Wiring Examples Section 3-3
CW/CCW Pulse Output and Pulse plus Direction Output
Using a Motor Driver with 24-V DC Photocoupler Inputs
Note The terms in parentheses are for pulse + direction outputs.
Using a Motor Driver with 5-V DC Photocoupler Inputs
Connection Example 1
Note The terms in parentheses are for Pulse + Direction outputs.
In this example, the 24-V DC power supply is used for the motor driver with 5-
V inputs. Verify that the NC Unit's output current will not damage the motor
driver's input circuits. Also verify that the inputs turn ON properly.
Check that the 1.6-k
Ω
resistors have sufficient power derating.
