5.7 Parameter Setting Errors
YASKAWA TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup 145
Code Name Causes Possible Solutions
oPE10 V/f Data Setting Error
The parameters that set the V/f pattern do not satisfy
these conditions:
• E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04
[Minimum Output Frequency ≤ Mid Point A
Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
Set the parameters correctly to satisfy the conditions.
Code Name Causes Possible Solutions
oPE11 Carrier Frequency Setting Error
These parameters are set at the same time:
• C6-05 > 6 [Carrier Freq Proportional Gain > 6]
• C6-04 > C6-03 [Carrier Frequency Lower Limit
> Carrier Frequency Upper Limit]
Note:
When C6-05 < 7, C6-04 becomes disabled. C6-
03 stays active.
C6-02 to C6-05 settings are not in the applicable
setting range.
Set C6-02 to C6-05 correctly.
Code Name Causes Possible Solutions
oPE12 Incompatible Drive Software
This version of bypass software is not compatible
with the connected drive.
Flash the drive with compatible software.
Code Name Causes Possible Solutions
oPE16 Energy Saving Constants Error
These parameters are set at the same time:
• b8-01 = 1 [Energy Saving Control Selection =
Enabled]
• S1-01 = 1 [Dynamic Noise Control = Enabled]
Disable Energy Saving Control or Dynamic Noise Control.
Code Name Causes Possible Solutions
oPE29 Baud Rate Setting Error
The baud rate setting [H5-02] does not align with the
currently selected protocol [H5-08].
One of these contradictory settings is true:
• H5-08 = 1 and H5-02 ≠3 [Communication
Protocol Selection = Metasys/N2 and
Communication Speed Selection ≠ 9600 bps]
• H5-08 = 2 and H5-02 ≠ 2, 3 [Communication
Protocol Selection = Apogee/P1 and
Communication Speed Selection ≠ 4800 bps, 9600
bps]
• H5-08 = 3 and H5-02 ≠ 3, 4, 5, 7 [Communication
Protocol Selection = BACnet and Communication
Speed Selection ≠ 9600 bps, 19.2 kbps, 38.4 kbps,
76.8 kbps]
Correct the parameter settings.
Code Name Causes Possible Solutions
oPE33 Digital Output Selection Error
These two parameters are set at the same time:
• H2-60 ≠ F [Term M1-M2 Secondary Function ≠
Not Used]
• H2-01 = 1xx [Term M1-M2 Function Selection =
Inverse output of xx]
These two parameters are set at the same time:
• H2-63 ≠ F [Term M3-M4 Secondary Function ≠
Not Used]
• H2-02 = 1xx [Term M3-M4 Function Selection =
Inverse output of xx]
These two parameters are set at the same time:
• H2-66 ≠ F [Term M5-M6 Secondary Function ≠
Not Used]
• H2-03 = 1xx [Term M5-M6 Function Selection =
Inverse output of xx]
Clear the H2-01 to H2-03 = 1xx [Inverse output of xx] settings.
Note:
It is not possible to set H2-01 to H2-03 = 1xx [Inverse output of
xx] when using output functions for logic operations (H2-60,
H2-63, H2-66 ≠ F).
