7-2 Basic Functions (Group F)
This section describes the output frequency setting, acceleration/deceleration time, and other basic
parameters.
• Use these parameters to set the output frequency of the inverter.
• F001 can be used to set the output frequency only when the Frequency Reference Selection (A001)
is set to 02 (Digital Operator). For other frequency setting methods, refer to Frequency Reference
Selection on page 7-17. F001 functions as the frequency reference monitor when A001 is set to other
than 02.
• Setting a frequency in F001 automatically configures the 1st Multi-step Speed Reference 0 (A020) to
the same value.
To configure the 2nd/3rd control, set the 2nd Multi-step Speed Reference 0 (A220)/3rd Multi-step
Speed Reference 0 (A320), or set F001 with the SET/SET3 terminal turned ON.
To use the SET/SET3 terminal, allocate one of the Multi-function Input S1 to S8 Selection to 08
(SET)/17 (SET3).
• If the output frequency is used as the PID target value, it will be displayed as a percentage [%]. In this
case, 100% is the maximum frequency.
