External Feedback Pulse Phase-Z Setting
3327 hex
Setting
range
Size
Set to enable or disable phase-Z disconnection detection when an external encoder with a 90°
phase difference output is used.
Explanation of Set Values
Set value
Hybrid Following Error Counter Overflow Level
3328 hex
Setting
range
Size
Set the allowable difference (feedback pulse error) between the motor (encoder) position and load
(external encoder) position in command units.
Refer to 6-6 Fully-closed Control on page 6-12.
Hybrid Following Error Counter Reset
3329 hex
Setting
range
9
Size
The feedback pulse error is reset every time the motor rotates for the amount set by the Hybrid
Following Error Counter Reset (3329 hex). This can be used for applications where feedback
pulse error accumulates due to slippage.
Refer to 6-6 Fully-closed Control on page 6-12.
Ensure that an appropriate value is set to the Hybrid Following Error Counter Reset (3329 hex),
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 sufficient safety measures. This includes mounting limit sensors.
