6.12.4 Reading the Position Data from the Absolute Encoder
There are two methods that you can use to read the position data from the absolute encoder: Using
the SEN (Absolute Data Request) signal and not using the SEN signal.
Setting the Parameter to Specify Using or Not Using the SEN
(Absolute Data Request) Signal
Using the SEN Signal to Read the Position Data from the Absolute
Encoder
•
When Using the Default I/O Signals (Pn50A = n.
The setting of Pn515 = n.
•
Allocating the SEN Signal to CN1-40 to CN1-46 on the I/O Signal Connector (Pn50A = n.
Set Pn515 = n.
Refer to the following section for the procedure to allocate input signals.
