Description Function
COM
Common point for control
commands
F05=1, Edge triggers(F62=0),and runs forward in falling
edge, stops in rising edge
FWD Forward rotation command
F05=3, Level triggers(F62=0/1/2)
F05=1, Edge triggers (F62=0), and runs reverse in falling
edge, stops in rising edge.
REV Reverse rotation command
F05=3, Level triggers(F62=0/1/2)
JOG Jog command
Level triggers, and executes JOG command in a lower level,
stops in a high level
Multi-step speed/acceleration
F63=1/2,Short-circuited to COM to compose 7-step speed
and acceleration, level triggers, effective in a lower level
Rising/Falling control F04=4,for rising control
SS1
Frequency mode switch Switch the frequency setting mode with SS2, SS3
Multi-step speed/acceleration
F63=1/2,Short-circuited to COM to compose 7-step speed
and acceleration, level triggers, effective in a lower level
Rising/Falling control F04=4,for falling control
SS2
Frequency mode switch Switch the frequency setting mode with SS1,SS3
Multi-step speed/acceleration
Short-circuited to COM to compose 7-step speed and
acceleration, level triggers, effective in a lower level
JOG control
F63=3 COM is short-circuited to SS3 to execute JOG
reverse command, to JOG to execute JOG forward
command, and the previous JOG direction is invalid.
Three-line running control F63=1/2,F62=2 Three-line terminal running for details
Program running restart For selecting the program running restart mode
Rising/Falling control F04=4,for falling control
SS3
Frequency mode switch Switch the frequency setting mode with SS1,SS2
FRE Free Run
Level triggers, and executes free stop command in a lower
level
Control signal
RST Restore Level triggers, executes restore command in falling edge.

2-6. Connection Precautions
※ Don’t install power factor capacitance or resistance-capacitance
absorbing device between the output terminals U, V, W of the
frequency inverter.
※ To disassemble or replace the motor, the input power supply must be
turned off for the frequency inverter.
※ The motor or power supply can be switched on/off only after the
inverter stops its output.
※ In order to minimize the effect of electromagnetic interference, a surge
absorbing device should be installed if used electromagnetic contactor
and relay, etc. is near to the frequency inverter.
※ For external control of frequency inverter, a isolation device should be
used for the control lines or screened cable should be used.
※ A screened cable should be used as the signal connection line for
input command and must be routed separately as well, and it had
better be installed far from the main circuit.
※ When the carrier frequency is less than 3kHz, the distance between
the frequency inverter and motor must not be greater than 50 meters
(maximum). When it is above 4kHz, this distance should be reduced.
The cable for this connection had better be laid in metal conduit.
※ If the frequency inverter is equipped with peripheral devices (such as
filter, reactor), first measure its insulation resistance to the earth with
1000V megohm meter, and ensure the resistance value is not below
4MΩ.
※ If the frequency inverter must be started frequently, don’t switch off its
