These commands are set in Digital Inputs (H1-xx,
F3-10 to F3-25, 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.
These settings were entered 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.
These settings were entered while H1-xx = 2
[External Reference 1/2 Selection]:
• b1-15 = 3 [Option PCB] or b1-16 = 3 [Run
Command Selection 2 = Option PCB]
• No option card is connected to the drive.
Connect an input option card to the drive.
These settings were entered 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, H3-05, H3-09 = 1 [Terminal A1, A2, A3
Signal Level Select = -10 to +10V (Bipolar
Reference)]
Remove one of the function settings.
These parameters are set at the same time:
• H1-xx = 62 [Speed Search from Fref]
• H5-22 = 1 [Speed Search from MODBUS =
Enabled]
Remove one of the function settings.
These settings do not agree:
• A PG-RT3 option is connected to the drive.
• H1-xx = 16 [Motor 2 Selection] is set.
Correct the parameter settings.
Note:
The Motor Switch function is not available with the PG-RT3
option.

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.
The following 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.
