1. LIST OF ALARMS
1.3 Servo Alarms
I - 20
S02 INIT PARAM ERR ∆∆∆∆
xis name
larm No. (parameter No.)
Servo : Axis name
Spindle : "S", "T"
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. Details Remedy
2201 - 2265
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
parameters and correct them.
2269
The CNC setting maximum rapid traverse
rate value is incorrect.
Check the setting of related parameter
"#2001 rapid" and turn the power ON again.
2271
The CNC setting maximum cutting speed
setting value is incorrect.
Check the setting of related parameter
"#2002 clamp" and turn the power ON again.
2281 - 2300
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
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
Parameters for absolute position detection
are set to ON while other than an absolute
position detector is connected.
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-
side detector) or dual feedback control
function is an option.
Check that all the related parameters are
specified correctly.
sv025:MTYP/pen
sv017:SPEC/dfbx
2304
No servo option is found.
The SHG control function is an option.
Check that all the related parameters are
specified correctly.
sv057:SHGC
sv058:SHGCsp
2305
No servo option is found.
The adaptive filtering function is an option.
Check that all the related parameters are
specified correctly.
sv027:SSF1/aflt
2306
The servo option is not available.
The MP scale absolute position function is
an option.
Check that the related parameter is specified
correctly.
s017:SPEC
2308
The valid/invalid setting of the 4th or 5th
notch filter is changed from the initial
setting.
Check the following parameter setting status.
s087:FHz4
s088:FHz5
3201 – 3584
Parameter error
A parameter value not within the tolerable
range was set. The alarm No. is the No. of
the spindle parameter where the error
occurred.
Confirm the spindle parameter for the No.
displayed as an error.
