Omron CP1H Motion

Hi All,

I am using Omron CP1H, trying to move a motor, I am using the built in pulse output to generate pulse, the pulse output method is "pulse+direction" (NOT CW/CCW).

For now, I can always move the motor in ONLY 1 direction. Any hints that can help me to move the motor in a reverse direction?

Thanks.

Since the motor drive and wiring also may be the reason, you better post your code here.

thanks for your reply, Sergie.
Yes, you were right, The setting in the driver caused the problem.
Thanks.

However, I am having few other questions after I got the motor moving in both directions.
1. I see a lot of "PV"'s in the programming manual. What does "PV" stand for?
2. I am used to developing PC-based programming for the motion, in which I can keep track of my position using the built-in API.
For CP1H, is there any way I can keep track of my current position (means how many pulses I have sent out, etc.)

Thanks.

Hello Chuckheng,

PV = Present Value

The PV (Present Value) is the motion axis actual coordinate.
However, it must be preset by INI instruction. Until that no absolute moves are possible and on relative moves the PV resets on each move start.

Motion Commands Intro

The CJ1H uses similar motion commands as the CJ1M.
