5. Parameters
5.1 Parameter Settings Required for Operation
Parameters can be set or changed using the teaching pendant or PC software.
After a parameter has been changed, the new setting will become effective once a “software reset” is performed
using the teaching pendant or PC software or the power is reconnected.
5.1.1 Basic Settings
The parameters that must be set before the actuator can be operated are explained below.
(The following parameters are all you need to set, if the actuator performs only positioning operation.)
(1) Electronic gear
User parameter Nos. 65/66, “Electronic gear numerator/denominator”
Name Symbol Unit Input range
Default setting
(reference)
Electronic gear
numerator
CNUM - 1 to 4096 2048
Electronic gear
denominator
CDEN - 1 to 4096 125
These parameters are used to determine the unit travel distance of the actuator per each command pulse-train
input pulse.
Unit travel distance for linear axis = Minimum travel unit (1, 0.1, 0.01 mm, etc.) per pulse
Unit travel distance for rotational axis = Minimum travel unit (1, 0.1, 0.01 deg, etc.) per pulse
 Electronic-gear calculation formula
Linear axis
Rotational axis
Reference
The actuator speed is calculated by the formula below:
Speed = Unit travel distance x Input pulse frequency (Hz)
Take note that setting the unit travel distance too small may prevent the actuator from reaching the maximum
speed in certain conditions.
