Mitsubishi Electric · MELSEC iQ-R Motion Controller
This minor error occurs when the number of control axes configured per controller exceeds the maximum allowed limit for the current SSCNET operation cycle. It indicates a configuration mismatch that prevents proper system operation.
Click steps to track your progress.
Set the operation cycle to 0.444ms or more if controlling 3 to 4 axes.
Set the operation cycle to 0.888ms or more if controlling 5 axes or more.
For SSCNETIII, verify the axis select rotary switch of the servo amplifier is set to '0 to 3' for 0.222ms operation or '0 to 7' for 0.444ms operation to ensure servo amplifiers are recognized.
Ensure 'Not used' is set via DIP switch for any unused axes with MR-J5W- B or MR-J4W- B servo amplifiers to reduce the count.
