IS810N-INT Series Servo System User Manual (Brief) Chapter 4 Wiring
Value of resistor R1 is calculated according to the following formula:
Table 4-18 Recommended R1 resistance values
VCC Voltage R1 Resistance Value R1 Power
24 V 2.4 kΩ 0.5 W
12 V 1.5 kΩ 0.5 W
The following gures show wrong wiring examples.
Wrong connection 1: The current-limit resistor is not connected, resulting in terminal damages.
Wrong connection 2: Terminals are not correctly connected, resulting in terminal damages.
