If the frequency source is multi-function, the value 100% of C1-00~ C1-15 corresponds to the value of b0-13
(Maximum frequency).
Besides as the multi-speed function, the multi-function can be also used as the PID setting source or the voltage
source for V/F separation, satisfying the requirement on switchover of different setting values.

b3-12
DI filter time
Default
0.010s
Setting Range 0.000s~1.000s
It is used to set the software filter time of DI terminal status. If DI terminals are liable to interference and may cause
malfunction, increase the value of this parameter to enhance the anti-interference capability. However, increase of DI
filter time will slow down the response of DI terminals.
b3-13
Terminal command mode
Default
0
Setting
Range
0 Two-line mode 1
1 Two-line mode 2
3 Three-line mode 1
4 Three-line mode 2
This parameter is used to set the mode in which the frequency inverter is controlled by external terminals. The
following uses DI1, DI2 and DI3 among DI1 to DI12 as an example, with allocating functions of DI1, DI2 and DI3 by
setting b3-00 to b3-02.
0: Two-line mode 1
It is the most commonly used two-line mode, in which the forward/reverse rotation of the motor is decided by DI1
and DI2. The parameters are set as below:
