Chapter 4 Explanation of Functions<br />
4.2 Function Mode<br />
4.2.1 Output frequency setting<br />
The output frequency setting function allows you to set the inverter<br />
output frequency.<br />
You can set the inverter output frequency with this function (F001)<br />
only when you have specified "02" for the frequency source setting<br />
(A001). For other methods of frequency setting, see Section 4.2.4,<br />
"frequency source setting (A001)."<br />

F001: Output frequency setting<br />
A001: Frequency source setting<br />
A020/A220/A320:<br />
Multispeed frequency setting,<br />
1st/2nd/3rd motors<br />
C001 to C008:<br />
Terminal [1] to [8] functions<br />
(If the setting of function "A001" is other than "02", function "F001" operates as the frequency command<br />
monitoring function.)<br />
The frequency set with function "F001" is automatically set as the Multispeed frequency setting (A020). To<br />
set the second and third multispeed s, use the multispeed frequency setting, 2nd motor, function (A220)<br />
and multispeed frequency setting, 3rd motor, function (A320), or use function "F001" for the setting after<br />
turning on the SET and SET3 signals. For the setting using the SET and SET3 signals, assign the SET<br />
function (08) and SET3 function (17) to intelligent input terminals.<br />
If the set output frequency is used as the target data for the PID function, PID feedback data will be<br />
displayed in percent (%). ("100%" indicates the maximum frequency.)<br />

4.2.2 Keypad Run key routing<br />
Related code<br />
When you enter operation commands via the digital operator, the Keypad F004: Keypad Run key routing<br />
Run key routing function allows you to select the direction of motor<br />
operation.<br />
This function is ineffective when you use the control terminal block or remote operator to input operation<br />
commands.<br />
Item Function code Data Description<br />
00 Forward operation<br />
Keypad Run key routing F004<br />
01 Reverse operation<br />
4.2.3 Rotational direction restriction<br />
Related code<br />
The rotational direction restriction function allows you to restrict the<br />
b035: Rotational direction restriction<br />
direction of motor operation.<br />
This function is effective regardless of the specification of operation command input device (e.g., control<br />
circuit block or digital operator).<br />
If an operation command to drive the motor in a restricted direction is input, the inverter (digital operator)<br />
will display .<br />
Item Function code Data Description<br />
00 Both forward and reverse operations are enabled.<br />
