8.8.2 Input Signal Settings
The following input signals are used to switch the operating speed.
8.8.3 Operating Using an Internally Set Speed
Use ON/OFF combinations of the following input signals to operate with the internally set speeds.
Note: Signal OFF = High level; Signal ON = Low level
Control Mode Switching
When Pn000.1 = 4, 5, or 6, and either /P-CL (/SPD-A) or /N-CL (SPD-B) is OFF (high level), the control
mode will switch.
Example:
When Pn000.1=5: Internally set speed selection ⇔ Position control (pulse train)

 Input Signal Selection
The following two types of operation can be performed using the internally set speeds:
• Operation with the /P-CON, /P-CL, and /N-CL input signals (pins allocated in factory setting)
• Operation with the /SPD-D, /SPD-A, and /SPD-B input signals
/SPD-D, /SPD-A, and /SPD-B input signals must be allocated with parameter Pn50C. Refer to 7.3.2 Input Circuit Signal
