1: advanced V/F control
This control mode introduced flux closed loop control
idea, and achieved a large improvement of torque
response of motor control in full frequency range,
torque output ability in low frequency, without the
sensitivity to motor parameter as field-oriented vector
control. It is especially suitable to situation where
there is certain requirements for starting torque (like
drawbench, ball mill, etc.).
2: open loop current vector control (sensitive to
motor parameter)
As a real current vector control mode, it has both high
torque output performance as flux control mode and
flexible torque output. But considering its sensitivity
to motor parameter, the operator had better activate
the dynamic self-learning of motor parameters for a
better effect.
3: reserved
4: separation type V/F control
With this control mode, the output voltage and
frequency of VFD can both be controlled individually,
not according a constant V/F relation. It can be used in
areas like variable-frequency power source and EPS.
Note: factory default is 0 for above 55KW, and 1 for
under 55KW.
F0.06
Operation command channel
0~2
0
This function code is used for choosing the physical
channel for receiving operation commands like run
and stop.
0: keypad run command channel
Controlled with keys in keypad like
RUN
,
STOP/RESET
,
M-FUNC
.
1: terminal run command channel
Controlled by muli-function terminals defined as FWD,
REV, JOG forward, JOG reverse.
2: communication run command channel
Controlled with communication method via upper
computer.
Note:
Even during running status, the run command channel
can be changed by modifying this function code set
value. Please set carefully!

0: digital set 1 ( , encoder)
The frequency is originally set as F0.12, but can be
adjust with key
or encoder. The modified
frequency value will be saved to F0.12 after power
down (if no need for saving, set the F0.10 as 1).
1: digital set 2 (up/down terminal adjust)
The initial value of frequency is F0.13. The running
