6.5 Operator Programming Errors
Digital Operator Display
Attempted to use a function that is not valid for the selected control mode.
In Open Loop Vector Control, n2-02 is greater than n2-03
b1-14 (Phase Order Selection) is set to 1 (Switch phase order) when in using a PG option card. Correct the parameter settings.
Note: Use U1-18 to find parameters that are set outside the specified setting range. Other errors are given precedence over oPE08 when multiple errors occur simultaneously.

Energy saving coefficients are out of the allowable range.

S3-29 and S3-30 are set to the same value, meaning that the input from load cell with load
condition 1 (S3-29) is set to the same value as load condition 2 (S3-30).
The Dwell 2 speed reference in S3-20 is greater than 0.00 but is still less than the Dwell 2 End
Speed in S3-21.
Open Loop Vector Control is selected (A1-02 = 2), Online Tuning is enabled (n6-01 = 2), and
one of the following contradictory settings exists:
• E2-02 is set to 30% or less of its factory default.
• E2-06 is set to 50% or less of its factory default.
• E2-03 = 0

With the entered encoder resolution (F1-01), maximum output frequency (E1-04), and motor
pole number (E5-04,) the calculation encoder signal frequency exceeds 50 kHz (with PG-F3
option) or 20 kHz (with PG-E3 option).

The DC Injection / Position Lock Time at Stop (S1-05) is set to a value lower than the Brake
Close Delay Time (S1-07).
• The deceleration distance (S5-11) is set to value lower than the minimum deceleration
distance (U4-43).
• The stop distance (S5-12) is set to a value lower than the minimum stop distance (U4-44).
Both S5-10 and S5-01 are enabled at the same time.

Parameter Selection Error
A function has been set that cannot be used in the motor control method selected.
Possible Solutions
Check the motor control method and the functions available.
Correct parameter settings so that n2-02 is less than n2-03.
V/f Pattern Setting Error
The following setting errors have occurred where:
E1-04 is greater than or equal to E1-06, E1-06 is greater than or equal to E1-07, E1-07 is
greater than or equal to E1-09, or E1-09 is greater than or equal to E1-11.
Possible Solutions
Correct the settings for E1-04, E1-06, E1-07, E1-09, and E1-11 (for motor 2, correct E3-04,
E3-06, E3-07, E3-09, and E3-11).
Energy Savings Constants Error
Possible Solutions
Check and correct the motor data in E5 parameters.
Parameter Setting Error, Online Tuning Parameter Setting Error
• The input from load cell with load condition 1 (S3-29) is set to the same value as load
condition 2 (S3-30).
• DWELL 2 related parameters are not set correctly.
• Parameters that control Online Tuning are not set correctly.
Possible Solutions
Correct the values set to S3-29 and S3-30.
Correct the values set to S3-20 and S3-21.
Correct the values set to E2-02, E2-03, or/and E2-06.
PG-F3 Setting Error
The encoder signal frequency is too high.
Possible Solutions
• Set F1-01 to the correct encoder resolution.
• Reduce the maximum output frequency of the drive in parameter E1-04 so the encoder
signal frequency at maximum speed is lower than 50 kHz.
Elevator Parameter Setting Fault
Elevator parameters are not set correctly.
Possible Solutions
Correct parameter settings so that S1-05 > S1-07.
• Correct parameter settings so that S5-11 > U4-43.
• Correct parameter settings so that S5-12 > U4-44.
Correct the setting in parameters S5-01 and S5-10.
