4-1 D/A output specifications for spindle drive unit
The spindle drive unit has a function to D/A output each control data. The spindle adjustment data
required to set the spindle parameters matching the machine can be D/A output. The data can be
measured with a hi-corder or oscilloscope, etc.

4-1-3 Setting the output magnification
(1) Meter output (Data No. 0)
With meter output, the output channel is fixed, and the output voltage range is 0 to 10V in the
positive range. Set the magnification with the following parameters. Also, low path filter can be set
on the load meter output.
No. Abbr. Parameter name Details
Setting
range
Standard
SP017 TSP* Maximum motor
speed
Set the maximum spindle motor speed.
When SP249=0, the motor speed will be the motor rotation
speed at the speedometer 10V output.
1 to 32767
(r/min)
6000
SP094 LMAV* Load meter output
filter
Set the filter time constant of load meter output.
When "0" is set, a filter time constant is set to 226ms.

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
full scale adjustment
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).

SP179 LMG*
Load meter output
full scale adjustment
Adjust the load meter full scale.
Adjust so that the fluctuations of the load meter is at the
intended position when "1" is set in SP177(MADJ).
0 to 1000
(1/1000-fold)

SP249 SMO Speedometer speed Set the motor rotation speed when the speedometer 10V is
output.
When set to "0", this parameter becomes the same as SP017
(TSP).

SP250 LMO Load meter voltage Set the voltage when the load meter 120% is output. When set
to "0", this becomes 10V.

(2) Internal data output (Data No. 1 to 13)
Normally, the standard setting value is set for the output magnification (SP255, SP256). When
"0" is set, the magnification will be the same as "256".
