6.6 Operator Programming Errors
At least two analog input terminals are set to the same function (i.e., at least
two of these parameters has the same setting: H3-02, H3-06, or H3-10).
The following simultaneous contradictory settings:
• H3-02, H3-06, or H3-10 = B (PID Feedback) while H6-01 (Pulse Train
Input) = 1 (PID Feedback)
• H3-02, H3-06, or H3-10 = C (PID Target Value) while H6-01 = 2 (pulse
train input sets the PID target value)
• H3-02, H3-06, or H3-10 = C (PID Target Value) while b5-18 = 1 (enables
b5-19 as the target PID value)
• H6-01 = 2 (PID target) while b5-18 = 1 (enables b5-19 as the target PID
value)

Attempted to use a function in the V/f Control that is only possible in OLV. Check the motor control method and the functions available.
In Open Loop Vector Control, n2-02 is greater than n2-03
In Open Loop Vector Control, C4-02 is greater than C4-06
In OLV/PM, parameters E5-02 to E5-07 are set to 0.
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 b1-14 (Phase Order Selection) to 1 (Switch phase order) when in using
a PG option card.
In AOLV/PM High Frequency Injection is disabled (n8-57 = 0) and the
minimum frequency (E1-09) is set lower than 1/20 of the base frequency
setting.
Note: Use U1-18 to find parameters that are set outside the specified setting range. Other errors are given precedence over oPE08 when multiple
errors occur simultaneously.
Digital Operator Display
The following simultaneous contradictory settings have occurred:
• b5-15 not 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).
PID control is set to b5-01 = 1 or 2, 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.
PID control is set to b5-01 = 3 or 4, but the lower limit for the frequency
reference (d2-01) is not 0.

oPE10
Cause
Change the settings to H3-02, H3-06, 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, H3-06, and H3-10 at the same time.
Disable one of the PID selections.
Parameter Selection Error
A function has been set that cannot be used in the motor control method
selected.
Correct parameter settings so that n2-02 is less than n2-03.
Correct parameter settings so that C4-02 is less than C4-06.
• Set the correct motor code in accordance with the motor being used
(E5-01).
• When using a special-purpose motor, set E5-oo in accordance with the
test report provided.
• 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).
Correct the parameter settings.
Correct the parameter settings.
PID Control Selection Fault
PID control function selection is incorrect. Requires that PID control is
enabled (b5-01 = 1 to 4).
• Set b5-15 to another value besides 0.
• Set the stopping method to coast to stop or ramp to stop (b1-03 = 0 or 1).
Correct the parameter settings.
V/f Data 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.
• E3-04 is greater than or equal to E3-06, E3-06 is greater than or equal to
E3-07, E3-07 is greater than or equal to E3-09, or E3-09 is greater than
or equal to E3-11.
