7 TRANSMISSION MODULE
(1) Gear ratio
(a) The number of pulses transmitted to the output axis through 1 pulse
outputted from the drive module by the gear module is set in the gear ratio.
(b) The gear ratio is based on the settings for the input axis side tooth count (GI)
and output axis side tooth count (GO).
Gear ratio
(2) Rotation direction of output axis
(a) The rotation direction of the output axis forward the rotation direction of the
input axis is set.
(b) There are two types for rotation directions of the output axis: forward and
reverse.
1) Forward
When the input axis rotates to the address increase direction, the output
axis also rotates to the address increase direction.
Drive module
2) Reverse
When the input axis rotates to the address increase direction, the output
axis rotates to the address decrease direction.

POINT
If the gear ratio is set indirectly, the timing that the gear ratio set in Motion SFC
program becomes valid is shown below.
(1) When the real mode is switched to virtual mode.
(2) When the current value of the drive module is changed in the virtual mode.
