9.4 4-DIGIT
DISPLAY:
The 4-digit display provides readout of drive status, operating parameters, and
faults. See Table 7, for the Digital Readout Codes displayed and their descriptions.
WARNING! Wait at least 1 minute before opening the cover. Be sure the main power switch
or circuit breaker is in the "OFF" position before servicing the drive. Do not depend on the green
Power On LED (ON), located on the drive's PC board, as shown in Figure 4, on page 9, or the
Status LEDs and the 4-Digit Display, located on the front cover, to no longer be illuminated as a
guaranteed power off condition.

Mode and a non-valid parameter change
has been attempted.
Keypad Communication Error
Indicates that the keypad failed to initialize
when the drive is powered up. This is an
abnormal condition – contact our Sales
Department.
