124 YASKAWA TOEPC71061737B GA800 Drive Installation & Primary Operation
Code Name Causes Possible Solutions
These parameters are set at the same time:
• b5-01 = 3, 4 [Fref + PID Trim, D = Fdbk), Fref +
PID Trim (D on feedback)]
• d2-02 ≠ 0.0
Correct the parameter settings.
oPE10 V/f Data Setting Error
The parameters that set the V/f pattern do not satisfy
these conditions:
• For motor 1: 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]
• For motor 2: E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤
E3-04 [Minimum Output Frequency ≤ Mid Point A
Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
Set the parameters correctly to satisfy the conditions.
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.
oPE13 Pulse Monitor Selection Error
H6-06 = 101, 102, 105, or 116 [Terminal MP
Monitor Selection = Frequency Reference, Output
Frequency, Motor Speed, Output Frequency after Soft
Starter] has not been set when H6-07 = 0 [Terminal
MP Frequency Scaling = 0 Hz].
Set H6-06 correctly.
oPE15 Torque Control Setting Error
More than one parameter is selecting torque control at
the same time.
• d5-01 = 1 [Torque Control Selection = Torque
Control]
• H1-xx = 71 [MFDI Function Select = Torque
Control]
Correct the parameter settings.
oPE16 Energy Saving Constants Error
The Energy Saving parameters are not set in the
applicable setting range.
Make sure that E5-xx is set correctly as specified by the motor
nameplate data.
oPE18 Online Tuning Param Setting Err
The parameters that control online tuning are set
incorrectly. In OLV control, one of these parameters
was set when n6-01 = 2 [Online Tuning Selection =
Voltage Correction Tuning]:
• E2-02 [Motor Rated Slip] is set to 30% of the
default setting or lower.
• E2-06 [Motor Leakage Inductance] is set to 50%
of the default setting or lower.
• E2-03 = 0 [Motor No-Load Current = 0 A] has
been set.
Set E2-02, E2-03, and E2-06 correctly.
oPE20 PG-F3 Setting Error
The value set in F1-01 [Encoder 1 Pulse Count
(PPR)] does not agree with the number of encoder
pulses.
• Examine the F1-01 value and the number of encoder pulses.
• Set F1-01 correctly.
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).
These parameter pairs are set incorrectly:
• H2-21 [Comparator 1 Lower Limit] > H2-22
[Comparator 1 Upper Limit]
• H2-27 [Comparator 2 Lower Limit] > H2-28
[Comparator 2 Upper Limit]
• Set parameters H2-21 ≤ H2-22.
• Set parameters H2-27 ≤ H2-28.
