[Caution]
When SBTSTMOm is turned ON without meeting the following conditions, the brake test does not start. When this signal
is turned ON without satisfying (1) to (12) of (Condition), the smart safety observation alarm (V51 0001) occurs.
(Condition)
(1) All part systems are not in automatic operation.
(2) The target axis to be tested is in in-position.
(3) The target axis to be tested is in servo ON state.
(4) The target axis to be tested is not in current limit.
(5) The target axis to be tested is not the slave axis in the synchronous control.
(6) The target axis to be tested is not in superimposition control.
(7) There is no axis which is in arbitrary axis exchange control within the part system to which target axis to be tested
belongs.
(8) There is no axis which is in mixed control within the part system to which target axis to be tested belongs.
(9) The parameter "#51191 SBT_ILIM" (SBT current limit value) of target axis to be tested is not "0".
(10) The parameter "#51193 SBT_FD" (SBT movement command amount) of target axis to be tested is not "0".
(11) The parameter "#51194 SBT_FDRATE" (SBT command speed) of target axis to be tested is not "0".
(12) The reference position establishment signal of target axis to be tested is ON.
(13) The target axis is not in PLC axis mode of NC axis/PLC axis switchover function.

Cont. Signal name
Safety absolute position
A confirm
(control axis)
[Function]
This signal is used to cancel the alarm "Safe absol. posn unestablished" and establish the safety absolute position in SLP/
SCA encoder diagnosis during power OFF.
[Operation]
When the "Safe absol. posn unestablished" alarm is occurring, turning ON this signal will cancel the alarm and bring it to
the safety absolute position established state (the "In safety position establishing" signal is ON.). By establishing the
safety absolute position, the observation with SLP and the signal output with SCA is possible. (SLP/SCA will not operate
while the "Safe absol. posn unestablished" alarm is occurring.)
[Caution]
This alarm is to show that users have checked the correctness of the absolute position. Before turning ON this signal,
manually move the axis to a position where the coordinate values are clear (marked position, reference position, etc.) (in
the case of a relative position detection system, operate the reference position return), then compare the actual position
and the displayed position to confirm the both positions are corresponding.
