5.2.3 Status and Warning Messages
STATUS AND WARNING MESSAGES
DISPLAY DESCRIPTION
br DC BRAKING: The DC braking circuit is activated.
cE
"cE" will be displayed if an EPM from a drive with a previous parameter version is
installed into a new drive, and an attempt is made to change any parameter settings.
The parameters cannot be changed until the Translate function is performed
(parameter 48, setting 06).
CL
CURRENT LIMIT: The output current has exceeded the CURRENT LIMIT setting
(Parameter P25) and the drive is reducing the output frequency to reduce the output
current. If the drive remains in CURRENT LIMIT for too long, it can trip into a CURRENT
OVERLOAD fault (PF).
Er ERROR: Invalid data has been entered or an invalid command was attempted.
GE
“GE” will be displayed if an attempt is made to change the OEM default settings when
the drive is operating in the OEM mode (see Parameter 48).
GF
If “GF” is displayed when a RESET OEM is attempted, it indicates that the OEM defaults
in the EPM are corrupted. If “GF” is displayed upon power-up, it indicates that the OEM
defaults and the user settings in the EPM are corrupted. Refer to Section 4.2.1.
LC
FAULT LOCKOUT: The drive has failed three restart attempts and requires a manual
reset.
SE
SERIAL: The optional remote keypad is active as the user interface instead of the
buttons on the front of the drive. See Parameter 14 - CONTROL.
SP START PENDING: “SP” blinks during the interval between restart attempts.
DECEL OVERRIDE: The drive has stopped decelerating to avoid tripping into an HF fault
due to regenerative energy from the motor.
