HOA Keypad Display Error Name
H2-oo is set to 38 (Drive Enabled) and H1-oo
is not set to 6A (Drive Enable)
Correct the settings for the multi-function input terminal parameters.
HOA Keypad Display Error Name
oPE04 Initialization Required
Cause Possible Solutions
The drive, control board, or terminal board have
been replaced and the parameter settings between
the control board and the terminal board no longer
match.
Set A1-03 to 5550 to load the parameter settings stored in the terminal board to the drive. Initialize
parameters after drive replacement by setting A1-03 to 2220 or 3330.
HOA Keypad Display Error Name
oPE05 Run Command/Frequency Reference Source Selection Error
Cause Possible Solutions
Frequency reference is assigned to an option card
(b1-01 = 3) and an input option card is not
connected to the drive
Reconnect the input option card to the drive.
The Run command is assigned to an option card
(b1-02 = 3) and an input option card is not
connected to the drive
HOA Keypad Display Error Name
oPE07
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02, H3-10, and H3-06 and PID
functions conflict.
Cause Possible Solutions
At least two analog input terminals are set to the
same function
Change the settings to H3-02, H3-10, and H3-06 so that functions no longer conflict.
Note: Both 0 (Frequency Reference Bias) and F (Not Used) can be set to H3-02, H3-10, and
H3-06 simultaneously.
The following simultaneous contradictory
settings:
H3-02, H3-10, or H3-06 = C (PID Target Value)
while
b5-18 = 1 (enables b5-19 as the target PID value)
Disable one of the PID selections.
HOA Keypad Display Error Name
oPE08 Parameter Selection Error
Cause Possible Solutions
A function has been set that cannot be used in the
control mode.
The bypass only supports V/f control mode. Limit selections to those with V/f mode compatibility.
Note: Use U1-18 to find parameters that are set outside the specified setting range. When multiple errors occur simultaneously, other errors are
given precedence over oPE08.
HOA Keypad Display Error Name
oPE09
PID Control Selection Fault
PID control function selection is incorrect. Requires that PID control is enabled (b5-01 = 1 or 3).
Cause Possible Solutions
The following simultaneous contradictory settings
have occurred:
• b5-15 is not set to 0.0 (PID Sleep Function
Operation Level)
• The stopping method is set to either DC
Injection Braking or coast to stop with a timer
(b1-03 = 2 or 3)
• Set b5-15 to a value other than 0.0.
• Set the stopping method to coast to stop or ramp to stop (b1-03 = 0 or 1).
b5-01 is set to 1, enabling PID control, but the
lower limit for the frequency reference (d2-02) is
not set to 0 while reverse output is enabled
(b5-11 = 1)
Correct the parameter settings.
b5-01 is set to 3, enabling PID control, but the
lower limit for the frequency reference (d2-01) is
not 0
Correct the parameter settings.
