4
Place a multimeter between L1 and L2. It should read either
110 VAC or 230 VAC, depending on the input line voltage
used.
5
Turn off MCB Q7, Q8 and Q9.
6
Check the resistance between motor windings, which should
read as follows:
Ma and Mb = 2 ohms
Ma and Mc = 2 ohms
Mb and Mc = 2 ohms
If the resistance is greater, it means there is a wire break
somewhere.
7
Note that the E-Stop should be off.
8
If everything is OK, close the cover to the Kollmorgen drives
and turn on Q7, Q8 and Q9 (if Z-axis is present).
9
Make sure that the connector highlighted below is connected
to C3 on the Kollmorgen drive. This connector relays the
machine IO information (such as positive and negative
limits) for the axis. Both drives should have this connector.
For the wiring, refer to the
Electrical Drawing document.
