Table 13.15 – Drive Will Not Reverse Motor Direction
Indication Cause(s) Corrective Action
None Digital input is not
selected for reversing
control. Check Digital In”x” Sel.
Choose correct input and
program for reverse.
Digital input is
incorrectly wired. Check input wiring.
Direction Mode (190)
parameter is
incorrectly
programmed. Reprogram Direction
Mode (190) for analog
bipolar or digital unipolar
control.
Motor wiring is
improperly phased for
reverse. Switch two motor leads.
A bipolar analog
speed command input
is incorrectly wired or
signal is absent. 1. Use meter to check that
an analog input voltage
is present.
2. Check wiring.
Positive voltage
commands forward
direction.
Negative voltage
commands reverse
direction.
Table 13.16 – Stopping the Drive Results in a Decel Inhibit Fault
Indication Cause(s) Corrective Action
Decel Inhibit fault
screen.
LCD status line
indicates Faulted.
The bus regulation
feature is enabled and
is halting deceleration
due to excessive bus
voltage. Excess bus
voltage is normally due
to excessive
regenerated energy or
unstable AC line input
voltages.
Internal timer has halted
drive operation.
1. Reprogram bus
regulation (parameters
161 and 162) to
eliminate any Adjust
Freq selection.
2. Disable bus regulation
(parameters 161 and
162) and add a
dynamic brake.
3. Correct AC input line
instability or add an
isolation transformer.
4. Reset drive.
