Connecting Peripheral Devices
Section 2-7
The following example illustrates how to combine these parameters.
Example
In this example it is assumed that the default settings are in effect for the
machinery, and that positioning moves in the minus (–) direction with plus (+)
position command values from the MC Unit.
In this case, by setting the parameters according to setting method 3 or 4,
positioning can be moved in the plus (+) direction by plus (+) position com-
mand values from the MC Unit. The
●
marks in the following table indicate the
set values.
When using an absolute encoder-type motor, use either setting method 1 or 3.
If either of the other two setting methods is used, the present value cannot be
correctly re-established following a power outage.
With a W-series Servo Driver, bit 0 of Cn-02 corresponds to digit number 0 of
Pn000.
With a G-series Servo Driver, bit 0 of CN-02 corresponds to Pn51. (Set Pn46
to 0.)
