Step 7: (Optional) Connect the Encoder Signals
If your motor includes an encoder, complete the following steps to connect the encoder to the
NI 951x terminal block:
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 37-pin terminal block as indicated in Table 1.
4. Insulate any unused wires.
Step 8 : Connect the NI SMD-7620/7621 to AC Power
Note
Do not apply power until after you complete Step 11: Power on the Drive and
Verify Connections .
Complete the following steps to connect the NI SMD-7620/7621 to AC power.
1.
Connect an AC input cable to the line, neutral, and protective earth connectors as shown in
Figure 5.
2. (Optional) Install a fuse on the AC input line as shown. The SMD-7620 contains an internal
8 A fast acting fuse. The SMD-7621 contains an internal 3.5 A fast acting fuse. If an
external fuse is desired, National Instruments recommends a 6 A fast acting fuse for the
SMD-7620 and a 3 A fast acting fuse for the SMD-7621 version.
3. (Optional) If your application requires EMC compliance, install a Corcom 6ET1 line filter
in series with the AC input as shown.
