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 IQ area (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" (VS type) 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 software OT selection/Positive software OT
detection/Negative software OT detection position".
