9. SPINDLE SPEED FUNCTION
455
(5)After setting the parameters, command “0”, confirm that the output 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, is set to 0, this is the spindle speed
during spindle orientation in min
–1
.
When GST, #1 of parameter 3705, is set to 1, this is 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
NOTE
If the function of constant surface speed control or bit 4
(GTT) of parameter No. 3706 is specified, this parameter is
invalid.
3736
Maximum clamp speed of the spindle motor
[Data type] Word
[Valid data range] 0 to 4095
Set the maximum clamp speed of the spindle motor.
Set value =
×4095
Maximum clamp speed of the spindle motor
Maximum spindle motor speed
