ZERO POINT INITIALIZATION
— ERROR COMPLETED nTH
AXIS
[Function]
This signal is output when initialization is not possible during the marked point alignment method of
the absolute position detection system.
[Operation]
This signal turns ON when the initialization is not possible at the rising edge of the "Zero point
initialization start (ZSTn)" signal.
This signal is invalidated in the following cases:
• During emergency stop
• During reset
• When "Zero point initialization start (ZSTn)" signal is turned ON before the "Zero point initialization
mode (AZSn)"
• When grid has not been passed even once after the power has been turned ON. (Depends on the
detector type)
[Related signals]
(1) Zero point initialization completed (ZSFn: X44A)
(2) In zero point initialization (X44C)
(3) Zero point initialization incomplete (X44D)
(4) Zero point initialization mode (AZSn: Y452)
(5) Zero point initialization start (ZSTn: Y453)
