[Data type] Word axis
[Unit of data] 0.01 sec
–1
[Valid data range] 0 to 32767
Set the servo loop gain of the servo axis that interpolates with Cs contour
control axis on each spindle gear (5th group)
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.
