Code Name Causes Possible Solutions
When A1-02 = 5 to 7 [Control Methods for PM
Motors], you used these parameter settings:
• E5-09 = 0.0 [PM Back-EMF Vpeak (mV/(rad/s))
= 0.0 mV/(rad/s)]
• E5-24 = 0.0 [PM Back-EMF L-L Vrms (mV/rpm)
= 0.0 mV/min
-1
]
Set E5-09 or E5-24 to the correct value.
When A1-02 = 5 to 7, you set E5-09 ≠ 0 and E5-24
≠ 0.
Set E5-09 = 0 or E5-24 = 0.
When A1-02 = 6 [PM Advanced Open Loop
Vector], you used these parameter settings:
• n8-57 = 0 [HFI Overlap Selection = Disabled]
• You set E1-09 [Minimum Output Frequency] <
the 5% value of E1-06.
Correct the parameter settings.
When A1-02 = 6, you set these parameters:
• n8-35 = 0 [Initial Pole Detection Method =
Pull-in]
• n8-57 = 1 [Enabled]
Correct the parameter settings.
When A1-02 = 8 [EZOLV], you used these
parameter settings:
• E9-01 = 1, 2 [Motor Type Selection =
Permanent Magnet (PM), Synchronous
Reluctance (SynRM)]
• b3-24 = 2 [Speed Search Method Selection =
Current Detection 2]
When E9-01 = 1 or 2, set b3-24 = 1 [Speed Estimation].

oPE09 PID Control Selection Fault
These parameters are set at the same time:
• b5-15 ≠ 0.0 [PID Sleep Function Start Level ≠
0.0 Hz]
• b1-03 = 2, 3 [Stopping Method Selection = DC
Injection Braking to Stop, Coast to Stop with
Timer]
• Set b5-15 ≠ 0.0.
• Set b1-03 = 0, 1 [Ramp to Stop, Coast to Stop].
These parameters are set at the same time:
• b5-01 = 1, 2 [Enabled (Standard), Enabled (D =
Feedforward)]
• d2-02 ≠ 0.0 [Frequency Reference Lower Limit
≠ 0.0%]
Correct the parameter settings.
These parameters are set at the same time:
• b5-01 = 1, 2 [Enabled (Standard), Enabled (D =
Feedforward)]
• b5-11 = 1 [PID Output Reverse Selection =
Negative Output Accepted]
Correct the parameter settings.
These parameters are set at the same time:
• b5-01 = 3, 4 [Trim (Fref+PID Out, D = Fdbk),
Trim (Fref+PID Out, D = FeedFwd)]
• d2-02 ≠ 0.0 has been set.
Correct the parameter settings.
Note:
The drive detects this error if the PID control function selection is incorrect.
(When b5-01 = 1 to 4 [PID Mode Setting = PID Control Enabled])

oPE10 V/f Data Setting Error
The parameters that set the V/f pattern do not
satisfy these conditions:
• For motor 1: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤
E1-04 [Minimum Output Frequency ≤ Mid Point
A Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
• For motor 2: E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤
E3-04 [Minimum Output Frequency ≤ Mid Point
A Frequency < Base Frequency ≤ Mid Point B
Frequency ≤ Maximum Output Frequency]
Set the parameters correctly to satisfy the conditions.

oPE11 Carrier Frequency Setting Error
These parameters are set at the same time:
• C6-05 > 6 [Carrier Freq Proportional Gain >
6]
• C6-04 > C6-03 [Carrier Frequency Lower Limit
> Carrier Frequency Upper Limit]
Note:
When C6-05 < 7, C6-04 becomes disabled. The
drive sets the carrier frequency to the value set
to C6-03.
C6-02 to C6-05 settings are not in the applicable
setting range.
Set C6-02 to C6-05 correctly.
