(9) The output frequency does not
increase due to the torque
limiter operation.
Check whether the data of torque control levels (F40, F41, E16, E17)
are set to appropriate values. Also, check whether torque limit 2/1
switching signal [TL2/TL1] is correct.

Correct the data of F40, F41, E16 and E17 or reset them to the
factory defaults.

Set the TL2/TL1 correctly.
(10) Bias and gain incorrectly
specified.
Check the data of the function codes (F18, C50, C32, C34, C37, C39,
C42, C44, C55-C72).

Readjust the bias and gain to appropriate values.
(11) External wirings of terminals
[X1]-[X5] are not connected
correctly. Or settings are not
correct.
Check that the reference frequency has been entered correctly, using
Menu “I/O Checking” on the keypad.

Connect the external circuit wirings of terminals [X1]-[X5] correctly.

Set up the data of E01-E05 correctly.

Set up the data of C05-C19 correctly (Setting of multistep
frequency).
(12) Speed set value is not
changing. (Keypad operation)
Check whether it changes by changing the speed command value of
keypad.

Press / keys to change the speed command value.
[ 3 ] The motor runs in the opposite direction to the command
Possible Causes Check and Measures
(1) Wiring to the motor is incorrect. Check the wiring to the motor.

Connect terminals U, V, and W of the inverter to the U, V, and W
terminals of the motor, respectively.
(2) Incorrect connection and
settings for run commands and
rotation direction commands
(FWD and REV).
Check the data of function codes (E98 and E99) and the connection.

Correct the data of the function codes and the connection.
(3) A run command (with fixed
rotational direction) from the
keypad is active, but the
rotational direction setting is
incorrect.
Check the data of function code F02 (Operation method).

Change the data of function code F02 to “2: / Keypad operation
(forward rotation)” or “3: / Keypad operation (Reverse rotation)”.
(4) The rotation direction mode of
the motor is opposite to that of
the inverter.
The rotation direction of IEC-compliant motors is opposite to that of non
compliant motors.

Switch the FWD/REV signal setting.
(5) The function code data related
to the speed command are
incorrect.
Check the function code data. See Chapter 8 “BLOCK DIAGRAMS FOR
CONTROL LOGIC.”

Set correct data.
