7.1 Gear
This section describes the gear operation and the parameters required to use a gear.
7.1.1 Operation
Relation between the number of pulses outputted from the synchronous encoder or
virtual servomotor and the output module is adjusted by parameter setting of the
encoder resolution of servomotor, the gear ratio in consideration of the deceleration
ratio for machine system etc. and rotation direction.
The gear operation is shown below.
(1) The gear transmits the number of pulses which applied the gear ratio set in the
gear parameter to the travel value (number of pulses) of drive module (virtual
servomotor, synchronous encoder) to the output axis.

(2) The rotation direction of output axis is set in the gear parameters.

Refer to Section 7.1.2 for details of the gear parameters.
7.1.2 Parameters
The gear parameters are shown in Table 7.1 and the parameters shown in this table
are explained in items (1) to (2) below.
Refer to the help of MT Developer2 for the gear parameter setting method.

(Note-1): D800 to D1559 are dedicated devices of the virtual servomotor axis, synchronous encoder axis
and output module "Cam" in the virtual mode. Unused areas of virtual servomotor axis and cam
axis can be used as a user device.
(Note-2): "p" indicates the user setting area points of the Multiple CPU high speed transmission area for
each CPU.
