3-10 Receiving & Installation MN1851
X1 Motor Connections Motor connections are shown in Figures 3-11 and 3-12.
It is important to connect the motor leads U, V and W correctly at the X1 connector
of the control. Incorrect wiring can cause erratic operation including moves at
peak force until the overcurrent limit trips. This will result in a display of “7” and a
“6” on the monitor. If erratic movement of the motor occurs, turn off power
immediately and check the connections of the motor, hall sensors and encoder.

Notes:
1. Metal conduit or shielded cable should be used. Connect
conduits so the use of Load Reactor* or RC Device* does not
interrupt EMI/RFI shielding.
2. Use same gauge wire for Earth ground as is used for L and N.
(VDE (Germany) requires 10mm
2
minimum, 6AWG).
3. Reference EMC wiring in Section 8.
4. Motor and encoder are phase sensitive. Connect only as
instructed.
Note 2
For three phase controls, this is labeled “PE”.

compliance, connect motor ground to the backplane of the
enclosure.

Note: For CE compliant installations, connect unused leads within the motor cable
to “PE” on both ends of the cable.
M-Contactor If required by local codes or for safety reasons, an M-Contactor (motor circuit
contactor) may be installed. However, incorrect installation or failure of the
M-contactor or wiring may damage the control. If an M-Contactor is installed, the
control must be disabled for at least 20msec before the M-Contactor is opened or
the control may be damaged. M-Contactor connections are shown in Figure 3-13.
