Chapter 4 Explanation of Functions

4.2 Function Mode

4.2.1 Output frequency setting

F001: Output frequency setting
A001: Frequency source setting
A020/A220/A320:

Multispeed frequency setting,
1st/2nd/3rd motors

C001 to C008:

Terminal [1] to [8] functions

Related code

The output frequency setting function allows you to set the inverter
output frequency.
You can set the inverter output frequency with this function (F001)
only when you have specified "02" for the frequency source setting
(A001). For other methods of frequency setting, see Section 4.2.4,
"frequency source setting (A001)."
(If the setting of function "A001" is other than "02", function "F001" operates as the frequency command
monitoring function.)
The frequency set with function "F001" is automatically set as the Multispeed frequency setting (A020). To
set the second and third multispeed s, use the multispeed frequency setting, 2nd motor, function (A220)
and multispeed frequency setting, 3rd motor, function (A320), or use function "F001" for the setting after
turning on the SET and SET3 signals. For the setting using the SET and SET3 signals, assign the SET
function (08) and SET3 function (17) to intelligent input terminals.
If the set output frequency is used as the target data for the PID function, PID feedback data will be
displayed in percent (%). ("100%" indicates the maximum frequency.)

The frequency set with F001 is equal to the
setting of A020.
The second control frequency set with F001
is equal to the setting of A220.
The third control frequency set with F001 is
equal to the setting of A320.

4.2.2 Keypad Run key routing

F004: Keypad Run key routing

Related code

When you enter operation commands via the digital operator, the Keypad
Run key routing function allows you to select the direction of motor
operation.
This function is ineffective when you use the control terminal block or remote operator to input operation
commands.

4.2.3 Rotational direction restriction

b035: Rotational direction restriction

Related code

The rotational direction restriction function allows you to restrict the
direction of motor operation.
This function is effective regardless of the specification of operation command input device (e.g., control
circuit block or digital operator).
If an operation command to drive the motor in a restricted direction is input, the inverter (digital operator)
will display .
