8.8 Operating Using Speed Control with an Internally Set Speed8.8.2 Input Signal SettingsThe following input signals are used to switch the operating speed.TypeSignalNameConnector PinNumber8.8.3 Operating Using an Internally Set SpeedUse ON/OFF combinations of the following input signals to operate with the internally set speeds.Note: Signal OFF = High level; Signal ON = Low levelMeaningInput /P-CON CN1-41 Switches the servomotor rotation direction.(/SPD-D) Must be allocatedInput /P-CL CN1-45 Selects the internally set speed.(/SPD-A) Must be allocatedInput /N-CL CN1-46 Selects the internally set speed.(/SPD-B) Must be allocated• Input Signal SelectionThe 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.
