vibration.
LED “0000”: PWM wave mode
0: PWM mode 1
It output high quality sine wave while low speed to gain good low frequenc trait, low noise. It reduce
parts on/off times to reduce loss while high speed. But the noise is big.
1: PWM mode 2
It gains high quality current wave. Noise is small, but loss is big and termperature rise up high.
2: PWM mode 3
It can reduce parts on/off times, reduce temperature rice up, but the noise is big.
F0.19 Parameter
initialization
Setting range: 0-2
Factory set: 0
0: Not act
1: Recover factory setting
2: Clear malfunction records Clear all
[FA.25-FA.44]
mistake history.
Note: 1: Keyboard shows SRVE while recover factory setting. SRVE disappear while initialization finished.
2: Not change [F0.16] and [F4.11-F4.14] setting while recover factory setting.
3: If power off while recover factory setting. It can not finish. It need recover after power on again.
F0.20
AVR function selection
Setting range: 0-2
Factory set: 2
0: Invalid
1: All valid
2: invalid while ACC, valid while other state
AVR is output voltage auto adjust function. When it is invalid, output voltage changes according to input voltage. When
it is valid, output voltage keeps as setting if min input voltage is bigger than the output voltage setting (rated voltage).
But output voltage reduces as input voltage reduced if min input voltage is lower than the rated output voltage.

Start-up mode:
0: Start by start-up frequency [F1.02]
start-up frequency and
[F1.03]
start-up frequency hold time control the
frequency inverter start. It is suitable for big static friction torque and small load inertia occasion or occasion with
exterior machine brake equipment. Motor spindle can keep static before restart after stop.
1: DC brake and start. Firstly [F1.04]
brake current and
[F1.05]
brake time give certain energy to motor with load
(electromagnetic hold brake). Then start by start-up frequency. It is suitable for stop state, small inertia load with REV
and FWD.
2: Speed track, direction judge and start
Detect speed and direction firstly, then start as the speed detected out and
run to given frequency according to ACC/DEC time.
