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.

YASKAWA TOEPC71061782C GA800 Drive Installation & Primary Operation
Causes
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]
The Energy Saving parameters are not set in the
applicable setting range.
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.
The value set in F1-01 [Encoder 1 Pulse Count
(PPR)] does not agree with the number of encoder
pulses.
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]
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]
Causes
The torque reference was more than 20% during
Auto-Tuning or the no-load current that was
measured after Auto-Tuning is more than 80%.
The motor nameplate data entered during Auto-
Tuning is incorrect.
The rated current value is incorrect.
20 Troubleshooting
Possible Solutions
Correct the parameter settings.
Make sure that E5-xx is set correctly as specified by the motor
nameplate data.
Set E2-02, E2-03, and E2-06 correctly.
• Examine the F1-01 value and the number of encoder pulses.
• Set F1-01 correctly.
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).
• Set parameters H2-21 ≤ H2-22.
• Set parameters H2-27 ≤ H2-28.
Possible Solutions
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
• If you can uncouple the motor and load, remove the motor from
the machine and do Rotational Auto-Tuning again.
• If you cannot uncouple the motor and load, use the results from
Auto-Tuning.
• Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
Do Auto-Tuning again and set the correct rated current shown on the
motor nameplate.
