6 Control signal connection
6.1 Control signals using a single-ended signal common
anode connection, as show n below:
Note
www.jmc-motion.com 0755-26509689
When VCC is 5V, R shorted;
:
When VCC is 12V, R is 1K, more than 0.125W resistance;
VCC is 24V, R is 2K, 0.125W greater resistance;
Above resistance must be connected to the control signal terminal.
