oPE10
V/f Data Setting Error
One of the following setting errors has occurred:
E1-04 ≥ E1-06
E1-06 ≥ E1-07
E1-07 ≥ E1-09
or E1-09 ≥ E1-11
Cause Possible Solutions
V/f pattern setting error Correct the settings for E1-04, E1-06, E1-07, E1-09, and E1-11.

oPE11
Carrier Frequency Setting Error
Correct the setting for the carrier frequency.
Cause Possible Solutions
The following simultaneous contradictory settings
have occurred: C6-05 > 6 and C6-04 > C6-03
(carrier frequency lower limit is greater than the
upper limit)
If C6-05 ≤ 6, the drive operates at C6-03
Correct the parameter settings.
The upper and lower limits between C6-02 and
C6-05 are contradictory
HOA Keypad Display Error Name
oPE16 Energy Saving Constants Error
Cause Possible Solutions
The following contradictory settings are true:
A1-02 = 0, S1-01 =1, and b8-01 = 1
Correct the parameter settings.

oPE27
BP Program Error
Bypass mode is not correctly configured.
Cause Possible Solutions
If digital inputs A4, A5, or A7 or digital outputs
A4 or A5 are programmed, then all must be
programmed
Correct the parameter settings.
Digital inputs A4, A5, or A7 and digital outputs A4
or A5 are programmed and one of the following
conditions is true:
• H1-0o = 0 (3-Wire Sequence)
• L5-01 > 0 and S4-01 = 1 (Auto Transfer of Fault)
• H1-oo≤ A6 and H2-oo = A6
• H1-oo = A6 and H2-oo≤ A6

oPE28
Sequence Timer Error
One or more of the sequence timers is not set in the correct order.
Cause Possible Solutions
One of the following contradictory settings is true:
• S2-01 > S2-02
• S2-06 > S2-07
• S2-11 > S2-12
• S2-16 > S2-17
Correct the parameter settings.

oPE30
Incorrect Input Voltage Adjustment
The input voltage offset adjustment has not been performed.
Cause Possible Solutions
• o2-04, Drive Model Selection, setting changed.
• ERPROM failed for the input voltage offset.
