8A
Detector converting
unit 2:
Communication
error
An error was detected in the communication with the serial output
linear scale of the unit MDS-B-HR in a servo system. In a spindle
system, an error was detected in the communication with
MDS-B-PJEX.
8B
Detector converting
unit 2: Automatic
tuning error
An abnormal signal was detected from PLG in automatic PLG tuning.
8C
Detector converting
unit 2: Judgment
error
The detector type outside the specification was designated in
MDS-B-PJEX.
8D
Detector converting
unit 2: CPU error
A CPU error was detected in the unit MDS-B-HR in a servo system,
or in the unit MDS-B-PJEX in a spindle system.
8E
Detector converting
unit 2: Data error
A data error was detected in the unit MDS-B-HR.
S02 INIT PARAM ERR
ΔΔΔΔ
Axis name
Alarm No. (parameter No.)
Servo : Axis name
Spindle : “S”, “T”, “M”, “N”
An error was found in the parameters transmitted from the controller to the drive unit when the power was
turned ON.
Remove the cause of the alarm, and then reset the alarm by turning the controller power OFF once.
Alarm No.

Remedy
2201 - 2264
The servo parameter setting data is illegal.
The alarm No. is the No. of the servo
parameter where the error occurred.
Check the descriptions for the appropriate
servo parameters and correct them.
2301
The number of constants to be used in the
following functions is too large:
• Electronic gears
• Position loop gain
• Speed feedback conversion
Check that all the related parameters are
specified correctly.
sv001:PC1, sv002:PC2, sv003:PGN1
sv018:PIT, sv019:RNG1, sv020:RNG2
2302
High-speed serial incremental detector
Parameters for absolute position detection
are set to ON during OSE104 and OSE105
connection.
Set the parameters for absolute position
detection to OFF.
To detect an absolute position, replace the
incremental specification detector with an
absolute position detector.
Check that all the related parameters are
specified correctly.
sv017:SPEC, sv025:MTYP
2303
No servo option is found.
The closed loop (including the ball screw-
end detector) or dual feedback control is an
optional function.
Check that all the related parameters are
specified correctly.
sv025:MTYP/pen
sv017:SPEC/dfbx
