9. SPINDLE SPEED FUNCTION
380
[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.
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] Two–word
[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 or spindle gear selection system is T
type, is set to 0, set the spindle speed during spindle orientation in rpm.
When GST, #1 of parameter 3705, is set to 1 or spindle gear selection
system is M type, set the spindle motor speed during spindle gear shift
calculated from the following formula.
Set value =
×16383 (For a serial spindle)
Spindle motor speed during spindle gear shift
Maximum spindle motor speed
Set value =
×4095 (For an analog spindle)
Spindle motor speed during spindle gear shift
Maximum spindle motor speed
3735
Minimum clamp speed of the spindle motor
[Data type] Word
[Valid data range] 0 to 4095
Set the minimum clamp speed of the spindle motor.
Set value =
×4095
Minimum clamp speed of the spindle motor
Maximum spindle motor speed
