5-1-3 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.

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.

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 100ms.

0
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 (D at a 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".

(3) Control signal output (Data No. 80 to 87)
A hexadecimal display is converted into a decimal and output. The method of calculating the
magnification is the same as (2). The status cannot be output for each bit, so output the status for
all 16 bits.
(Example) Orientation indexing control
With orientation indexing control, the following operations of the "Control output 4" can be
observed as shown on the right:
bit4: Orientation completed
bit7: Indexing positioning completed
Note that the weight of the D/A output differs for each bit.
