(6) Parameter setting relating to the system in which the MZ sensor or
BZ sensor is used.
When rigid tapping is to be performed using a MZ sensor or BZ
sensor, or when a built–in motor with a BZ sensor is being used, the
following parameters must be specified.
(a) Set the following parameter according to the pulse number of the
MZ sensor or BZ sensor.

(b) Set the following parameters when the gear ratio between the
spindle and the motor (the sensor) is not 1: 1. (except for
orientation based on the external one–rotation signal)
i) Set the parameter “Doing the rigid tapping by using the
arbitrary rear ratio (command) in the built–in MZ sensor”.

iii) Set the parameter “the arbitrary gear ratio between the
spindle and the position coder” according to each CNC.
D Set the gear teeth number of the spindle side.
Each parameter is selected according to the gear selection signal.
