Operation Errors
An operation error will occur if there is an invalid setting or a contradiction between two constant settings. The inverter will not
start until the constants have been set correctly. (The alarm output and fault contact outputs will not operate wither.)
Error
The inverter capacity setting doesn
,
t match the unit. (Contact your YASKAWA representative.)
The constant setting is out of the valid setting range.
Display Meaning
The same setting has been selected for two or more multi-function inputs (H1-01 to 05) or UP or
DOWN command was selected independently, etc.
An option card is not connected when the option card was selected as the frequency reference
source by setting b1-01 to 3.
A PG speed control card is not connected when V/f control with PG was selected by setting
A1-02 to 1.
The same setting has been selected for the analog input selection and the PID function selection.
A setting not required in the control mode has been selected.
PID sleep function is valid (b5-01 0 and b5-15 0) and stop method has been set to 2 or 3.
Constants E1-04, E1-06, E1-07, and E1-09 do not satisfy the conditions.
Constant setting error occurred.
A verification error occurred when writing EEPROM.
