YASKAWA GA800 600 V Drive - Auto-Tuning Errors and Troubleshooting

18 Troubleshooting
80 YASKAWA TOEPC7106170VA GA800 600 V Drive Installation & Primary Operation
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.
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.
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.
◆ Auto-Tuning Errors
This table gives information about errors detected during Auto-Tuning. If the drive detects an Auto-Tuning error, the
keypad will show the error and the motor will coast to stop. The drive will not send notification signals for faults and
alarms when Auto-Tuning errors occur.
Two types of Auto-Tuning errors are: Endx and Erx. Endx identifies that Auto-Tuning has successfully completed
with calculation errors. Find and repair the cause of the error and do Auto-Tuning again, or set the motor parameters
manually. You can use the drive in the application if you cannot find the cause of the Endx error.
Erx identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning again.
