Example of an Input Circuit
Note:
• Always use twisted pair cables for noise control.
• Recommended variable resistor: Model 25HP-10B manufactured by Sakae Tsushin Kogyo Co.,
Ltd.
Speed Reference Inputs
Refer to Section 5.2.1.
Using the /P-CON Signal
The function of the input signal /P-CON varies with the setting applied to Pn000.1.
Note: The /P-CON signal function switches automatically when Pn50A.0 is set to 0.
