4. DESCRIPTION OF PARAMETERS
113
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 compesation value for the offset voltage of the analog output of the
spindle speed.
Set value =–8191 Offset voltage (V)/12.5
(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.
Set value=
12.5
–8191 × Offset voltage (V)
(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 need not to be set for serial spindles.
3732
The spindle speed during spindle orientation or the spindle motor speed during
spindle gear shift
[Data type] 2word
[Valid data range] 0 to 20000
Set the spindle speed during spindle orientation or the spindle motor
speed during gear shift.
When GST, #1 of parameter 3705, is set to 0, set the spindle speed during
spindle orientation in rpm.
When GST, #1 of parameter 3705, is set to 1, set the spindle motor speed
during spindle gear shift calculated from the following formula.
For a serial spindle
Set value =
× 16383
Spindle motor speed during spindle gear shift
Maximum spindle motor speed
For an analog spindle
Set value =
× 4095
Spindle motor speed during spindle gear shift
Maximum spindle motor speed
