4.DESCRIPTION OF PARAMETERS B-64120EN/01
- 196 -
NOTE
This parameter needs not to be set for serial
spindles.
3731
Compensation value for the offset voltage of the analog output of the spindle
speed
[Data type] Word
[Unit of data] Velo
[Valid data range] -1024 to+1024
Set compensation value for the offset voltage of the analog output of
the spindle speed.
-8191 × Offset voltage (V)
Set value=
12.5
[Adjustment method]
(1) Assign standard value 0 to the parameter.
(2) Specify the spindle speed so that the analog output of the spindle
speed is 0.
(3) Measure the output voltage.
(4) Assign the value obtained by the following equation to parameter
No.3731.
-8191 × Offset voltage (V)
Set value=
12.5
(5) After setting the parameter, specify the spindle speed so that the
analog output of the spindle speed is 0. Confirm that the output
voltage is 0V.
NOTE
This parameter usually need not to be set for serial
spindles (Set to 0).
