A position detector error may occur after replacement and adjustment of the
servo motor or timing belt. When this happens, execute the following restoring
operation.
1)
Execute "[2] HOME operation."
2)
Execute "[3] ZEROP operation." At this time, the contents in the parameter
file (i.e., home position data within one (1) full turn of motor) are updated.
Rewriting of the data into the system disk is necessary.
3)
Make sure that the error has been reset, referring to the error display.
4)
In the "[2] HOME operation" and "[3] ZEROP operation", some error may be
caused according to the adjusting method. Re-teaching of the teach points
may be required under some circumstances.
After resetting the error, effect an emergency stop, manually move each axis to
the motion limit and make sure that a soft stroke limit error generates. If the
mechanical interference is caused before generation of the soft stroke limit error,
repeat the restoring operation in the manner described above.
(2)
When a position detection error has occurred during normal operation with
the mechanical connection position unchanged:
A position detector error may occur after battery voltage drop, or battery or cable
replacement. When this happens, execute the following restoring operation.
1)
Execute "[1] Encoder error reset operation."
2)
Make sure that the error has been reset, referring to the error display.
After resetting the error, effect an emergency stop, manually move each axis to
