Troubleshooting

Cause Possible Solutions
Attempted to use a function in the V/f motor control
method that is only possible in Open Loop Vector Control.
Check the motor control method and the functions
available.
Simple V/f with PG was enabled while not in V/f Control
(H6-01 = 3).
To use Simple V/f with PG, ensure the motor control
method has been set to V/f Control (A1-02 = “0”).
In Open Loop Vector Control, n2-02 is greater than n2-03
Correct parameter settings so that n2-02 is less than
n2-03.
In Open Loop Vector Control, C4-02 is greater than C4-06
Correct parameter settings so that C4-02 is less than
C4-06.
In PM Open Loop Vector Control, parameters E5-02 to
E5-07 are set to 0.
• Set the correct motor code in accordance with the motor
being used (E5-01).
• When using a special-purpose motor, set E5- in
accordance with the Test Report provided.
The following conditions are true in PM Open Loop
Vector Control:
E5-03 does not equal 0
E5-09 are both E5-24 equal to 0, or neither equals 0
Set either E5-09 or E5-24 to the correct value, then set
the other to “0”.
Set the motor-rated current for PM to “0” (E5-03).
Note: Other errors are given precedence over OPE08 when multiple errors occur at the same time.
LED Operator Display Error Name
oPE09
PID Control Selection Fault
PID control function selection is incorrect.
Requires that PID control is enabled (b5-01 = 1 to 4).
Cause Possible Solutions
The following contradictory settings have been made at
the same time:
b5-15 does not equal 0.0 (PID Sleep Function Operation
Level)
The stopping method is set to either DC injection braking
or coast to stop with a timer (b1-03 = 2 or 3).
• Set b5-15 to another value besides 0.
• Set the stopping method to coast to stop or ramp to stop
(b1-03 = “0” or “1”).
LED Operator Display Error Name
oPE10
V/f Data Setting Error
The following setting errors have occurred where:
E1-04 is greater than or equal to E1-06 is greater than or
equal to E1-07 is greater than or equal to E1-09.
Or the following setting errors have occurred:
E3-04 is greater than or equal to E3-06 is greater than or
equal to E3-07 is greater than or equal to E3-09.
Cause Possible Solutions
–
Correct the settings for E1-04, -06, -07 and -09 (or E-04,
-06, -07, -09 for motor 2).
LED Operator Display Error Name
oPE11
Carrier Frequency Setting Error
Correct the setting for the carrier frequency.
