7.1.4 Purpose of Position Check Operation
If the absolute number of rotation detected at power supply ON does not
match the data stored in the absolute encoder the last time the power
supply was turned OFF, an alarm is issued when the drive panel power is
turned ON.
There are two possible causes of this alarm:
• Error in the encoder system
• The manipulator was moved after the power supply was turned OFF.
If there is an error with the encoder system, the manipulator may stall
when playback is started. If the absolute data allowable range error alarm
has occurred, playback and test runs will not function and the position
must be checked.
7.1.5 Procedure after the Alarm
WARNING
•
Be aware of safety hazards when performing the position
confirmation of the specified point.
Abnormality of the encoder system may be the cause of the alarm. The
manipulator may operate in an unexpected manner, and there is a risk
of damage to equipment or injury to personnel.
