52 Troubleshooting
Diagnostic LEDs
NRGD05 and NRGD10 series drives are equipped with the
following diagnostic LEDs to aid in troubleshooting. Refer to
Figure 21 (NRGD05) and Figure 22 (NRGD10) for diagnostic
LED locations.
POWER
The green POWER LED lights when AC line voltage is applied
to the drive (the drive’s power supply is active).
RUN
The red RUN LED lights when the drive is enabled.
CURRENT LIMIT (CL/FTL)
The red CURRENT LIMIT LED lights when drive output current
exceeds the threshold set by the CURRENT LIMIT trimpot.
PEAK
The red PEAK LED lights when the drive’s output to the regen
dump circuit exceeds the dump circuit’s maximum input voltage.
When this condition exists, the NRGD drive will switch off its
power control components, coasting the motor to a stop.
However, once the threshold is cleared (bus voltage drops below
the PEAK value), the power components will begin to switch on
at a rate controlled by the speed adjust pot or voltage signal input.
This may lead to sudden, undesired motor restarts or intermittent
motor operation. For this reason, if the PEAK LED lights, always
set the speed adjust pot or input signal to zero speed, then restart
the drive.
