Power on the Drive and Verify Connections
.
1.
Connect the V+ terminal from the 24 V power supply to one of the two V

sup
input for the NI 9512 on
pin 14 and pin 22.
2.
Connect the V- terminal from the 24 V power supply to one of the COM terminals on the
37-pin terminal block. The 37-pin terminal block provides COM on pins 3, 5, 8, 17, 24,
