Settings for N.C. and N.O. input for the following functions were selected
at the same time:
• External Search Command 1 and External Search Command 2 (61 vs. 62)
• Fast Stop N.O. and Fast Stop N.C. (15 vs. 17)
• KEB for Momentary Power Loss and High Slip Braking (65, 66, 7A, 7B
vs. 68)
• Motor Switch Command and Accel/Decel Time 2 (16 vs. 1A)
• KEB Command 1 and KEB Command 2 (65, 66 vs. 7A, 7B)
• FWD Run Command (or REV) and FWD/REV Run Command (2-wire)
(40, 41 vs. 42, 43)
• External DB Command and Drive Enable (60 vs. 6A)
• Motor Switch Command and Up 2/Down 2 Command (16 vs. 75, 76)
Check for contradictory settings assigned to the multi-function input
terminals at the same time. Correct setting errors.
One of the following settings was entered while H1-oo = 2 (External
Reference 1/2):
• b1-15 = 4 (Pulse Train Input) but the pulse train input selection is not set
for the frequency reference (H6-01 > 0)
• b1-15 or b1-16 set to 3 but no option card is connected
• Although b1-15 = 1 (Analog Input) and H3-02 or H3-10 are set to 0
(Frequency Bias)
Correct the settings for the multi-function input terminal parameters.
H2-oo = 38 (Drive Enabled) but H1-oo is not set to 6A (Drive Enable).
H1-oo = 7E (Direction Detection) although H6-01 is not set to 3 (for
V/f Control with PG using terminal RP as speed feedback input).
Digital Operator Display Error Name
oPE04 Initialization required
Cause Possible Solutions
The drive, control board, or terminal board has been replaced and the
parameter settings between the control board and the terminal board no
longer match.
To load the parameter settings to the drive that are stored in the terminal
board, set A1-03 to 5550. Initialize parameters after drive replacement by
setting A1-03 to 1110 or 2220.
Digital Operator Display Error Name
oPE05 Run Command/Frequency Reference Source Selection Error
Cause Possible Solutions
Frequency reference is assigned to an option card (b1-01 = 3) but an input
option card is not connected to the drive.
Reconnect the input option card to the drive.
The Run command is assigned to an option card (b1-02 = 3) but an input
option card is not connected to the drive.
Frequency reference is assigned to the pulse train input (b1-01 = 4), but
terminal RP is not set for frequency reference input (H6-01 > 0)
Set H6-01 to “0”.
Although the digital card input is set for BCD special for a 5 digit input (F3-01
= 6), the data length is set for 8 bit or 12 bit (F3-03 = 0, 1).
Set the input data for 16 bit (F3-03 = 2).
The following values have been set while an AI-A3 option card is installed:
• The source of frequency reference setting is assigned to an option card
(b1-01 = 3).
• The action for the analog card is set for separate terminal input (F2-01 =
0).
Make sure parameters are set properly.
Digital Operator Display Error Name
oPE06
Control Method Selection Error
Correct the setting for the control method.
Cause Possible Solutions
A control mode has been selected that requires a PG option card to be
installed, but no PG encoder is installed (A1-02 = 1, 3, or 7).
• Connect a PG option card.
• Correct the value set to A1-02.
Digital Operator Display Error Name
oPE07
Multi-Function Analog Input Selection Error
A contradictory setting is assigned to multi-function analog inputs H3-02,
H3-06, or H3-10 and PID functions conflict.
