(c) Pulse Command Input Interface Circuit(IO3):<br />
Suggesting to use the input method of Line Driver to send the pulse <strong>com</strong>mand. The maximum input <strong>com</strong>mand<br />
frequency is 500kpps. Using the input method of Open Collector will cause the decrease of input <strong>com</strong>mand<br />
frequency, the maximum input <strong>com</strong>mand frequency is 200kpps. The servo provides only 24V power, and other<br />
power should be prepared. Adverse polarity of power will cause the servo damage. The maximum of External<br />
power (Vcc) is 24V limited. Input current is about 8~15mA. Please refer to the examples below to select<br />
resistance. Please refer to 5-4-1 to check pulse input <strong>com</strong>mand timing.<br />
