6.4 Operator Programming Errors (OPE)
An Operator Programming Error (OPE) occurs when an inapplicable parameter is set or an individual parameter setting is inappropriate.
The iQpump drive does not operate until the parameter is set correctly. (Alarm output and fault contact do not operate.)
If an OPE occurs, change the appropriate parameter by checking the cause shown in Table 6.4 .

Digital Operator
Display
Description Cause
Corrective
Action
OPE01
kVA Selection
Drive kVA setting error.
The control board was replaced and the
kVA parameter is set incorrectly.
Enter the correct kVA setting (o2-04) by
referring to the iQpump drive model
number in
Appendix B.
OPE02
Limit
Parameter data out of range. Parameter set above the allowable range. Verify the program settings.
OPE03
Terminal
Multi-function input selection fault.
Duplicate functions are selected. Speed
search from maximum frequency and set
frequency are set simultaneously. MOP
Increase (H1-0X = 10) and MOP
Decrease (H1-0X = 11) are not set
simultaneously.
Verify program settings.
(H1-01~H1-05)
OPE05
Sequence Select
Run command is selected through serial
communication at 2CN but option board
is not installed.
Serial communication option board is
not installed, option board is installed
incorrectly. The run command selection
parameter.
b1-02 is set to 3 and option board is not
installed.
Verify that the board is installed. Remove
power to the iQpump drive and connect
the option board once more.
OPE10
V/f Ptrn Setting
V/f data setting fault
V/f parameter settings are not set
correctly.
Check parameters (E1-04 ~ E1-11). A
minimum frequency/voltage value may be
set higher than the maximum frequency/
voltage.
OPE11
CarrFrq/On-Delay
Carrier frequency data setting fault.
Carrier frequency proportional gain C6-
05 > 6 and C6-04 > C6-03. Upper/lower
limit error of C6-03 to 5.0kHz.
Parameter setting incorrect.
Check the program settings and correct
the errors.
ERR
EEPROM R/W Err
It does not match at EEPROM write.
• Power supply is turned OFF.
• Parameter is reset repeatedly.
• Cycle power off and on to iQpump.
• Do a factory initialization (A1-03).
