Troubleshooting
Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not
operate as expected when the system is started up. If that should occur, use this section
as a reference and apply the appropriate measures. If the contents of the fault are dis-
played, refer to
8-1 Protective and Diagnostic Functions.
H
If Parameter Constants Cannot Be Set.
D
The display does not change when the Increment and Decrement Keys are
pressed.
•
Passwords do not match.
If the parameter A1-04 (Password 1) and A1-05 (Password 2) numbers are different, the constants for
the initialize mode cannot be changed. Reset the password. If you cannot remember the password,
display A1-05 (select password) by pressing the Reset/Select Key and the Menu Key simultaneously
while in the A1-04 display. Then reset the password. (Input the reset password in parameter A1-04.)
•
Constant write-in prohibition is input.
This occurs when “program lockout” (set value: 1B) is set for a multi-function input. If the program lock-
out input is OFF, the constants cannot be changed. Turn it ON and then set the constants.
•
The Inverter is operating (drive mode).
There are some constants that cannot be set during operation. Turn the Inverter off and then make the
settings.
D
OPE01 through OPE11 is displayed.
This is a parameter setting error. The set value for the parameter constant is wrong. Refer to
8-1-3
Operation Errors and correct the setting.
D
CPF00 or CPF01 is displayed.
This is a Digital Operator transmission fault. The connection between the Digital Operator and the In-
verter may be faulty. Remove the Digital Operator and then re-install it.
H
If the Motor Does Not Operate
D
The motor does not operate when the Run Key on the Digital Operator is pressed.
•
The operation method setting is wrong.
If parameter b1-02 (run source) is set to “1” (control circuit terminal), the motor will not operate when
the Run Key is pressed. Either press the Local/Remote Key* to switch to Digital Operator operation or
set parameter b1-02 to “0” (Digital Operator).
*
The Local/Remote Key is enabled (set value: 1) or disabled (set value: 2) by means of parame-
ter o2-01. It is enabled when the drive mode is entered.
