Precautions for setting write

· Perform parameter setting change during an inverter stop basically in the PU operation mode or
combined operation mode. The parameter setting can not be changed in the External operation mode or
during inverter operation. (Read is performed independently of the operation mode.) Note that some
parameters can be written even in the External operation mode or during operation. Therefore, refer to
the inverter manual.
· As Pr. 77 Parameter write selection = "0" in the initial setting, parameter can be written only during an
inverter stop. (Read is allowed even during operation.) Note that some parameters can be written
always. Refer to the inverter manual for details of Pr. 77.
· In addition to the above case, setting write cannot be performed when:
1) The parameter number selected does not exist in the parameter list; or
2) The value entered is outside the setting range.
· When write cannot be performed and the "Setting Err." appears, press

and make setting once more.
