Code Name Causes Possible Solutions
You set these commands in Digital Inputs (H1-xx and
H7-01 to H7-04) at the same time:
• Setting values 61 [Speed Search from Fmax] and
62 [Speed Search from Fref]
• Setting values 65, 66, 7A, 7B [KEB Ride-Thru 1 or
2 Activate] and 68 [High Slip Braking (HSB)
Activate]
• Setting values 16 [Motor 2 Selection] and 1A
[Accel/Decel Time Selection 2]
• Setting values 65, 66 [KEB Ride-Thru 1 Activate]
and 7A, 7B [KEB Ride-Thru 2 Activate]
• Setting values 40, 41 [Forward RUN (2-Wire),
Reverse RUN (2-Wire)] and 42, 43 [Run
Command (2-Wire Sequence 2), FWD/REV (2-
Wire Sequence 2)]
• Setting values 60 [DC Injection Braking
Command] and 6A [Drive Enable]
• Setting values 16 [Motor 2 Selection] and 75, 76
[Up 2 Command, Down 2 Command]
Remove the function settings that are not in use.
Settings for N.C. and N.O. input [H1-xx] for these
functions were selected at the same time:
• Setting value 15 [Fast Stop (N.O.)]
• Setting value 17 [Fast Stop (N.C.)]
Remove one of the function settings.
You entered these settings while H1-xx = 2 [External
Reference 1/2 Selection]:
• b1-15 = 4 [Frequency Reference Selection 2 =
Pulse Train Input]
• H6-01 ≠ 0 [Terminal RP Pulse Train Function ≠
Frequency Reference]
Set H6-01 = 0.
You entered these settings while H1-xx = 2 [External
Reference 1/2 Selection]:
• b1-15 = 3 [Option PCB] or b1-16 = 3 [Run
Command Selection 2 = Option PCB]
• You did not connect an option to the drive.
Connect an input option to the drive.
You entered these settings while H1-xx = 2 [External
Reference 1/2 Selection]:
• b1-15 = 1 [Analog Input]
• H3-02 ≠ 0 [Terminal A1 Function Selection ≠
Frequency Reference] or H3-10 ≠ 0 [Terminal A2
Function Selection ≠ Frequency Reference]
Set H3-02 = 0 or H3-10 = 0.
These parameters are set at the same time:
• H1-xx ≠ 6A [Drive Enable]
• H2-xx = 38 [Drive Enabled]
Correct the parameter settings.
These parameters are set at the same time:
• H6-01 ≠ 3 [PG Speed Feedback (V/F Control)]
• H1-xx = 7E [Reverse Rotation Identifier]
Correct the parameter settings.
These parameters are set at the same time:
• H1-xx = 75/76 [Up 2 /Down 2 Command]
• H3-01, H3-09 = 1 [Terminal A1, A2 Signal Level
Select = 0 to +10V(Without Limit)]
Remove one of the function settings.

oPE05 Run Cmd/Freq Ref Source Sel Err
The setting to assign the Run command or frequency
reference to an option card or the pulse train input is
incorrect.
Correct the parameter settings.
b1-01 = 3 [Frequency Reference Selection 1 =
Option PCB] is set, but there is no option card
connected to the drive.
b1-02 = 3 [Run Command Selection 1 = Option
PCB] is set, but there is no option card connected to
the drive.
Connect an option card to the drive.
These parameters are set at the same time:
• b1-01 = 4 [Pulse Train Input]
• H6-01 ≠ 0 [Terminal RP Pulse Train Function ≠
Frequency Reference]
Set H6-01 = 0.
