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
reversal
If the terminal is valid, PID action direction becomes opposite 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; and 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 Ais replaced by the
preset frequency (F0.01)
40

source auxiliary setting
and preset frequency
When the terminal is active, the frequency source B is replaced with
the preset frequency (F0.01)
43
PID parameter
switching
When DI terminal is used to switch PID parameters (E2.19 = 1), if the
terminal is invalid, PID parameters use E2.13~E2.15; if the terminal is
valid, PID parameters use E2.16~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.

the configured frequency detection threshold, and the output is reset to OFF when the operating frequency
drops below the configured level minus the hysteresis value.
The above parameters are used to set the threshold level of output frequency, and the hysteresis value below
which the output is canceled. F7.24 is the hysteresis percentage of the frequency threshold level (F7.23). The
below figure is the schematic diagram of FDT operation.

8. Fault alarm and countermeasures
ST150 can provide effective protection against a number of fault situations. In case of abnormal operation,
if a protection function is invoked, the inverter will stop output, the fault relay contact (in factory configuration)
of the inverter will engage, and the fault code will be displayed on the display panel of the inverter. Before
consulting the service department, user can perform a self-check, analyze the fault cause and find out the
solution according to the instructions of this chapter. If the fault is caused by any of the reasons described in the
right column as requiring technical support, please consult your sales contact or directly contact our company’s
support department by phone or at i[email protected].
