I/O Signal Allocations
This section describes the I/O signal allocations.
3.3.1 Input Signal Allocations
In most cases, input signals can be used at the factory settings. Input signals can also be allocated as required.
(1) Using Factory Settings
Items in cells with bold lines in the following table are the factory-set signal allocations.
If the control method is changed in Pn000.1, the signals will function as required for the control method.
The factory-set signal allocations will remain unchanged.
When the control method is set to internal set speed control with a contact reference, i.e., when Pn000.1 is set
to 3, signal /P-CON (CN1-16) will function as /SPD-D, signal /P-CL (CN1-26) as /SPD-A, and signal /N-CL
(CN1-12) as /SPD-B.
