Ch
ap
ter 5
32
Immediately DC
braking
If the terminal is active, the inverter switches directly to DC
braking status
33
External fault
normally closed
input
When the signal of external fault normally closed input is
inputted into the inverter, the inverter will report fault Err.15 and
shutdown.
34
Frequency change
enable
If the function is set to be valid, when the frequency changes, the
inverter does not respond to frequency changes until the terminal
state is invalid.
35
PID action direction
as reverse
If the terminal is valid, PID action direction opposites to the
direction set by E2.03
36
External parking
terminal 1
Under keyboard control mode, the terminal can be used to stop
the inverter, same as STOP key on the keyboard.
37
Control command
switch terminal 2
Used to switch between terminal control and communication
control. If the command source is selected as terminal control,
the system will be switched to the communication control mode
when the terminal is active; vice versa.
38 PID integral pause
When the terminal is active, the PID integral adjustment function
is paused, but the proportion and differential adjustments of PID
are still valid.
39
Switch between
frequency source
master setting and
preset frequency
When the terminal is active, the frequency source A is replaced
by the preset frequency (F0.01)
40
Switch between
frequency source
auxiliary setting and
preset frequency
When the terminal is active, the frequency source B is replaced
with the preset frequency (F0.01)
41 Reserve
42 Reserve
43
PID parameter
switching
When DI terminal (E2.19 = 1) is used to switch PID parameters,
if the terminal is invalid, PID parameters use E2.13 to E2.15; if
the terminal is valid, PID parameters use E2.16 to E2.18
44 Custom fault 1
When custom fault 1 and custom fault 2 are active, the inverter
respectively alarms fault Err.27 and fault Err.28, and deals with
them according to the mode selected by the fault protection
action F8.19.
45 Custom fault 2
46
Speed control /
torque control
switching
Switch between speed control mode and torque control mode
under vector control mode. If the terminal is invalid, the inverter
will run at the mode defined by FA.00 (speed/torque control
mode); if the terminal is valid, the inverter will be switched to
another mode.
47 Emergency parking
If the terminal is valid, the inverter will park at the fastest speed,
and the current maintains at the set upper limit during the
parking process. This function is used to meet the requirements
that the inverter needs to stop as soon as possible when the
system is in a emergency state.
48
External parking
terminal 2
In any control mode (keyboard control, terminal control,
communication control), the terminal can be used to decelerate
the inverter until stop, at the time the deceleration time is fixed
for deceleration time 4.
49
Deceleration DC
braking
If the terminal is valid, firstly the inverter decelerates to the
initial frequency of stop DC braking, and then switches directly
to DC braking status.
