Yaskawa Z1000U - Manual (Page 212)

One of the following settings was entered while
H1-oo = 2 (External Reference 1/2):
• b1-15 or b1-16 set to 3 but no option card is
connected
• Although b1-15 = 1 (Analog Input) and H3-02
or H3-10 are set to 0 (Frequency Bias)
Correct the settings for the multi-function input terminal parameters.
H2-oo is set to 38 (Drive Enabled) and H1-oo
is not set to 6A (Drive Enable)
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

oPE07
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02 or H3-10 and PI functions
conflict.
Cause Possible Solutions
At least two analog input terminals are set to the
same function (i.e., at least two of these parameters
have the same setting: H3-02 or H3-10)
Change the settings to H3-02 and H3-10 so that functions no longer conflict.
Note: Both 0 (Frequency Reference Bias) and F (Not Used) can be set to H3-02 and H3-10
simultaneously.
The following simultaneous contradictory
settings:
H3-02 or H3-10 = C (PI Target Value) while
b5-18 = 1 (enables b5-19 as the target PI value)
Disable one of the PI selections.

oPE08
Parameter Selection Error
A function has been set that cannot be used in the motor control method selected.
Cause Possible Solutions
In OLV/PM, parameters E5-02 to E5-07 are set to
0
When using a special-purpose motor, set E5-oo in accordance with the test report provided.
The following settings have occurred in OLV/PM:
• E5-03 does not equal 0
• E5-09 and E5-24 are both equal to 0, or neither
equals 0
• Set E5-09 or E5-24 to the correct value, and set the other to 0.
• Set the motor rated current for PM to 0 (E5-03).
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.

oPE09
PI Control Selection Fault
PI control function selection is incorrect. Requires that PI 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 (PI 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 PI 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 PI control, but the lower
limit for the frequency reference (d2-01) is not 0 Correct the parameter settings.
