When an alarm occurs in the drive unit, this signal outputs the cont ent of the alarm that occu rred in
a combination of 4bit.
Even if the unit is normal, this signal may turn ON for 1 second after the power i s turned ON.

4-3 Adjustment procedures for each control
4-3-1 Basic adjustments
(1) Items to check during trial operation
[1] Directly couple the motor and machine, and check the control status during m achine run-in.
[2] Check that the command speed and actual speed match.
If the speeds do not match, check spindle parameters again.
(Especially check SP017, SP034, SP040 and SP257 to SP384.)
[3] Is the rotation smooth?
[4] Is there any abnormal noise?
[5] Are there any abnormal odors?
[6] Has the bearing temperatu re risen abnormally?
(2) Adjusting the speed meter/load meter
The speed meter/load meter is adjusted when using the display measurement output.
[1] Set "1" in the parameter SP177(MADJ).
[2] Change value in the parameter SP178(SMG) and adjust so that the speed meter displays the
maximum speed.
[3] Change value in the parameter SP179(LMG) and adjust so that the load meter displays the full
scale.
[4] Return the parameter SP177(MADJ) to "0" when the adjustment is completed. Failure to do this
could result in displaying full scale for both meters at all times.

SP177 MADJ* Meter full scale
compulsory output
When carrying out a full-scale adjustment to the speed meter
and load meter, set to "1" here so that the full scale voltage is
output and the adjustment mode is entered. Adjustment is
carried out with SP178(SMG) and SP179(LMG) at this time.
Always return the setting value to "0" when the adjustment is
completed.
0 to 1 0
SP178 SMG* Speed meter output

Adjust the speed meter full scale.
Adjust so that the fluctuations of the speed meter is at the
intended position when "1" is set in SP177(MADJ).

4. Spindle Adjustment
4 - 28
(3) Adjusting the motor (spindle) rotation speed
(a) When using analog input for the speed command
1) When using bipolar input (SE1-SE2 input) for the speed command
[1] Confirm if "0" is set to the parameter SP155(SAtyp) and SP158(Adofs), and "1053" to
SP161(Sgain).
[2] Start the motor by commanding SO(0 rotation comm and) from NC(PC).
[3] Adjust the value of SP158(Adofs) so that the motor(spindle) almost stops.
The motor (spindle) rotation may not be stopped completely even if SP158(Adofs) is adjusted.
[4] Start the motor by inputting S*** from NC(PC).
At this time, S*** equals to the value "maximum spindle speed×0.95" (Motor speed =
S***×(1/gear ratio))
[5] Adjust SP161(Sgain) so that the motor (spindle) rotation speed becomes the speed set in [4]
above.
S command rot. speed
S command rot. speed x (1/gear ratio)
Motor actual rotation speed
Spindle actual rotation speed
SP161(Sgain)
≒1053 x
or
[6] After following all the setting procedures above, change the S command and confirm if the
rotation speed changes ac cordingly.
2) When using unipolar input (OR1-O R2 input) for the speed command
[1] Confirm if "1" is set to the parameter SP155(SAtyp), "262" to SP158(Adofs), and "1147" to
SP161(Sgain).
[2] Start the motor by commanding SO from NC(PC).
[3] Adjust SP158 so that the motor (spindle) is stopped.
Subtract "1" from the value at which the motor (spindle) starts rotating from a stop state, and
then set that value in SP158(Adofs).
(Example)
SP158(Adofs) = "257" : Motor (spindle) stops
SP158(Adofs) = "258" : Motor (spindle) starts rotating
The setting value of SP158(Adofs) = "257"
[4] Start the motor by inputting S*** from NC(PC).
At this time, S*** equals to the value "maximum spindle speed×0.95" (Motor speed =
S***×(1/gear ratio))
[5] Adjust SP161(Sgain) so that the motor (spindle) rotation speed becomes the speed set in [4]
above.
S command rot. speed
S command rot. speed x (1/gear ratio)
Motor actual rotation speed
Spindle actual rotation speed
SP161(Sgain)
≒1147 x
or
[6] After following all the setting procedures above, change the S command and confirm if the
rotation speed changes ac cordingly.
