HOA Keypad Display
oPE10
Cause
V/f pattern setting error
HOA Keypad Display
oPE11
Cause
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
The upper and lower limits between C6-02 and
C6-05 are contradictory
HOA Keypad Display
oPE16
Cause
The following contradictory settings are true:
A1-02 = 0, S1-01 =1, and b8-01 = 1
HOA Keypad Display
oPE27
Cause
If digital inputs A4, A5, or A7 or digital outputs
A4 or A5 are programmed, then all must be
programmed
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)
HOA Keypad Display
oPE28
Cause
One of the following contradictory settings is true:
• S2-01 > S2-02
• S2-06 > S2-07
• S2-11 > S2-12
• S2-16 > S2-17
HOA Keypad Display
oPE30
Cause
• o2-04, Drive Model Selection, setting changed.
• ERPROM failed for the input voltage offset.

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
Correct the settings for E1-04, E1-06, E1-07, E1-09, and E1-11.
Carrier Frequency Setting Error
Correct the setting for the carrier frequency.
Correct the parameter settings.
Energy Saving Constants Error
Correct the parameter settings.
BP Program Error
Bypass mode is not correctly configured.
Correct the parameter settings.
Sequence Timer Error
One or more of the sequence timers is not set in the correct order.
Correct the parameter settings.
Incorrect Input Voltage Adjustment
The input voltage offset adjustment has not been performed.
Contact Yaskawa or your nearest sales representative for information on clearing the error.
