Initial communication with the absolute position
linear scale was not possible.
An error in the communication with the detector
was detected in the absolute position detection
system using the OHA type detector and serial
absolute position linear scale.
There is an error in the serial data format from
the OHA-type detector or serial-type absolute
position linear scale.
When the NC power was turned on, the absolute
position counter could not be set because
absolute position data had been varied.
An excessive deviation in the feedback amount
from the motor end detector and MP scale was
detected in the MP scale absolute position
detection system.
An error was detected in the offset data read in
when the CNC power was turned ON in the MP
scale absolute position detection system.
An error was detected in the multi-rotation
counter with the serial type detector. The
absolute position was not compensated.
The battery voltage supplied to the absolute
position detector dropped.
Eighty percent of the regenerative alarm was
detected.
Eighty percent of the overload 1 alarm level has
been detected. (An overload 1 alarm may occur
if this operation continues as it.)
The value in the absolute position counter is
illegal. The absolute position must be initially set.
The set parameter exceeds the setting range.
This invalid parameter is ignored and the value
before the invalid parameter was set remains
valid.
The control axis is being removed.
An emergency stop command was input from
NC.
Regeneration at the limit of the power supply
regeneration capacity is occurring frequently.
An instantaneous power failure for 25ms
occurred. (The main circuit voltage has not
dropped, so an alarm does not occur.)
An external emergency stop input signal was
input. (24V is not applied on the CN23
connector.)
Eighty percent of the over-regeneration alarm
was reached.
