• Digital input commands (FWD) and (REV) are valid for specifying the motor rotation
direction, and the commands (FWD2) and (REV2) are invalid.
• If you have assigned the (FWD) or (REV) function to the [FWD] or [REV] terminal,
you cannot change the setting of function code F02 while the terminals [FWD] and/o
r
[REV] are on.
• Make sure that terminals [FWD] and [REV] are off before changing the (FWD) o
r
(REV) function from the function other than the (FWD) and (REV) functions to (FWD)
or (REV) function. Because, if under this condition you assign the (FWD) or (REV)
function to the [FWD] or [REV] terminal while the terminals [FWD] and/or [REV] are
on, the motor would start running.
When "Local" is selected in Remote/Local switching, the operation of the keypad concerning run
commands varies with the setting of F02. For details, refer to "■Switching the operation mode
between remote and local" in Chapter 3, Section 3.3.1.
F03 Maximum Frequency
F03 specifies the maximum frequency at which the motor can run. Specifying the frequency out of
the range rated for the equipment driven by the inverter may cause damage or a dangerous
situation. Set a maximum frequency appropriate for the equipment.
The inverter can easily accept high-speed operation. When changing the speed setting, carefully
check the specifications of motors or equipment beforehand.
Otherwise injuries could occur.
Modifying F03 data to apply a higher output frequency requires also changing F15 data
specifying a frequency limiter (high).
