value
0 External encoder feedback pulse count direction not reversed
1 External encoder feedback pulse count direction reversed
Pn327
External Feedback Pulse Phase-Z Setting
Setting
0 or 1
range
Set to enable or disable phase-Z disconnection detection when a 90° phase difference output type
external encoder is used.

value
0 Phase-Z disconnection detection enabled
1 Phase-Z disconnection detection disabled
Pn328
Internal/External Feedback Pulse Error Counter Overflow Level
Setting
27
1 to 2
range
 Set the allowable difference (feedback pulse error) between the motor (encoder) position and load
(external encoder) position in command units.
Pn329
Internal/External Feedback Pulse Error Counter Reset
Setting
0 to 100
range
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 applications 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. When the set value is extremely small, the protective function may not work to
prevent any erroneous operation due to improper connection of the external encoder.
Take sufficient care to ensure safety.
