MotionControl Error once in a blue moon

[Krr]

Hi everyone!

I have annoying problem with one of the servo motors on a machine. I am using NX1P2 PLC with 8 servo motors 1S. Two of them are Gered with MC_GearIn. One of the servo is the master the other one is the slave. Once in a blue moon the master one fire an error (Fault Code: 0x64580000  Fault Description: "Motor position deviation exceeds allowable range"). And the error appear when the motors are not moving (changeover or maintenance). I couldn't replicate the error on my testing machine so i do not know what cause the alarm. The only way to reset this error is to Home the two motors with MC_Home. I have to mention: this is happening only when the motors are configured in LinearMode never happened in RotaryMode.

Any help will be appreciated.

What is the allowable deviation in your Drive configuration? Have you traced the commanded vs actual to see how much you are deviating?
