Step 4: Connect The Logic Power Supply To The Akd Servo Drive - National Instruments PCI-7354 Getting Started

1. Connect the cable X9 DSUB connector to the AKD servo drive X9 DSUB connector.
2. Connect the cable X8 10-pin connector to the AKD servo drive X8 10-pin connector.
Note You can use the X7 I/O connector for additional I/O but it is not used for
connection to the NI UMI.
Step 4: Connect the Logic Power Supply to the AKD
Servo Drive
Using a UMI-7772/74
Note You may use the same +24 V power supply to power both the UMI-7772/74
and the AKD drive. However, ensure that the power supply is capable of delivering
enough current for the application. If you require more power, connect a separate
+24 V power supply to the AKD drive X1 connector as described in this section.
1. Connect the +24 V power supply (+) terminal to the +24V connection on the X1 3-pin
connector.
2. Connect the +24 V power supply return (–) terminal to the GND connection on the X1 3-pin
connector. The X1 connector is connected to the UMI-7772/74 cable by the GND wire. Do
not remove this wire when connecting the +24 V power supply GND wire.
3. Connect the cable X1 3-pin connector to the AKD servo drive X1 3-pin connector.
4. Connect the STO input to the +24 V input, or connect it to the output of an external safety
relay or security control.
Note The STO input must be powered by +24V for proper drive operation. If you
need to use the STO functionality connect the STO terminal and GND terminal to the
output of a safety relay or security control. The safety relay must comply with the
requirements of the SIL 2 according to IEC 61800-5-2, PL d according to
ISO 13849-1, or Category 3 according to EN-954. Refer to the AKD Installation
Manual for more information.
