6.6 Programming Errors

Programming Error Codes, Causes, and Possible Solutions

A 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 6.10 for the appropriate action. When

an oPE appears on the HOA keypad display, press the ENTER button to view U1-18 and see which parameter is causing the

oPE.

oPE02

Parameter Range Setting Error

Use U1-18 to find parameters set outside the range.

Cause Possible Solutions

Parameters were set outside the possible setting

range

• Set parameters to the proper values by checking the modified constants menu and verifying that

settings are within the limits.

• Set Z1-01 to 1 to re-initialize the drive and bypass.

Set parameters to the proper values by checking the modified constants menu and verifying that

settings are within the limits.

Note: When multiple errors occur simultaneously, other errors are given precedence over oPE02

Multi-Function Input Selection Error

A contradictory setting is assigned to multi-function contact inputs Z2-01 to Z2-08.

Cause Possible Solutions

• The same function is assigned to two

multi-function inputs

• Excludes “Not used” and “External Fault”

• Ensure all multi-function inputs are assigned to different functions.

• Re-enter the multi-function settings to ensure this does not occur.

Settings for N.C. and N.O. input for the following

functions were selected simultaneously:

• External Search Command 1 and External

Search Command 2 (61 vs. 62)

• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)

• KEB for Momentary Power Loss and High Slip

Braking

(65, 66, 7A, 7B vs. 68)

• KEB Command 1 and KEB Command 2 (65, 66

vs. 7A, 7B)

• FWD Run Command (or REV) and FWD/REV

Run Command (2-wire) (40, 41 vs. 42, 43)

• Drive Enable (60 vs. 6A)

• Check if contradictory settings have simultaneously been assigned to the multi-function input

terminals.

• Correct setting errors.
