3-wire sequence (Setting : 0)
• When 0 is set for multi-function inputs H0.02~H0.05, 3-wire sequence
control is used and terminal 1 becomes run command, terminal 2
becomes stop command. And if terminal 5 has setting 0, it becomes
terminal for forward/reverse run command as shown in Figure 5.15.

Fault reset (Setting : 2)
OFF
Normal operation
ON
Resets the faults when input goes from OFF to ON.
• With the fault reset function, the faults can be reset by the contact
input.
• When a fault occurs, find out the cause of the fault and correct it before
restarting the inverter. The inverter may be damaged if a fault is reset
repeatedly without correcting the cause of fault.

• Method to resume the operation after a fault:
1.Turn OFF the run command.
2.Turn the fault reset input from ON to OFF since a fault can
not be reset with the run command ON.
3. Turn the run command ON again.
Multi-step speed 1~3 and JOG frequency command (Setting : 3~6)
• 8 frequency commands and 1 JOG frequency command can be used.
• 8-step speed operation: (Refer to the Figure 5.3)
B0.02=1(Select the active source of RUN command)
B0.01=1(Select the active source of frequency command)
F0.01=(Frequency1, Main frequency)
F0.02=(Frequency2)
F0.03=(Frequency3)
F0.04=(Frequency4)
F0.05=(Frequency5)
F0.06=(Frequency6)
F0.07=(Frequency7)
F0.08=(Frequency8)
Forward and reverse jogging (Setting : 7~8)
The jogging can be run clockwise or counterclockwise.
Setting
Function
7
Reverse jog command: Runs clockwise at the jog frequency.
8
Forward jog command: Runs counterclockwise at the jog frequency.
• Forward and reverse jog commands have priority over other frequency
commands (e.g. F0.01~F0.08).
• Do not turn on both the forward and reverse jog command.
If the setting 7 and 8 are both ON for more than 500ms, then the
inverter will stop with the stopping method set in B0.03.
• It is not necessary to input the forward/reverse run command since
these jog command alone can operate the inverter.
• These functions run/stop immediately when set on ON/OFF.
At this time, the accel/decel is not applied.
