Code Name
310
Cause
PID control and Up/Down command are
enabled simultaneously.
• b5-01 [PID Function Setting]
• H1-xx = 10 [Up Command] and H1-
xx = 11 [Down Command]
The following commands are set in H1-
xx [MFDI Function Select]
simultaneously:
• Setting values 61 [External Speed
Search command 1] and 62 [External
Speed Search command 2]
• Setting values 65, 66, 7A, 7B [KEB
Ride-Thru 1/2] and 68 [High Slip
Braking (HSB)]
• Setting values 16 [Motor 2 Selection]
and 1A [Accel/Decel Time Selection
2]
• Setting values 65, 66 [KEB Ride-Thru
1] and 7A, 7B [KEB Ride-Thru 2]
• Setting values 40, 41 [Forward Run
Command (2-Wire Seq), Reverse Run
Command (2-Wire Seq)] and 42, 43
[Run Command (2-Wire Sequence 2),
FWD/REV Command (2-Wire Seq 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]
Settings for N.C. and N.O. input [H1-
xx] for the following functions were
selected simultaneously:
• Setting value 15 [Fast Stop (N.O.)]
• Setting value 17 [Fast Stop (N.C.)]
The following 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 [PulseTrain InTerm RP
Func Select ≠ Frequency reference]
The following settings were entered
while H1-xx = 2 [External Reference 1/
2 Selection]:
• b1-15 = 3 [Frequency Reference
Selection 2 = Option PCB] or b1-16
= 3 [Run Command Selection 2 =
Option PCB]
• No option card is connected to the
drive.
The following settings were entered
while H1-xx = 2 [External Reference 1/
2 Selection]:
• b1-15 = 1 [Frequency Reference
Selection 2 = Analog Input]
• H3-02 ≠ 0 [Terminal A1 Function
Selection ≠ Frequency Bias] or H3-10
≠ 0 [Terminal A2 Function Selection
≠ Frequency Bias]
The following parameters are set
simultaneously:
• H1-xx ≠ 6A [Drive Enable]
• H2-xx = 38 [Drive Enabled]

Possible Solution
• Set b5-01 = 0 [PID Function Setting =
Disabled].
• Remove the function Up/Down command
assignments.
Remove the function assignments that will not be
used.
Remove one of the function assignments.
Set H6-01 = 0.
Connect an input option card to the drive.
Set H3-02 = 0 or H3-10 = 0.
Correct the parameter settings.
