz which should be given to the drive to motor Continues speed 2500rpm.

The hertz is equivalent to cycles per second.

By default, that drive requires 10,000 pulses per revolution. 2500 rpm is 41.66667 revs / s. So, you would need to command the servo at a pulse rate of 416,667 pulses / second (or 416,667 Hz) to get it to spin at 2500 rpm. However, most of the time, you scale the input to the drive to a particular unit (inches, mm, degrees, etc). So, this would change if units have been set for that drive. Check Pn48 and Pn4B to see what the ratio is for the drive in question.
