9. SPINDLE SPEED FUNCTION
432
4056 Gear ratio (HIGH)
4057 Gear ratio (MEDIUM HIGH)
4058 Gear ratio (MEDIUM LOW)
4059 Gear ratio (LOW)
[Data type] Word axis
[Unit of data] (Number of motor rotations to one spindle rotation) 100
[Valid data range] 0 to 32767
Set the gear ratio between spindle and AC spindle motor.
NOTE
For which gear ratio is used in actual spindle operation, it
depends on clutch/gear signal (serial spindle) CTH1A,
CTH2A.
4069 Position gain at Cs contour control (High gear)
4070 Position gain at Cs contour control (Medium High gear)
4071 Position gain at Cs contour control (Medium Low gear)
4072 Position gain at Cs contour control (Low gear)
[Data type] Word axis
[Unit of data] 0.01 sec
–1
[Valid data range] 0 to 32767
Set the position gain at Cs contour control.
NOTE
For which position gain is used in actual spindle operation,
it depends on clutch/gear signal (serial spindle) CTH1A,
CTH2A.
4135 Grid shift value at Cs contour control
[Data type] Two–word
[Unit of data] 1 pulse unit (360000 p/rev)
[Valid data range] –360000 to +360000
Set the number of pulses from an issue of one–rotation signal to the
machine zero point in Cs contour control.
