Operation Errors
An operation error will occur if there is an invalid setting or a contradiction between two parameter settings. It
will not be possible to start the Inverter until the parameters have been set correctly. (The alarm output and
fault contact outputs will not operate.)
When an operation error has occurred, refer to the following table to identify and correct the cause of the
errors.
Table 7.3 Operation Error Displays and Incorrect Settings
Display
Meaning
Incorrect settings
Incorrect Inverter
capacity setting
The Inverter capacity setting doesn't match the Unit. (Contact your OMRON repre-
sentative.)
Parameter setting range
error
The Parameter setting is outside of the valid setting range.
Multi-function input
selection error
One of the following errors has been made in the multi-function input (H1-01 to H1-
05) settings:
• The same setting has been selected for two or more multi-function inputs.
• Speed Search 1 (61, maximum output frequency) and Speed Search 2 (62. set fre-
quency) were selected at the same time.
• External Baseblock NO (8) and External Baseblock NC (9) were selected at the
same time.
Option Card selection
error
The Option Card was selected as the frequency reference source by setting b1-01 to
3, but an Option Card is not mounted or connected (C option).
Multi-function analog
input selection error
• H3-09 = B
PI control selection
error
The following settings have been made at the same time.
• b5-01 (PI Control Mode Selection) has been set to a value other than 0.
• b5-15 (PI Sleep Function Operation Level) has been set to a value other than 0.
• b1-03 (Stopping Method Selection) has been set to 2 or 3.
V/f data setting error
Parameters E1-04, E1-06, E1-07 and E1-09 do not satisfy the following conditions:
• E1-04 (FMAX)
≥
E1-06 (FA) > E1-07 (FB)
≥
E1-09 (FMIN)
Parameter setting error
One of the following Parameter setting errors exists.
• C6-05 (Carrier Frequency Gain) > 6, the Carrier Frequency Lower Limit (C6-04)
> the Carrier Frequency Gain(C6-05)
• Upper/lower limit error in C6-03 to 05.
EEPROM write error
A verification error occurred when writing EEPROM.
• Try turning the power supply off and on again.
• Try setting the Parameters again.
