Getting Started with NI SMD-7620/7621 and NI 73xx
Step 3: Connect the Drive Ena
b
le Signal to the UMI-7764
Complete the following steps to connect the Drive Enable signal, which controls the enable
function of the drive:
1.
Connect the X3/EN- terminal (pin 6) to the Motion I/O terminal block INHOUT1 terminal.
2.
Connect the X3/EN+ terminal (pin 5) to the Motion I/O +5V terminal.
Step 4: (Optional) Connect the Drive Fault Signal to the UMI-7764
Complete the following optional steps to connect the drive fault signal to monitor the
SMD-7620/7621 for faults.
1.
Connect the Y1+ terminal to the Motion I/O terminal block INHIN1 terminal.
2.
Connect the Y1- terminal to the Motion I/O terminal block GND terminal.
Step 5: (Optional) Connect the Encoder Signals to the UMI-7764
If your motor includes an encoder, complete the following steps to connect the encoder signals
to the UMI-7764.
1.
Connect one end of the encoder cable to the encoder.
2.
Cut the 15-pin DSUB connector off of the other end of the cable and expose the encoder
wires.
3.
Connect the encoder wires to the UM-7764 Motion I/O terminal block as indicated in
Table 2.
4.
Insulate any unused wires.
