ERR
EEPROM R/W Err
After the constants have been set, an operation error will occur if there is an invalid setting or a contradiction
between two constant settings.
It won't be possible to start the Inverter until the constants have been set correctly. (The minor fault output
and fault contact output will not operate, either.)
When an operation error has occurred, refer to the following table to identify and correct the cause of the er-
rors.

Meaning
Incorrect Inverter capacity The Inverter capacity setting doesn't match the Unit. (Contact your Yaskawa repre-
setting
sentative.)
Constant setting range error
The constant setting is outside of the valid setting range.
One of the following errors has been made in the multi-function input (H1-01 to
H1-06) settings:
Multi-function input selection
error
The Option Card was selected as the frequency reference source by setting b1-01 to
Option Card selection error
3, but an Option Card isn't connected.
Control method selection er- Flux vector control was selected by setting A1-02 to 3, but a PG Speed Control Card
ror isn't connected.
Multi-function analog input
selection error
A setting has been made that is not required in the current control method.
Constant selection error
Ex.:
Constants E1-04, E1-06, E1-07, and E1-09 do not satisfy the following conditions:
V/f data setting error
One of the following constant setting errors exists.
Constant setting error
Winding change sequence One of the following errors exists.
error
A verification error occurred when writing EEPROM.
EEPROM write error
Operation Error Displays and Incorrect Settings
Incorrect settings
S The same setting has been selected for two or more multi-function inputs.
S An up or down command was selected independently. (They must be used together.)
S The up/down commands (10 and 11) and Accel/Decel Ramp Hold (A) were selected
at the same time.
S Speed Search 1 (61, maximum output frequency) and Speed Search 2 (62. set fre-
quency) were selected at the same time.
S External Baseblock NO (8) and External Baseblock NC (9) were selected at the same
time.
S The Terminal 13/14 Switch (1F) was selected, but the terminal 14 function selector
(H3-09) wasn't set to frequency reference (1F).
S The same setting (other than 1F) has been selected for H3-05 and H3-09.
S An A1-14B Analog Reference Card is being used and F2-01 is set to 0, but a multi-
function input (H1-01 to H1-06) has been set to Option/Inverter Selection (2).
A function used only with flux vector control was selected for open-loop
vector control.
S E1-04 (FMAX) E1-06 (FA)
S The carrier frequency upper limit (C6-01) > 5 KHz and
the carrier frequency lower limit (C6-02)
S The carrier frequency gain (C6-03) > 6 and (C6-01) > (C6-02).
S Upper/lower limit error in C6-01 to 03 or C8-15.
S Multi-function digital input is set to 80 (winding change) and 16 (Motor 2 selection)
at the same time.
S Multi-function digital input is set to 81 and 82 at the same time.
S Multi-function digital input is set to 81, or b1- - 02 is not set to 5 when P1-01 is not 0.
S Try turning the power supply off and on again.
S Try setting the constants again.
