Fault Name
oFC02
Option Fault (CN5-C)
Two identical options are connected at the same time.
Cause
Possible Solution
AI-A3 option connected to CN5-C connector
while another option was connected to CN5-A
port.
Only one of these options, AI-A3, DI-A3, or SI-
can be
connected to the drive at the same time.

Fault Name
oPE05
Run command/frequency reference source selection error.
Cause
Possible Solution
Frequency reference is assigned to an option
(b1-01 = 3) but an option is not connected.
Reconnect the option to the drive.
These parameters are set at the same time:
• b1-01 = 3 (Frequency Reference Selection 1 =
Option PCB)
• F2-01 = 0 or 2 (Analog Input Function
Selection = 3 Independent Channels or 3
Additional Channels)
Correct the parameter settings.
The following values have been set while an
option is installed:
• H1-
= 2 (External Reference 1/2 Selection)
• b1-15 = 3 (Option PCB)
• The action for the analog card is set for
separate terminal input (F2-01 = 0).
Make sure parameters are set properly.

Fault Name
oPE07
Multi-Function Analog Input Selection Error
Cause
Possible Solution
At least two analog input terminals are set to the
same function (i.e., at least two of these
parameters has the same setting: H3-02, H3-10, or
H3-06).
Change the settings to H3-02, H3-10, or H3-06 so that functions
no longer conflict.
Note:
It is possible to set these functions to multiple analog input
terminals at the same time:
• Setting value 0 (Frequency Reference)
• Setting values F and 1F (Not Used)
The following simultaneous contradictory
settings:
• H3-02, H3-10, or H3-06 = B (PID Feedback)
while H6-01 = 1 (PID Feedback)
• H3-02, H3-10, or H3-06 = C (PID Target
Value) while H6-01 = 2 (pulse train input sets
the PID target value)
• H3-02, H3-10, or H3-06 = C (PID Target
Value) while b5-18 = 1 (enables b5-19 as the
target PID value)
Disable one of the PID selections.
