Operator Programming Errors
■
oPE Codes, Causes, and Possible Solutions
An Operator Programming Error (oPE) occurs when a contradictory parameter is set or an individual parameter is set to an inappropriate value.
The drive will not operate until the parameter or parameters causing the problem are set correctly. An oPE, however, does
not trigger an alarm or fault output. If an oPE occurs, investigate the cause and refer to Table 37 for the appropriate
action. When an oPE appears on the operator display, press the ENTER button to view U1-18 and see which parameter is causing the oPE.
Table 37 oPE Codes, Causes, and Possible Solutions
Digital Operator Display oPE01 oPE02 oPE03 oPE04
Error Name
Drive Capacity Setting Fault
Drive capacity and the value set to o2-04 do not match.
Parameter Range Setting Error
Use U1-18 to find parameters set outside the range.
Multi-function Digital Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-03 to H1-08.
Terminal Board Mismatch Error oPE05 oPE06 oPE07 oPE08 oPE10 oPE16 oPE18 oPE20 oPE21
Reference Source Selection Error
Control Mode Selection Error
Correct the setting for the control method.
Multi-function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02 and H3-10.
Parameter Selection Error
A function has been set that cannot be used in the motor control method selected.
V/f Pattern Setting Error
The following setting errors have occurred where:
E1-04 is greater than or equal to E1-06, E1-06 is greater than or equal to E1-07, E1-07 is greater than or equal to E1-09, or E1-09 is greater than or equal to E1-11.
Energy Savings Constants Error
Parameter Setting Error, Online Tuning Parameter Setting Error
• The input from load cell with load condition 1 (S3-29) is set to the same value as load condition 2
(S3-30).
• DWELL 2 related parameters are not set correctly.
• Parameters that control Online Tuning are not set correctly.
PG-F3 Setting Error
The encoder signal frequency is too high.
Elevator Parameter Setting Fault
Elevator parameters are not set correctly.
