If this fault appears, there may be a prob-
lem with software configuration.
To reset the processor, cycle power to chiller,
check VFD_CONF settings and save settings
when exiting VFD_CONF (PIC3)/CFGUMVFD
(PIC6) configuration screen.
Check VFD parameters with Drive Explorer.
17 216 446
The DC bus ripple
has exceeded a
preset level.
Line Voltage imbalance
Check phase-to-phase and phase-to-ground dis-
tribution bus voltage. Increase Line Voltage %
Imbalance in VFD_CONF (PIC3)/CFGUMVFD
(PIC6) screen.

21 225 445 Output PhaseLoss
The current in one or more phases has
been lost or remains below a preset level.
Check Motor Current % Imbalance in VFD_CONF
(PIC3)/CFGUMVFD (PIC6) screen.
24 204 442 Decel Inhibit
The drive is not following a commanded
deceleration because it is attempting to
limit bus voltage.
Verify input voltage is within drive specified
limits.
Verify system ground impedance follows proper
grounding techniques.
Disable bus regulation P186 and/or add dynamic
brake resistor and/or extend deceleration time
P537 and P538.

36 286 438 SW Overcurrent
The drive output current has exceeded
the 1 ms current rating.
Check for excess load, improper DC boost set-
ting, DC brake volts set too high.
