• Parameters F0.01~F0.09 are frequency commands used for multi-step
speed operation as shown in Fig 5.3.
• In multi-step speed operation, JOG command has the top priority.
Thus, when JOG command is on, the frequency command is changed
to F0.09 regardless of terminal status of multi-step speed reference 1~3.
• In keypad mode (B0.01=1) and communication mode (B0.01=3), the
value in F0.01 becomes the active frequency command.

F1.01
F1.02
• Parameter F1.01 and F2.02 are used to set the upper and lower limit of
output frequency respectively.
• The setting unit of F1.01 and F1.02 is the percentage of the maximum
utput frequency (C0.02).
