5.3.7 Electronic Gears
It is necessary to adjust the electric gear to convert from the
c
ommand movement value sent from CC-Link
master unit to the travel distance (
smallest unit
is 1[μm] (0.001[mm]) of electrical actuator.
See
“LECSC Operation Manual (Simplified Edition)”,section 5.3.4 for the recommended values for electronic
gears for each actuator model.
Please configure the electronic gear values according to the customer application.
