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).

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. |
||
|
|
||
|
CURRENT LIMIT: The output current has exceeded the CURRENT LIMIT setting (Parameter 25) |
||
CL |
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. |
