b-038 reverse command
0
：
Motor can be reversed
1
：
Motor can not rotates reversely and all commands can make the motor
rotates forward;
b-039 SF
,
SR input filter factor
It is designed for the suppression of system interference.When using the SF, SR
terminals control frequent forward and reverse of inverter, if the value is bigger, the
filter is stronger, but the inverter will response slowly. It is suggested to set under the
guidance of the manufacturer.
b-040 DC braking duration before start
Determine DC braking duration time before start according to different load
conditions, which is the value of parameter b-040. It is being noted that:
（
1
）
If use for pump loads, don’t need DC braking before start, at this time set
this parameter as 0.0, namely no DC braking before start.

are
independent, the two will no affect each other.
Extended function (group E)
E-000 frequency setting
Display top-class setting frequency according to priority, unit: Hz.
Because this operation can be done during stop period, it can be used to check
setting input signal.
E-001 given value
PID regulation function is enabled, that is to say, when [P-000] = 1, [P-013]
= 10, the value of [E-001] is the percentage of setting value in maximum value, as
shown at below:
[E-001] =
