Setting the Frequency using External (0 - 10 V Voltage/4 - 20 mA Current)
Signal and Operating using an External Start Signal
1) Connect the cables to the motor and power source.
2) Connect a start/stop switch between the control
terminal F and CC (for forward rotation) or
between R and CC (for reverse rotation).
External voltage command:
Set the command voltage to 0 V. Apply the
command voltage between the control
terminal VIA
and CC (on the 0 V side).
External current command:
Set the command current to 4 mA.
Apply the command current between the
control terminal II and CC (on the 0 V side).
(See "CONNECTION OF CONTROL SIGNALS.")
3) Turn on the power.
4) Set the parameter CMO8 to "0". (See "Setting
the Starting and Stopping Methods.")
5) Set the parameter FMO8 to "0". (See "Setting
the Frequency Instruction Method.")

(4 to 20 mA) is used, set the
parameter F20I to "20".
7) "0. 0 " is displayed on the display unit.
8) Turn on the forward or reverse
switch.
9) Increase the voltage or current
command gradually.
