• The same function is assigned to two multi-function inputs.
• Excludes "Not used" and "External Fault."
The Up command was set but the Down command was not, or vice versa
(settings 10 vs. 11).
The Up 2 command was set but the Down 2 command was not, or vice versa
(settings 75 vs. 76).
• Run/Stop command for a 2-wire sequence was set (H1-oo = 42), but
Forward/Reverse command (H1-oo = 43) was not.
• "Drive Enable" is set to multi-function input S1 or S2 (H1-01 = 6A or
H1-02 = 6A).
Two of the following functions are set simultaneously:
• Up/Down Command (10 vs. 11)
• Up 2/Down 2 Command (75 vs. 76)
• Hold Accel/Decel Stop (A)
• Analog Frequency Reference Sample/Hold (1E)
• Offset Frequency 1, 2, 3 Calculations (44, 45, 46)
The Up/Down command (10, 11) and PID control (b5-01) are enabled
simultaneously.
Settings for N.C. and N.O. input for the following functions were selected
simultaneously:
• 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)
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)
H2-oo is set to 38 (Drive Enabled) and H1-oo is not set to 6A (Drive
Enable).
Digital Operator Display
The drive, control board, or terminal board have been replaced and the
parameter settings between the control board and the terminal board no
longer match.
Digital Operator Display
Frequency reference is assigned to an option card (b1-01 = 3) and an input
option card is not connected to the drive.
The Run command is assigned to an option card (b1-02 = 3) and an input
option card is not connected to the drive.

Multi-Function Input Selection Error
A contradictory setting is assigned to multi-function contact inputs H1-01
to H1-08.
Possible Solutions
• Ensure all multi-function inputs are assigned to different functions.
• Re-enter the multi-function settings to ensure this does not occur.
Properly set the functions that required for use in combination with other
functions.
Properly set the functions that required for use in combination with other
functions.
• Check if contradictory settings have simultaneously been assigned to the
multi-function input terminals.
• Correct setting errors.
Set b5-01 to 0 to disable control PID or disable the Up/Down command.
• Check if contradictory settings have simultaneously been assigned to the
multi-function input terminals.
• Correct setting errors.
Correct the settings for the multi-function input terminal parameters.
Initialization Required, Term <–> Ctrl Chg
Possible Solutions
Set A1-03 to 5550 to load the parameter settings stored in the terminal board
to the drive. Initialize parameters after drive replacement by setting A1-03
to 1110 or 2220.
Run Command/Frequency Reference Source Selection Error
Possible Solutions
Reconnect the input option card to the drive.
