z Using a Motor Drive with 5-VDC Photocoupler Input
• Connection Example 1
Note The terms in parentheses are for pulse + direction outputs.
In this example, the 24-VDC power supply is used for the motor drive with 5-V inputs. Verify that the
Position Control Unit's output current will not damage the motor drive's input circuits. Also verify that
the inputs turn ON properly.
Check that the 1.6-kΩ resistors have sufficient power derating.
• Connection Example 2
Note The terms in parentheses are for pulse + direction outputs.
