When Changing Input Signal Allocations (Pn50A = n.1)
The following four signals are assigned to CN1-40 to CN1-46 on the I/O signal connector: /C-
SEL (Control Selection), /SPD-A and /SPD-B (Internal Set Speed Selection) signals, and /SPD-
D (Motor Direction) signal.
The control method is switched by turning the /C-SEL signal ON and OFF.
Type Signal Connector Pin No.
Input /C-SEL Must be allocated.
Note: You must allocate the /C-SEL signal to use it. Use Pn50C = n.X (/C-SEL (Control Selection Input) Signal
Allocation) to allocate the signal to a connector pin. Refer to the following section for details.
6.1.2 Output Signal Allocations on page 6-6
The operating method for internal set speed control (i.e., the /C-SEL signal is OFF) is given
below.

Note: You must allocate the /SPD-D, /SPD-A, and /SPD-B signals to use them. You can use the following parame-
ters to allocate the signal to a terminal.
• Pn50C = n.X (/SPD-D (Motor Direction) Signal Allocation)
• Pn50C = n.X (/SPD-A (Internal Set Speed Selection Input) Signal Allocation)
• Pn50C = n.X (/SPD-B (Internal Set Speed Selection Input) Signal Allocation)
