8.8 Operating Using Speed Control with an Internally Set Speed
• Internally Set Speed Selection
This function allows speed control operation by externally selecting an input signal from among three servo-
motor speed settings made in advance with parameters in the SERVOPACK. The speed control operations
within the three settings are valid. There is no need for an external speed or pulse generator.
8.8.1 Setting Parameters
Note: The maximum speed of servomotor is used whenever a speed settings for the Pn301 to Pn303
exceed the maximum speed.
8.8.2 Input Signal Settings
The following input signals are used to switch the operating speed.

 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
