TECO F510 series - Auto-Tuning Error

52
LED display Possible solutions
ADC Voltage
Error
 Check the input voltage
signal and the voltage on
the control board.
EEPROM
Archiving Error
 Reconnect and if the
warning signal appears
again, replace the circuit
board.
 Contact TECO for more
information.
Control Board
Error
 Replace the control
board.
Wrong Running
Direction Error
 Cancel the run command
for another direction on
the terminal of control
board.
PTC Signal
Loss
 Check if MT terminal and
GND terminal are
connected.
Parameters
Locked
 Correct password input at
parameter 13-07
Password
Setting Error
 Password input at the
second time is the same
as that at the first time
when the password lock
function enables.
Operator
Reading Error
 Check if the inverter is
normally connected to the
operator.
RDE*
Operator
Writing Error
 Check the inverter’s
firmware version/ control
mode/ models
WRE*
Operator
Verifying Error
 Check if the inverter is
normally connected to
the operator.
VRYE*
Repeat Run
Command
 Cancel the run command
in reverse direction from
the external terminal.
Operator Read
Prohibit
 Set parameter 16-08 to 1
(Allow to read inverter
parameters and save it
to the operator).
RDP*
External
Emergency
Stop
 Remove & shutdown the
run command of external
emergency stop and
reset it to multi-function
digital input.
LED display Possible solutions
Zero Speed
Stop Warning
 Set up the frequency
command.
Overload of Air
Compressor
 Check if the compressor
load used is higher than
the standard one.
PID feedback
signal loss
 Check 23-19 setting.
 Make sure correct
installation and PID
feedback signal.
* RDE、WRE、VRYE、RDP warning signals are
only displayed in LCD keypad.
4.4 Auto-tuning Error
When a fault occurs during auto-tuning of a
standard AC motor, the display will show the
“AtErr” fault and the motor stops. The fault
information is displayed in parameter 17-11.
Note: The fault contact output does not
energize with an auto-tuning fault.
Refer to Table 4.3 for fault information
during tuning, cause and corrective
action.

01
Motor data input
error.
 Check the motor
tuning data (17-00 to
17-09).
 Check inverter
capacity
02
Motor lead to
lead resistance
R1 tuning error.
 Check the motor
tuning data (17-00 to
17-09).
 Check motor
connection.
 Disconnect motor
load.
 Check inverter current
detection circuit and
DCCTs.
 Check motor
installation.
