Abstract
PURPOSE: To prevent a machine from being out of order, a drive motor from seizing, or from any other trouble by treating individually in proportin to their causes in judgment of causes why the macnine were unable to follow its command value from a counter value of an error counter.
CONSTITUTION: When count value B of an error counter 3 is less than first and second settled values (A) and C, the count value B is supplied to a drive motor 7, and a timer 18 remains in reset condition. When the count value B has gone up beyond the first settled value (A), the settled value (A) is supplied to the drive motor 7. Further, when the count value B has gone up beyond the second settled value C, at the same time as the timer 18 is set, command is made a momentary stop with error limit signals given to an arithmetic control part 2. Even if a settled time would have passed, unless the count value B does not come under the secnd settled value C, servo abnormality displaying signals are given their output through the timer 18.
