8-4 Analog Control Parameters
Pn327
External Feedback Pulse Phase-Z Setting
Setting
range
 Set to enable or disable the Phase-Z disconnection detection when an external encoder of 90
phase difference output type is used.
Explanation of Set Values
value
Pn328
Internal/External Feedback Pulse Error Counter Overflow Level
Setting
range
 Set the allowable difference (feedback pulse error) between the motor (encoder) position and load
(external encoder) position in command units.
Refer to "5-4 Full Closing Control (P.5-9)".
Pn329
Internal/External Feedback Pulse Error Counter Reset
Setting
range
8
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.
Refer to "5-4 Full Closing Control (P.5-9)".
 Ensure that an appropriate value is set to the Internal/External Feedback Pulse Error Counter
Reset (Pn329), before you use the feedback pulse error counter reset. 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.
 Provide enough safety measures. This includes to mount limit sensors.
