3.3.2 Setting up frequency and PID commands
You can set up the desired frequency and PID commands by using
and
keys on the keypad.
It is also possible to set up the frequency command as load shaft speed, motor speed etc. by setting
function code E48.
Setting up a frequency command
Using
and
keys (Factory default)
(1) Set function code F01 to "0:
/
keys on keypad." This can be done only when the inverter
is in Running mode.
(2) Press the /
key to display the current reference frequency. The lowest digit will blink.
(3) If you need to change the frequency command, press the
/
key again. The new setting
will be automatically saved into the inverter's internal memory and retained even when the
power is off. When the power is turned on next time, the setting will be used as an initial
reference frequency.
• If you have set function code F01 to "0:
/
keys on keypad" but have selected a
frequency command source other than frequency command 1 (i.e., frequency command
2, frequency command via communication, or multi-frequency command), then the
and
keys are disabled to change the current frequency command even in Running
mode. Pressing either of these keys just displays the current reference frequency.
• When you start specifying the reference frequency or any other parameter with the
/
key, the least significant digit on the display blinks; that is, the cursor lies in the least
significant digit. Holding down the
/
key changes data in the least significant digit
and generates a carry, while the cursor remains in the least significant digit.
• After the least significant digit blinks by pressing the
/
key, holding down the
key for more than 1 second moves the cursor from the least significant digit to the most
significant digit. Further holding it down moves the cursor to the next lower digit. This
cursor movement allows you to easily move the cursor to the desired digit and change
the data in higher digits.
• By setting function code C30 to "0:
/
keys on keypad" and selecting frequency
command 2, you can also specify or change the frequency command in the same
manner using the
/
key.
You can set a reference frequency not only with the frequency (Hz) but also with other menu items
(motor speed, load shaft speed, line speed and constant feeding rate time) depending on the setting
of function code E48 (= 3, 4, 5 or 6) as listed in Table 3.3.
