15 Alarms and warnings

Cause Action
• The command position exceeded the coordinate control
range (−2,147,483,648 to 2,147,483,647).
• The multi-rotation data for internal encoder coordinates
exceeded the coordinate control range (−32,768 to 32,767).
(This alarm generates when the absolute system function is
used in the position control mode.)
• Set the command position so that the moving range will
remain inside the coordinate control range.
• If this alarm generates inside the coordinate control range,
the multi-rotation data for internal encoder coordinates
exceeds the coordinate control range. Turn off the power,
disconnect the encoder cable, connect it again after approx.
30 seconds, and then turn the power back on.
• The power was turned on for the first time after connecting
the battery.
• No battery is connected, the battery cable is disconnected,
or the battery has been consumed.
• The encoder cable came off.
• The position range error alarm was reset.
(This alarm generates when the absolute system function is
used in the position control mode.)
• Perform position preset.
• Check the battery connection, or replace the battery.
The battery was detected when the absolute function was
disabled in the position control mode.
If the absolute system function is used, enable the absolute
function. If the absolute system function is not used,
disconnect the battery.
No battery was detected or the battery cable was
disconnected when the absolute function was enabled.
Check the connection condition of the battery.
The power was turned on when the resolution set by the
electronic gear and encoder output electronic gear was
outside the specified range.
Set the electronic gear and encoder output electronic gear
correctly, then turn the power back on.
An encoder error was detected during operation. Turn off the power, check the connection between the
encoder and driver, then turn the power back on.
A communication error occurred between the driver and
encoder.
Turn off the power, check the connection between the
encoder and driver, then turn the power back on.
An encoder error was detected when the power was turned
on.
Turn off the power, check the connection between the
encoder and driver, then turn the power back on.
The motor output shaft rotated by 1/40th of a revolution
during the initialization following a power on.
Prevent the motor output shaft from rotating due to an
external force when the power is turned on.
Data stored in the encoder communication circuit was
damaged.
Turn off the power, check the connection between the
encoder and driver, then turn the power back on.
A motor not supported by the driver is connected. Check the driver model and motor model, and use the driver
and motor in the correct combination.
Data stored in the driver was damaged. Initialize the parameters and operation data using the data
setter OPX-2A or the data setting software MEXE02.
