Solve CP1H R88D Servo Motor Controller

I work around a CP1H R88D servo with a pulse output 0 problem. All power settings are standard, except for the electronic gear ratio. The example is the Handbook of 2000 pulses per revolution motor set.
Fine adjustment of the drive car (one horizontal spindle).

I have the move to Omron (power) function block in the CP1H.
The distance between the CP1H and the servo is about 6 m (2 m). The drive is a Panasonic with brake and encoder (not absolute).


Two cases:
1. 2000 pulses is not a revolution engine, only about 3 / 4 2000 pulses also not equal to 2000 forward pulse times (by a significant amount).
2. The highest speed I can use and still move the actuator 100, although I keep hearing that the CP1H is capable of more. The CP1H seems not the problem. When ordered with a speed of more than 100, the power simply ignore the incoming pulse.

I’ve been through all CP1H/R88D manual and found no answers. Has anyone successfully ran a similar sytem? Anyone have a hint of things to look for?
The manuals never a PNP output to the PLC station in pulse mode. It seems that the manuals are to be desired. I found three departments, which called into question. Well, I’m looking forward to implement the same system with an absolute encoder - should be a breeze - right!
