Maintenance function
 If two or more alarms occur simultaneously, alarms are output in the priority specified in the table
above.
 The life warning is for the capacitors in the main circuit inside the servo amplifier and the cooling
fan (OR condition).

+OT detection: Sequence output signal (Reference value 38)

-OT detection: Sequence output signal (Reference value 39)

The state of over-travel (±OT) is output.
 Function
The corresponding + OT or - OT detection sequence output is turned on while the +OT or -OT
sequence input signal terminal remains turned off.
 Parameter setting
To assign the positive or negative OT detection to a sequence output terminal, specify the
corresponding value ("38" or "39") to the output terminal function setting parameter.
 Relevant description
(1) OT detection
The signal is turned on when the servomotor detects the OT signal in either the positive or
negative direction. For details, refer to "Over-travel in positive direction [+OT]: Sequence input
signal (Reference value 7), Over-travel in negative direction [-OT]: Sequence input signal
(Reference value 8)".
(2) Software OT
Set PA2_25 (software OT selection) at "1" to allow movement in the position range between
(PA2_26 (Positive software OT detection position)) and (PA2_27 (Negative software OT detection
position)).
For details, refer to 4.4.2 "PA2_25 to 27 Position operation type, software OT detection position".
