Digital Operator
Parameters were set outside the allowable setting range.
oPE02
A contradictory setting is assigned to multi-function contact
inputs H1-01 through to H1-08.
• The same function is assigned to two inputs. (this excludes
"External fault" and "Not used")
oPE03
• Input functions which require the setting of other input
functions were set alone.
• Input functions that are not allowed to be used
simultaneously have been set.
• The run command source (b1-02) or frequency reference
source (b1-01) is set to 3 but no option card is installed.
oPE05
• The frequency reference source is set to pulse input but
H6-01 is not 0.
Settings to multi-function analog inputs H3-02 and H3-10
and PID functions conflict.
• H3-02 and H3-10 are set to the same value. (this excludes
oPE07
settings 0 and F)
• PID functions have been assigned to both analog inputs and
the pulse input at the same time.
A function has been set that cannot be used in the control
oPE08
mode selected.(might appear after control mode change)
The V/f pattern setting is incorrect.

Auto-Tuning Errors
Digital Operator
Motor data fault
The input motor data are not valid. (e.g. the base frequency
Er-01
and base speed do not fit).
Minor Fault
Er-02
• The wiring is faulty.
The STOP button was pressed and Auto-Tuning was
Er-03
canceled.
Resistance fault
• Wrong input data.
Er-04
• Auto tuning exceeded the given time frame.
• Calculated values out of range.
No-Load Current Error
• Incorrect data was entered.
Er-05
• Auto tuning took too long.
• Calculated values out of range.
Rated Slip Error
• Wrong data input.
Er-08
• Auto tuning exceeded the given time frame.
• Calculated values out of range.
Current detection error
• One or all output phases are lost.
Er-12
• Current is either too low or exceeds the drives rating.
• The current sensors are faulty.
Excessive V/f Setting
• The torque reference exceeded 20% during Auto-Tuning.
End1
• The calculated no-load current is above 80% of the motor
rated current.
Rated current alarm
End3
Adjusted Slip Calculation Error
End4

Corrective Action
Re-enter the data and repeat Auto-Tuning.
• Check the wiring.
Repeat the Auto-Tuning.
• Check the input data.
• Check the wiring.
• Re-enter the data and repeat the Auto-Tuning.
• Check the wiring.
• Make sure, that the drive rating fits to the motor.
• Check the load. (Auto-Tuning should have been performed
without the load connected.)
• Replace the drive.
• Check the V/f pattern setting.
• Perform Auto-Tuning without the load connected.
• Check the input data and repeat Auto-Tuning.
Check the input data and repeat tuning.
• Make sure the data entered for Auto-Tuning is correct.
• Double check the data that was entered for the Auto-Tuning
process.
• Check the motor and motor cable connection for faults.
