B–63090EN/02
174
(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] 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, 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
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.
Minimum clamp speed of the spindle motor
Set value =
× 4095
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.
