Reading The Position Data From The Absolute Linear Encoder - YASKAWA SGD7S series Product Manual

6.13.4 Reading the Position Data from the Absolute Linear
Encoder
There are two methods that you can use to read the position data from the absolute linear 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 Linear
Encoder
•
When Using the Default I/O Signals (Pn50A = n.
Set 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.

signals (Pn50A = n.

Reading the Position Data from the Absolute Linear Encoder without
Using the SEN Signal
Set Pn50A to n.
Refer to the following sections for details on the parameters.
