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.

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.

filter
Set the filter time constant of load meter output.
When "0" is set, a filter time constant is set to 100ms.

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).

(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".
