1.8 Auxiliary Axis Alarms
Details
The absolute position detection
battery voltage dropped.
The regeneration power may
have exceeded the tolerable
range of the built-in regenerative
resistor or external regenerative
option.
The overload alarm 1 could
occur.
There is an error in the absolute
position detector internal data.
The servo ON signal was input
while the main circuit power was
OFF.
The contactor operation is faulty.
Cause
The zero point (reference point)
has not been initialized in the
absolute position system.
The absolute position coordinate
data in the amplifier has been
lost.
The absolute position system
related parameters have been
changed or lost.
Cause
The data in the detector has been
lost.
Battery voltage drop.
Detector cable wire breakage or
looseness.
I - 40
Remedy
• Mount a battery.
• Replace the battery and initialize
the absolute position.
• Lower the positioning frequency.
• Change the regenerative option
to a larger one.
• Lower the load.
• Refer to the items for S03 0050.
• Take countermeasures against
noise.
• Replace the servomotor.
• Turn ON the main circuit power.
Remedy
• Initialize the zero point (reference
point).
• Initialize the zero point (reference
point).
• Correctly set the parameters and
then initialize the zero point
(reference point).
Remedy
• Check the battery and detector
cable and then initialize the zero
point (reference point).
