‹ Operation Errors
An operation error will occur if there is an invalid setting or a contradiction between two parameter settings. It
won't be possible to start the Drive until the parameters have been set correctly. (The alarm output and fault
contact outputs will not operate either.)
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
OPE01
kVA Selec-
tion
Incorrect Drive capacity
setting The Drive capacity setting doesn't match the Unit. (Contact your Yaskawa represen-
tative.)
OPE02
Limit
Parameter setting range
error The parameter setting is outside of the valid setting range. When this error is dis-
played, press the ENTER Key to display U1-34 (
OPE fault parameter) .
OPE03
Terminal
Multi-function input
selection error
One of the following errors has been made in the multi-function input (H1-01 to H1-
10) settings:
• The same setting has been selected for two or more multi-function inputs.
• An up or down command was selected independently. (They must be used
together.)
• The up/down commands (10 and 11) and Accel/Decel Ramp Hold (A) were
selected at the same time.
• Speed Search 1 (61, maximum output frequency) and Speed Search 2 (62. set fre-
quency) were selected at the same time.
• The up/down commands (10 and 11) were selected while PID Control Mode
Selection (b5-01) was enabled.
• Positive and negative speed commands have not been set at the same time.
• The emergency stop command NO and NC have been set at the same time.
OPE05
Sequence
Select
Option Card selection
error The Option Card was selected as the frequency reference source by setting b1-01 to
3, but an Option Card isn't connected (C option).
OPE06
PG Opt Miss-
ing
Control method selec-
tion error V/f control with PG feedback was selected by setting A1-02 to 1, but a PG Speed
Control Card isn't connected.
OPE07
Analog
Selection
Multi-function analog
input selection error
The same setting has been selected for the analog input selection and the PID func-
tion selection.
• H3-09 = B and H6-01 = 1
• H3-09 = C and H6-01 = 2
b1-01 (Reference Selection) is set to 4 (pulse input) and H6-01 (Pulse Train Input
Function Selection) is set to a value other than 0 (frequency reference).
OPE08
Parameter selection
error
A setting has been made that is not required in the current control method. Ex.: A
function used only with open-loop vector control was selected for V/f control. When
this error is displayed, press the ENTER Key to display U1-34 (
OPE fault parameter) .
OPE09
PID control selection
error
The following settings have been made at the same time.
• b5-01 (PID Control Mode Selection) has been set to a value other than 0.
• b5-15 (PID 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.
