Then data parameter No.015X (CMRX) =5, No.016X (CMDX) =12; No.015Z(CMRZ) =5,
No.016Z
(CMDZ) =6.
If the electronic gear ratio numerator is more than the denominator, the allowed CNC max.
speed
will decrease. For example: the data parameter No.015Z (CMRZ) =2, No.016Z (CMDZ)
=1, so the
allowed Z axis max. speed is 12000mm/min.
If the electronic gear ratio numerator is not equal to the denominator, the allowed CNC
positioning precision may decrease. For example: the data parameter No.015Z(CMRZ)
=1,
No.016Z(CMDZ) =5, so the pulse is not output as the input increment is 0.0004, but a
pulse is output
when the input increment is 0.0005.
