9.2.2 Setting Frequency Command by Keypad
 How to set the frequency command from the keypad during a test run or normal operation?
 How to change the frequency command from an optional remote operator?
 How to change the frequency command while watching the monitor display?
 To set the output frequency command from the keypad according to a parameter setting, set the
"Frequency input source selection [A001]
*1
" to "Parameter setting (02)".
 The output frequency is set according to the "Output frequency setting or monitor [F001]" or the
"Multi-speed 0 [A020]
*1
". (If [F001] is changed, [A020] is also changed to the same value. If "2nd-
motor control [SET]" is turned on, "Multi-speed 0, 2nd-motor [A220]" is changed.)
 To connect the optional remote operator with potentiometer (OPE-SR/OPE-SR mini) and use its
potentiometer [POT] to set the output frequency command, set the "Frequency input source
selection [A001]
*1
" to "External operator POT (00)".
Refer to "7.2.8 Remote Operator Functions" for details regarding operation when a remote
operator is connected.
