OT REL is the abbreviation of Over-Travel Release (to release over-travel). There is one limit switch on each of the two
ends of the servo axis stroke to prevent damage due to servo mechanism collision. Over travel takes place every time the
servo mechanism reaches the stroke limit. When over travel of this controller occurs, it is regarded as an emergency stop,
and the message "EMERGENCY STOP OR OVER TRAVEL" will be displayed on the screen with indicator lights flashing. The
servo mechanism must be examined for over travel.
If over travel is confirmed, it will be switched to hand wheel (MPG) operation mode or continuous jog mode (JOG) before
pressing this key (with indicator lights turned on). The controller will temporarily ignore the emergency situation caused
by over travel and allow the operator to move the servo axis back within the stroke via the hand wheel or axis arrow keys;
the (OT REL) can be released for the system to resume stroke inspection. If everything has been restored to normal status,
"Not ready" will be replaced by "Ready" to indicate that normal operation can be resumed. If other alert messages are
also appearing, the <Reset> key must be pressed before restoring to normal operation. Please pay attention to the
direction and speed of movement while moving back the servo mechanism in order to avoid collision.
(Note) when the "Not ready" status suddenly shows up, it could be caused by over travel, so please include over travel as
one of the items to be inspected.
2.7 Emergency stop (EMG-STOP)
In case of a dangerous or emergency situation, this button can be pressed to stop all operation. The method for releasing
this button is to rotate the button along the direction of the arrow on the button, then the button will automatically
bounce up.
When this button is pressed, the system will be in a state of not ready (the status field will show "Not ready"). For
absolute safety, the driving power in the electrical control box will be disconnected. It must be confirmed that the cause
of malfunction has been resolved before clearing the emergency stop. After clearing the emergency stop, the reference
point return operation should be executed again in order to ensure that the coordinate position is correct.
Please note: As soon as the emergency stop is pressed, reference point return must be performed after each clear, yet the absolute
reference point is not affected by this limitation.
