This bit is set to 1, AL-81, AL-82, AL-85, AL-86 are checked.
RFCHK2 Specifies whether to detect alarm related to position feedback signal for
thread cutting (AL-46)
0 : Alarm detection disabled.
1 : Alarm detection enabled.
RFCHK3 Function for redetecting the one rotation signal each time position contorl
mode is entered.
0 : The one rotation signal is not detected each time the operating mode
changes.
Once the one rotation signal has been detected, it is not detected again
until the power goes off
1 : The one rotation signal is detected each time the operating mode
changes.

Data unit : (Motor rotation for one rotation of spindle) x100
(When parameter No. 4006#1(GRUNIT) is 1, (motor rotation) x1000)
Data range : 0 to 32767
Standard setting : 100
These parameters set the gear ratio of the spindle motor relative to the
spindle.
When the motor rotates 2.5 times for every rotation of the spindle, for
example, set 250 in the parameter.
A parameter is selected by the CTH1A and CTH2A input signals. The gear
or clutch status must correspond to the status of the CTH1A and CTH2A
input signals.
