- 66 - Aries Controller Hardware Installation Guide
General Troubleshooting Guidelines
The Aries Controller design features easy connectivity, auto-detect functions,
and reliability. In addition, LEDs on the front panel of the unit provide quick
identification of AC power, drive, and Ethernet status. If, after following the
installation guidelines in Chapter 2, 3, and 4, your drive/controller does not
function properly, use the guidelines and procedures in this chapter to
troubleshoot. These guidelines also apply to troubleshooting a malfunction
during normal operation of the drive.
A problem with the drive typically can be traced to one of four areas: power,
power-up sequence, communications, and motor control. If your system is
not functioning properly, follow the steps indicated for each of these areas.
Power
Check the status LEDs (Figure 36).
Figure 36 Ethernet Network and Drive/Controller Status LEDs
If neither the Ethernet Network Status LED nor the Drive/Controller Status
LEDs are illuminated, do the following:
1. Look for problems with AC power. Check the AC power source(s). Also
check Input Power / Mains connections (L1, L2, and
earth ground
terminals for Motor Input Power, and C1, C2, and
earth ground
terminals for Control Input Power).
2. If the AC wiring is correct but no LEDs illuminate, remove all connections
to the unit (Ethernet cables, Drive I/O, Motor Feedback, Motor Input
Power, and Output Power), leaving the Control Input Power C1, C2, and
earth ground terminals connected. Apply power to the drive. If any
LEDs illuminate, there is a short in one of the disconnected cables.
