9. SPINDLE SPEED FUNCTION
1082
NOTE
θ represents the basic angular diplacement set in
pamrameter No. 4963.
4963 M code for specifying a spindle positioning angle
[Data type] Word
[Unit of data] deg
[Valid data range] 1 to 60
This parameter sets a basic angular displacement used for semi–fixed
angle positioning using M codes.
4964 Number of M codes for specifying a spindle positioning angle
[Data type] Byte
[Unit of data] Integer
[Valid data range] 0, 1 to 255
This parameter sets the number of M codes used for semi–fixed angle
positioning using M codes.
As many M codes as the number specified in this parameter, starting with
the M code specified in parameter No. 4962, are used to specify
semi–fixed angle positioning.
Let a be the value of parameter No. 4962, and let b be the value of
parameter No. 4964. That is, M codes from Ma to M (a+b–1) are used
for semi–fixed angle positioning.
WARNING
Make sure that M codes from Ma to M (a+b–1) do not
duplicate other M codes.
NOTE
1 This parameter is valid when bit 6 (ESI) of parameter No.
4950=1.
2 Setting this parameter to 0 has the same effect as setting 6.
That is, M code from Ma to M (a+5) are used for half–fixed
angle positioning.
4970 Servo loop gain of the spindle
[Data type] Word
[Unit of data] 0.01 sec
–1
[Valid data range] 1 to 9999
Set the servo loop gain of the spindle in the spindle positioning mode.
