TOMATECH AUTOMATION
BIT2,
BIT1 and BIT0 (DIR5, DIR4, DIRY, DIRZ, DIRX separately corresponds to 5th, 4th, Y, Z, X)
of bit
parameter No.008.
The manual move direction can be set by BIT4,BIT3,BIT2,BIT1, BIT0 (5VAL, 4VAL, YVAL,
ZVAL,
XVAL separately corresponds to 5th, 4th, Y, Z, X movement key) of bit parameter No.175.
4.3 Gear Ratio Adjustment
№015～№016 can be modified for electronic gear ratio adjustment to meet the various
mechanical transmission ratios when the machine travel distance is not consistent with
the
displacement distance displayed by the CNC.

Ⅲ Connection
CMR: Code multiplier coefficient (data parameter No.015)
CMD: Code frequency division coefficient (data parameter No.016)
C: Motor’ s encoder lines
α : Pulse volume, motor rotation angle for a pulse
L: Screw lead
δ: Current min. input code unit of CNC
ZM : gear teeth number of lead screw
ZD: gear teeth number of motor
Example: if gear teeth number of lead is 50, gear teeth number of motor is 30, motor
encoder
lines C=5000 lines, screw lead is 4mm, CNC’s current increment is 0.1μ.
The electronic gear ratio of X axis is:
