Diagnostic & Troubleshooting 6 - 14
Troubleshooting
Due to parameter setting errors, faulty wiring, etc., the Drive and motor may not operate as expected when the system is started
up. If this occurs, use this section as a reference and apply the appropriate measures.
If a fault is displayed on the digital operator, refer to Fault Detection, Table 6.1.
! If Parameter Cannot Be Set
Use the following information if a Drive parameter cannot be set.
"The display does not change when the INCREASE and DECREASE keys are pressed.
The following causes are possible.
The Drive is operating (drive mode).
There are some parameters that cannot be set during operation. Remove the run command and then set the parameters.
Parameter write enable is input.
This occurs when "parameter write enable" (set value: 1B) is set for a multi-function digital input terminal (H1-01 to H1-05). If
the parameter write enable input is OFF, the parameters cannot be changed. Turn it ON and then set the parameters.
Passwords do not match. (Only when a password is set.)
If the parameter A1-04 (Password) and A1-05 (Password Setting) numbers are different, the parameters for the initialize mode
cannot be changed. Enter the correct password in A1-04.
If you cannot remember the password, display A1-05 (Password Setting) by pressing the Shift/Reset Key and the MENU Key
simultaneously while in the A1-04 display. Reset the password and input the reset password in parameter A1-04.
"OPE01 through OPE11 is displayed.
The set value for the parameter is wrong. Refer to Operator Programming Errors in this chapter and correct the setting.
"CPF00 or CPF01 is displayed.
This is a Digital Operator communications error. The connection between the Digital Operator and the Drive may be faulty.
Remove the Digital Operator and then re-install it.
