Make sure the machine ID key is plugged into the machine or it will not run. Note: Spindle
control machines use a different machine ID key then non-spindle control machines.
Whenever you replace a cable or reroute a cable it is very important to keep the power cables
and logic cables separated from each other. The power cables consist of the (3) 110-volt motor
cables and (2) 110-volt power cables for the pendant, and a coolant pump or solenoid power
cable. The logic cables are used to carry encoder signals between the cable breakout box and
computer module. Mixing of the power and logic cables may cause noise from the power cables
to interrupt the signals in the logic cables. This can lead to intermittent axis faults or
repeatability problems. See Figure 15 and 16 for a layout of the cable connections.
CAUTION!
Make sure the main power is turned off on the back of the electrical cabinet before plugging in
the cables.
