1.6 Power Wiring (continued)
1.6.5 Auxiliary Power, Single Supply
Figure T1.4 below shows how to wire main and auxiliary power to the SMD17K units when using a single
power supply. Colors in parentheses are the appropriate wire colors for the CNPL-2M and CNPL-5M cables.

1.6.6 Auxiliary Power, Dual Supply
Figure T1.5 below shows how to wire main and auxiliary power to the SMD17K units when using two power
supplies. Note that the two supplies can supply different voltages. Colors in parentheses are the appropriate
wire colors for the CNPL-2M and CNPL-5M cables.

1.6.7 Power Supply Troubleshooting
When troubleshooting systems that use the DCPower
AUX
supply, the SMD17K will respond to motion com-
mands by updating the motor position and status bits even if the DCPower
MAIN
supply input is disconnected.
The only indication that the DCPower
MAIN
supply is disconnected is that the motor has no holding torque and
motion does not physically occur.
If Stall Detection is enabled, the Stall_Detected bit will trip if the move is greater than 45°. The
Stall_Detected bit is bit 14 of Status Word 1.
Verify that the DCPower
MAIN
supply is connected to the SMD17K before proceeding.
