Linear Motor and Third-Party Motor
The encoder / linear scale settings include pulse type, sine wave type, and communication type.
Refer to the following for more details.

Encoder / Linear Scale Setting (pulse type)
11
PM.004 Main encoder resolution: input the linear scale resolution after frequency quadrupling
(unit: 0.001 µm/pulse). For example, if the linear scale resolution is 1 μm/pulse, then PM.004 =
1000.
PM.045 Linear motor pole pitch: you can find this value in the linear motor catalog, or you can
select a linear motor model from the database and the value is automatically filled in; if you are
using a third-party linear motor or the linear motor is not yet created in Delta's database, you
must input the value manually. If the set value is incorrect, AL051 is triggered.
When the settings are complete, click Write and then click Next.
