Explanation of Set Values
Explanation of Set Values
 Set the allowable difference (feedback pulse error) between the motor (encoder) position and load
(external scale) position in command units.
The feedback pulse error is reset every time the motor rotates for the amount set by the Internal/
External Feedback Pulse Error Counter Reset (Pn329). This can be used for purposes where
feedback pulse error accumulates due to slippage.
 When using feedback pulse error reset, make sure the feedback pulse error reset setting is set to
a proper value. In the case of an extremely small value, it may not function as a protection against
error operations caused by erroneous connection of external scale.
Take sufficient care to ensure safety.
