Variable Speed AC Motor Drives
SM-PLUS
Quick Reference Guide
This guide is intended as an aid to configure the SM-Plus drive.
NOTE: Before installing and operating the SM-Plus drive, please
read and become familiar with the SM-Plus Series installation and
operation manual.
Shown below is a sample wiring diagram for a typical three-wire
start/stop control, using momentary contacts for start and stop
commands, and a selector switch for direction.
Set Parameter 17 (Rotation) to Forward and Reverse (02).
Set Parameter 10 (TB-13A) to Start Reverse (06).

DISPLAY DESCRIPTION
Speed Reference Codes
CP CONTROL PAD: The drive speed is controlled by the and buttons on the front of the drive.
EI
EXTERNAL CURRENT: The drive speed is controlled by a 4-20 mA signal between TB-25
and TB-2.
EU
EXTERNAL VOLTAGE: The drive speed is controlled by a 0-10 VDC signal between 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: Contacts wired to TB-13B and 13C are used to increase and decrease the drive speed.
Pr1-Pr7 PRESET SPEEDS #1-7: The drive speed is set by the selected Preset Speed (Parameters 31-37).
Status Indication
br DC BRAKING: The DC braking circuit is activated.
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.
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).
LC FAULT LOCKOUT: Failed three restart attempts. 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.
SP START PENDING: This is displayed during the 15 second interval between restart attempts.
Diagnostic Codes
AF HIGH TEMPERATURE FAULT: Ambient termperature is too high.
CF
CONTROL FAULT: A blank EPM, or EPM with corrupted data has been installed. Perform a
factory reset (Parameter 48).
cF INCOMPATIBILITY FAULT: An EPM with a different parameter version has been installed.
dF DYNAMIC BRAKING FAULT: The drive has sensed the dynamic braking resistors are overheating.
EF
EXTERNAL FAULT: TB-13A and/or TB13C is set as an external fault input and TB-13A and/or
TB-13C is open with respect to TB-2.
GF DATA FAULT: User data and OEM defaults in the EPM are currupted.
HF
HIGH DC BUS VOLTAGE FAULT: Line voltage is too high; Deceleration rate is too fast;
Overhauling load. Fast deceleration and overhauling loads may require dynamic braking.
JF SERIAL FAULT: The watchdog timer has timed out, indicating that the serial link has been lost.
LF LOW DC BUS VOLTAGE FAULT: Line voltage is too low.
OF
OUTPUT TRANSISTOR FAULT: Phase to phase or phase to ground short circuit on the
output: Failed output transistor: Boost settings are too high: Acceleration rate is too fast.
PF
CURRENT OVERLOAD FAULT: VFD is undersized for the application: Mechanical problem with
the driven equipment.
SF SINGLE-PHASE FAULT: Single-phase input power has been applied to a three-phase drive.
UF
START FAULT: Start command was present when the drive was powered up. Must wait
2 seconds after power-up to apply Start command if START METHOD is set to NORMAL.
F1 EPM FAULT: The EPM is missing or damaged.
F2-F9, Fo INTERNAL FAULTS: The control board has sensed a problem. Consult factory.
