5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
◼ 3-wire operation
Two types of 3-wire operation can be configured regardless of whether “HLD” or “DIR” are used.
[FWD]
[REV]
[HLD]
停止
逆転
[CM]
正転
[FWD]
[DIR]
[HLD]
停止
正転/
逆転
[CM]
運転
Forward rotation: [FWD]
Reverse rotation: [REV]
Stop: [HLD]
Run: [FWD]
Forward rotation/reverse rotation: [DIR]
Stop: [HLD]
Refer to Function code E01 to E09 (data = 6) for details on “HLD”.
As a setting method of run command, high-priority setting methods (remote/local switch (refer to Chapter 3, Section
3.3.7 ), communication, etc.) are available in addition to the above mentioned settings.
Maximum output frequency 1
F03 specifies the maximum frequency that the inverter outputs. When the device to be driven is set to rated or
higher, the device may be damaged. Make sure to make an adjustment to design mode value of the machinery.
• Data setting range: 5.0 to 599.0 (Hz)
V/f control
(incl. dynamic torque vector control, V/f control with speed sensor)
Speed sensor
upper limit: 100
kHz
Vector control with sensor (induction motors, permanent magnet
synchronous motors)
Speed sensor
upper limit: 100
kHz
Speed sensorless vector control (induction motors, permanent magnet
synchronous motors)
The speed sensor pulse frequency is limited to 100 kHz or less, and therefore it is not possible to output frequencies
higher than this.
Inverter high-speed operation settings can be specified easily. If settings are changed, use the product after
sufficiently checking the motor and machine specification.
Failure to observe this could result in injury or damage.
When changing maximum output frequency (F03) in order to make the operation frequency a larger value,
change the frequency limiter (upper limit) (F15) as well.
