L
and
M
buttons on the front of the drive.
EI
EXTERNAL CURRENT: Speed is controlled by a 4-20 mA signal wired to TB-25 and TB-2.
EU
EXTERNAL VOLTAGE: Speed is controlled by a 0-10 VCD signal wired to TB-5 and TB-2.
JG
JOG: The drive is in Jog mode, and the speed is set by Preset Speed #2 (Parameter 32).
OP
MOP (Motor Operated Pot): Contacts wired to TB-13B and TB-13C are used to increase and

STATUS AND WARNING MESSAGES
DISPLAY
DESCRIPTION
br
DC BRAKING: The DC braking circuit is activated.
cE
“cE” will be displayed if an EPM with a different parameter version is installed and then an
attempt is made to change parameter settings without performing the TRANSLATE function.
Refer to PROGRAM SELECTION (Parameter 48).
CL
CURRENT LIMIT: The output current has exceeded the CURRENT LIMIT setting (Parameter
25) 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 13.2.
LC
FAULT LOCKOUT: The drive has failed three restart attempts and now 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 (both upper decimal points blinking): The drive has stopped decelerating
to avoid tripping into an HF fault due to regenerative energy from the motor.
