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.
Code Name Causes Possible Solutions
End1 Excessive Rated Voltage Setting
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%. • 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.
End2 Iron Core Saturation Coefficient
The motor nameplate data entered during Auto-
Tuning is incorrect. • Make sure that the input motor nameplate data is correct.
• Do Auto-Tuning again and correctly set the motor nameplate
data.
Auto-Tuning results were not in the applicable
parameter setting range, and
E2-07 or E2-08 [Motor
Saturation Coefficient 2] have temporary values.
• Examine and repair damaged motor wiring.
• If you can uncouple the motor and load, remove the motor from
the machine and do Rotational Auto-Tuning again.
End3 Rated Current Setting Alarm The rated current value is incorrect. Do Auto-Tuning again and set the correct rated current shown on the
motor nameplate.
End4 Adjusted Slip Calculation Error
The Auto-Tuning results were not in the applicable
parameter setting range.
The motor rated slip that was measured after
Stationary Auto-Tuning was 0.2 Hz or lower.
The motor rated slip that was measured after
compensation with
E2-08 [Motor Saturation
Coefficient 2] is not in the applicable range.
The secondary resistor measurement results were not
in the applicable range.
• Make sure the input motor nameplate data is correct.
• Do Rotational Auto-Tuning again and correctly set the motor
nameplate data.
• If you cannot uncouple the motor and load, do Stationary Auto-
Tuning 2.
End5 Resistance Tuning Error
The Auto-Tuning results of the Line-to-Line
Resistance were not in the applicable range. • Make sure that the input motor nameplate data is correct.
• Examine and repair damaged motor wiring.
End6 Leakage Inductance Alarm
The Auto-Tuning results were not in the applicable
parameter setting range. Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
A1-02 [Control Method Selection] setting is not
applicable.
• Examine the value set in A1-02 .
• Make sure that the input motor nameplate data is correct, and do
Auto-Tuning again.
