Code Name Causes Possible Solutions
When H1-xx = 0 [MFDI Function Select = Brake
Release Check], set H2-xx ≠ 21 [MFDO Function
Select ≠ Brake Release Command]
Set the parameters correctly.
This relation is not established or not set.
• When S4-22 = 1 [L-L 2 Freq Upper Limit Select
= Enabled],set S4-08 [Light-load 2 Activation
Freq] ＜ 3 Hz.
Set the parameters correctly.

oPE23 Parameter Setting Error
When Vector control, set L7-01 and L7-02 < S1-07
and S1-08 [Torque Limit < Brake Release Torque].
Make sure that L7-01 and L7-02 ≧ S1-07 and S1-08.
When each function of crane sequence enables, set
larger value than L7-01 and L7-02 to these
parameters.
• S3-03 and S3-04 [Impact Stop Detect Torque]
• S4-04 and S4-05 [Light-load 1 Detect Torque]
• S5-02 and S5-05 [Overload Detection Torque]
• S6-02 and S6-05 [Overtorque Detection Level]
Set the value smaller than L7-01 and L7-02.

oPE24 Light-load Accel 2 Fault (oL6)
The following commands are set in H1-xx [MFDI
Function Select] simultaneously:
• Setting value 30 [Light-load Accel 1 Enabled]
and setting value 36 [Light-load Accel 1
Enabled]
Remove the function settings that are not in use.

oPE25 Parameter Setting Error
The crane sequence parameter (frequency) setting
error for motor 2 and motor 3.
Set the parameters correctly.
When S1-26 ≠ 0 [Motor2 Brake Delay Time ≠ 0.00
s], set in these ways.
• S1-23 or S1-24 > S1-25 [Motor2 Brake Release
Freq > Motor2 Brake Delay Frequency]
• S1-25 > E3-06 [Motor2 Brake Delay Frequency
> Motor 2 Base Frequency]
• S1-25 > S4-06 [Motor2 Brake Delay Frequency
> Light-load 1 Detect Frequency]
Set the parameters correctly so that these conditions are satisfied.
• S1-23 or S1-24 ≦ S1-25
• S1-25 ≦ E3-06
• S1-25 ≦ S4-06
When S1-26 = 0, set in these ways.
• S1-23 or S1-24 > E3-06 [Motor2 Brake Release
Freq > Motor 2 Base Frequency]
• S1-23 or S1-24 > S4-06 [Motor2 Brake Release
Freq > Light-load 1 Detect Frequency]
Set the parameters correctly so that these conditions are satisfied.
• S1-23 and S1-24 ≦ E3-06
• S1-23 and S1-24 ≦ S4-06
When S1-37 ≠ 0 [Motor2 Slip Prevention Time ≠
0.00 s], set in these ways.
• S1-34 or S1-35 < S1-36 [Motor2 Brake Hold
Freq < Motor2 Slip Prevention Frequency]
• S1-34 or S1-35 = E3-09 = S1-36 [Motor2 Brake
Hold Freq = Motor 2 Minimum Output
Frequency = Motor2 Slip Prevention
Frequency]
Set the parameters correctly so that these conditions are satisfied.
• S1-34 or S1-35 ≧ S1-36
• S1-34 or S1-35 ≠ E3-09 ≠ S1-36
When H1-xx = 35 [MFDI Function Select = Impact
Stop Enable], set S3-01 ≦ S1-34 or S1-35 [Impact
Stop Creep Frequency ≦ Motor2 Brake Hold Freq].
Make sure that S3-01 > S1-34 and S1-35.
