Troubleshooting the Drive
13-13
HW
OverCurrent 12 The drive output current
has exceeded the
hardware current limit. Check programming.
Check for excess load,
improper DC boost setting,
DC brake volts set too high
or other causes of excess
current.
Motor dynamics cannot be
accommodated by
autotuning. Manual tuning
of the current loop
required. Diagnostic Item
#51 may need to be
reduced. Consult technical
support.
Incompat
MCB-PB 106 Drive rating information
stored on the power
board is incompatible
with the Main Control
board. Load compatible version
files into drive.
IR Volts
Range 77 The drive autotuning
default is Calculate and
the value calculated for
IR Drop Volts is not in
the range of acceptable
values. Re-enter motor nameplate
data.
Motor
Overload 7 Internal electronic
overload trip.
Enable/disable with
Fault Config 1 (238).
An excessive motor load
exists. Reduce load so
drive output current does
not exceed the current set
by Motor NP FLA (42).
OverSpeed
Limit
25
Functions such as slip
compensation or bus
regulation have
attempted to add an
output frequency
adjustment greater than
that programmed in
Overspeed Limit (83). Remove excessive load or
overhauling conditions or
increase Overspeed Limit
(83).
