shall not work in low frequency for a long time. Otherwise, motor service lifespan will be shortened due
to overheating.
2. Correlation of Fmax, Fup and Fdown: 0.00Hz ≤Fdown ≤Fup≤Fmax ≤600.00Hz
F01.11
Operation when command
frequency lower than lower
limit frequency
Range:0
～
1
Default: 0
F01.12
Lower limit frequency
running time
Range:0.0
～
6000.0s
Default:0.0s
0: Run at lower limit frequency
In case command frequency is lower than lower limit frequency, the running should be at lower
limit frequency.
1: Run at 0 Hz would be activated after the time delay
If frequency command is lower than lower limit frequency, run at 0 Hz would be activated after the
time delay set by F01.12. When lower limit frequency is 0, this limitation is invalid.
F01.13
Up to this frequency, start
frequency compensation
Range: 0.00
～
600.00Hz
Default: 50.00Hz
F01.14
Frequency compensation per
50Hz
Range: 0.00
～
50.00Hz
Default: 0.00Hz
When frequency exceeded the value set by function code F01.13,output frequency will scale up
the values that set by F01.14 for each exceeding 50Hz
Group F02 Start/Stop Control Start/Stop Control
F02.00
Run command
Range:0
～
2
Default: 0
This parameter sets run command source. Run commands include “start, stop, forward
，
reverse
，
jog”, etc.
0: Keypad control (LED off)
Control run command through RUN, STOP/RESET and MF.K keys on keypad (set multifunction
key MF.K to JOG by F16.00). Refer to Chapter 4 about the operation of keypad.
1: Terminal control (LED on)
Controls run command via DI terminals. Perform FORWARD and REVERSE by DI terminals. The
control modes are two-wire mode and three-wire mode selectable. See Group F04 for details of
designation and wiring regulation of DI terminals.
2: Communication control (LED blinking)
Master device is able to control run command through built-in RS485 serial communication
interface of drive. Refer to parameters Group F15 and appendix for further information about
programming.
Run command from keypad, terminals and communication can be switched by terminals “run
command switched to keypad control”, “run command switched to terminal control” and “run command
switched to communication control”.
Multifunction key MF.K can be set to “run command sources shifted” key through parameter
F16.00. When MF key is pressed under this setting; run command will be shifted during keypad control,
terminal control and communication control circularly.
F02.01
Running direction
Range:0
～
1
Default: 0
0: Forward
1: Reverse
You can change the rotation direction of the motor just by modifying this parameter without
changing the motor wiring. Modifying this parameter is equivalent to exchanging any two of the motor’s
U, V, W wires.
Note:
The motor will resume running in the original direction after parameter initialization. Do not use
this function in applications where changing the rotating direction of the motor is prohibited after
system commissioning is complete.
F02.02
Reverse-proof action
Range:0
～
1
Default: 0
0: Reverse enabled
1: Reverse disabled
In some applications, reverse is likely to result in equipment damage. This parameter is used to
prevent reverse running.
